It is with great pride that Microsoft shares its position as a Leader within the Gartner Magic Quadrant for Field Service Management for the third consecutive year.

As companies across industries navigate a period of uncertainty, every investment in people and technology must be strategic and decisive to help people do more with less—less time, less cost, and less complexity.

Hyper-personalized, self-driven, seamless interaction across any channel at any time is no longer a nice-to-have but a must-have as customers want to engage on their own terms and expect businesses to deliver even better experiences. Earlier this week, we announced the Microsoft Supply Chain Platform. At the core of the Supply Chain Platform is the Microsoft Supply Chain Center, which introduces a ready-made command center for users to manage disparate supply chain data.

It has become clear that ESG environmental and social governance initiatives are becoming a top business priority for many organizations. The opportunity facing business leaders is to find ways to utilize technology to drive a positive impact on business performance and the well-being of society and the environment. If you specify one it will be ignored. The value parameter is used to set the limiting value to which the criteria is applied.

You can also use the synonyms minimum or source to make the validation a little clearer and closer to Excel's description of the parameter:. The maximum parameter is used to set the upper limiting value when the criteria is either 'between' or 'not between' :.

When the option is on the data validation is not applied to blank data in the cell. It is on by default. The dropdown parameter is used to toggle on and off the 'In-cell dropdown' option in the Excel data validation dialog. When the option is on a dropdown list will be shown for list validations.

It has no default value and is only displayed if the input message is displayed. The maximum title length is 32 characters. UTF8 strings are handled automatically in perl 5. The maximum message length is characters. The default error title is 'Microsoft Excel'.

The default error message is "The value you entered is not valid. There are 3 options:. Example 2. Limiting input to an integer greater than a fixed value where the value is referenced from a cell. Example 5. Limiting input to a value in a dropdown list where the list is specified as a cell range. If you specify the height of a row that contains a worksheet object then Spreadsheet::WriteExcel will adjust the height of the object to maintain its default or user specified dimensions.

In this way the object won't appear stretched or compressed in Excel. However, Excel can also adjust the height of a row automatically if it contains cells that have the text wrap property set or contain large fonts.

In these cases the height of the row is unknown to Spreadsheet::WriteExcel at execution time and the scaling calculations it performs are incorrect.

The effect of this is that the object is stretched with the row when it is displayed in Excel. The first thing to note is that there are still some outstanding issues with the implementation of formulas and functions:. However, these constraints will be removed in future versions. They are here because of a trade-off between features and time. The following is a brief introduction to formulas and functions in Excel and Spreadsheet::WriteExcel.

The formula can contain numbers, strings, boolean values, cell references, cell ranges and functions. Named ranges are not supported. Formulas should be written as they appear in Excel, that is cells and functions must be in uppercase. Cells in Excel are referenced using the A1 notation system where the column is designated by a letter and the row by a number. Columns range from A to IV i. This allows you to specify whether a row or column is relative or absolute.

This only has an effect if the cell is copied. The following examples show relative and absolute values. The sheet reference and the cell reference are separated by!

the exclamation mark symbol. If worksheet names contain spaces, commas or parentheses then Excel requires that the name is enclosed in single quotes as shown in the last two examples above. In order to avoid using a lot of escape characters you can use the quote operator q{} to protect the quotes. See perlop in the main Perl documentation. You cannot reference external workbooks.

The following table lists the operators that are available in Excel's formulas. The majority of the operators are the same as Perl's, differences are indicated:.

The range and comma operators can have different symbols in non-English versions of Excel. These will be supported in a later version of Spreadsheet::WriteExcel. European users of Excel take note:. The following table lists all of the core functions supported by Excel 5 and Spreadsheet::WriteExcel. Any additional functions that are available through the "Analysis ToolPak" or other add-ins are not supported.

These functions have all been tested to verify that they work. You can also modify the module to support function names in the following languages: German, French, Spanish, Portuguese, Dutch, Finnish, Italian and Swedish. Writing a large number of formulas with Spreadsheet::WriteExcel can be slow. This is due to the fact that each formula has to be parsed and with the current implementation this is computationally expensive.

In this example the cell reference changes in iterations from A1 to A The parser treats this variable as a token and arranges it according to predefined rules. However, since the parser is oblivious to the value of the token, it is essentially performing the same calculation times.

This is inefficient. The way to avoid this inefficiency and thereby speed up the writing of formulas is to parse the formula once and then repeatedly substitute similar tokens. On an arbitrary test machine this method was 10 times faster than the brute force method shown above. For more information about how Spreadsheet::WriteExcel parses and stores formulas see the Spreadsheet::WriteExcel::Formula man page.

It should be noted however that the overall speed of direct formula parsing will be improved in a future version. See Spreadsheet::WriteExcel::Examples for a full list of examples. The following is a general example which demonstrates some features of working with multiple worksheets. This example shows how to use a conditional numerical format with colours to indicate if a share price has gone up or down.

The following example converts a tab separated file called tab. txt into an Excel file called tab. NOTE: This is a simple conversion program for illustrative purposes only. For converting a CSV or Tab separated or any other type of delimited text file to Excel I recommend the more rigorous csv2xls program that is part of H.

The following is a description of the example files that are provided in the standard Spreadsheet::WriteExcel distribution. They demonstrate the different features and options of the module. See Spreadsheet::WriteExcel::Examples for more details.

The minimum file size is 6K due to the OLE overhead. The maximum file size is approximately 7MB bytes of BIFF data. pl example in the examples directory of the distro. Note, these aren't strict requirements. However, it is best to install them if possible and they will be installed automatically if you use a tool such as CPAN.

pm or ppm. See the INSTALL or install. Spreadsheet::WriteExcel will work on the majority of Windows, UNIX and Macintosh platforms. Specifically, the module will work on any system where perl packs floats in the 64 bit IEEE format. The float must also be in little-endian format but it will be reversed if necessary. In general, if you don't know whether your system supports a 64 bit IEEE float or not, it probably does.

The file cannot be opened for writing. The directory that you are writing to may be protected or the file may be in use by another program. This is a -w warning. You will see it if you are using Spreadsheet::WriteExcel in an environment where temporary files cannot be created, in which case all data will be stored in memory.

The warning is for information only: it does not affect creation but it will affect the speed of execution for large files. The current OLE implementation only supports a maximum BIFF file of this size. Spreadsheet::WriteExcel requires the Parse::RecDescent module. There are a large number of warnings which relate to badly formed formulas and functions.

See the "FORMULAS AND FUNCTIONS IN EXCEL" section for suggestions on how to avoid these errors. You should also check the formula in Excel to ensure that it is valid. Operating system doesn't support 64 bit IEEE float or it is byte-ordered in a way unknown to WriteExcel.

You may sometimes encounter the following error when trying to open a file in Excel: "file. xls cannot be accessed. The file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding. This error generally means that the Excel file has been corrupted. There are two likely causes of this: the file was FTPed in ASCII mode instead of binary mode or else the file was created with UTF-8 data returned by an XML parser.

See "Warning about XML::Parser and perl 5. The following is some general information about the Excel binary format for anyone who may be interested. Excel data is stored in the "Binary Interchange File Format" BIFF file format.

Daniel Rentz of OpenOffice. Charles Wybble has collected together additional information about the Excel file format. The BIFF data is stored along with other data in an OLE Compound File. This is a structured storage which acts like a file system within a file. A Compound File is comprised of storages and streams which, to follow the file system analogy, are like directories and files. Please note that the provision of this information does not constitute an invitation to start hacking at the BIFF or OLE file formats.

There are more interesting ways to waste your time. Depending on your requirements, background and general sensibilities you may prefer one of the following methods of getting data into Excel:. This requires a Windows platform and an installed copy of Excel. This is the most powerful and complete method for interfacing with Excel. If the file extension is csv , Excel will open and convert this format automatically. Generating a valid CSV file isn't as easy as it seems.

Excel files contain an internal index table that allows them to act like a database file. Using one of the standard Perl database modules you can connect to an Excel file as a database. This module allows you to create an Excel XML file using the same interface as Spreadsheet::WriteExcel. This module allows you to create an Excel file from an XML template in a manner similar to HTML::Template. This module allows you to turn a simple XML file into an Excel file using Spreadsheet::WriteExcel as a back-end.

This uses the OLE::Storage-Lite module to extract data from an Excel file. This is a Perl interface to OLE file formats. This has been superseded by the Spreadsheet::ParseExcel module. An Excel file is a binary file within a binary file. It contains several interlinked checksums and changing even one byte can cause it to become corrupted. As such you cannot simply append or update an Excel file.

The only way to achieve this is to read the entire file into memory, make the required changes or additions and then write the file out again.

You can read and rewrite an Excel file using the Spreadsheet::ParseExcel::SaveParser module which is a wrapper around Spreadsheet::ParseExcel and Spreadsheet::WriteExcel. However, you can only rewrite the features that Spreadsheet::WriteExcel supports so macros, graphs and some other features in the original Excel file will be lost.

Also, formulas aren't rewritten, only the result of a formula is written. You must be careful when using Spreadsheet::WriteExcel in conjunction with perl 5. When UTF-8 strings are added to Spreadsheet::WriteExcel's internal data it causes the generated Excel file to become corrupt. Note, this doesn't affect perl 5. To avoid this problem you should upgrade to perl 5. If you have Office Service Pack 3 SP3 installed you may see the following warning when you open a file created by Spreadsheet::WriteExcel:.

SP3 changed Excel's default behaviour when it encounters multiple data in a cell so that it issues a warning when the file is opened and it displays the first data that was written.

Prior to SP3 it didn't issue a warning and displayed the last data written. XML and UTF-8 data on perl 5. The current workaround is to use separate formats for merged and non-merged cell. Nested formulas sometimes aren't parsed correctly and give a result of " VALUE". If you come across a formula that parses like this, let me know. Spreadsheet::ParseExcel: All formulas created by Spreadsheet::WriteExcel are read as having a value of zero. This is because Spreadsheet::WriteExcel only stores the formula and not the calculated result.

Spreadsheet::WriteExcel is in maintenance only mode and has effectively been superseded by Excel::Writer::XLSX. Excel::Writer::XLSX is an API compatible, drop-in replacement for Spreadsheet::WriteExcel. It also has many more features such as conditional formats, better charts, better formula handling, Excel tables and even sparklines.

To convert your Spreadsheet::WriteExcel program to Excel::Writer::XLSX you only need do the following:. However, you can leave them unchanged if required. The Excel::Writer::XLSX module uses more memory by default but has a optimisation mode to reduce usage for large files.

and 1 contributors. VERSION This document refers to version 2. SYNOPSIS To write a string, a formatted string, a number and a formula to the first worksheet in an Excel workbook called perl. The file produced by this module is compatible with Excel 97, , , and QUICK START Spreadsheet::WriteExcel tries to provide an interface to as many of Excel's features as possible.

So for those of you who prefer to assemble Ikea furniture first and then read the instructions, here are three easy steps: 1. Create a new Excel workbook i. file using new. Write to the worksheet using write. new A new Excel workbook is created using the new constructor which accepts either a filename or a filehandle as a parameter. See also, the cgi. For example here is a way to write an Excel file to a scalar with perl 5.

Remember to binmode the output filehandle before printing it. It defines the type of chart that will be created. Insert the chart into the a worksheet. close In general your Excel file will be closed automatically when your program ends or when the Workbook object goes out of scope, however the close method can be used to explicitly close an Excel file. Situations where this can occur are: If my was not used to declare the scope of a workbook variable created using new.

For convenience it is possible to pass either a hash or hash ref of arguments to this method. See also the properties. pl program in the examples dir of the distro. Note: This currently a beta feature. More documentation and examples will be added.

This will generate a warning if the module cannot create the required temporary files:! For example: 0, 0 The top left cell in row-column notation. The write methods return: 0 for success.

To get around this you can use the Excel text format : Format as a string. The following is a simple example showing how to write some Unicode strings in UTFBE format:! sss This conforms to an ISO date but it should be noted that the full range of ISO formats are not supported. sss Standard format yyyy-mm-ddT No time Thh:mm:ss. sss No date yyyy-mm-ddThh:mm:ss. sssZ Additional Z but not time zones yyyy-mm-ddThh:mm:ss No fractional seconds yyyy-mm-ddThh:mm No seconds Note that the T is required in all cases.

org' ; There are two local URIs supported: internal: and external:. xls Sheet2! xls' ; All of the these URI types are recognised by the write method, see above. xls' ; See also, the note about "Cell notation".

xls' ; This method is generally only required when used in conjunction with merged cells. There is no way to force this behaviour through the write method. See also, the note about "Cell notation". The return value of this method is a scalar that can be thought of as a reference to a formula. Option: author This option is used to indicate who the author of the comment is.

Option: visible This option is used to make a cell comment visible when the worksheet is opened. Then if you call write with an appropriate string it will be handled automatically: Writes It would normally be written as a number; 0. bmp', 32, 10 ; The default width of a cell is 63 pixels.

bmp', 0, 0, 2, 0. The default active worksheet is the first worksheet. The default value is the first worksheet. Cell D4.

Cells D4 to G7. Cells G7 to D4. The default cell selections is 0, 0 , 'A1'. The default settings for all of these parameters correspond to Excel's default parameters. PAGE SET-UP METHODS Page set-up methods affect the way that a worksheet looks when it is printed. An Excel worksheet looks something like the following; A B C D Creating and using a Format object Cell formatting is defined through a Format object.

See also "COLOURS IN EXCEL". This format is currently not very useful. Other currencies may require the use of Unicode. The colour format should have one of the following values: [Black] [Blue] [Cyan] [Green] [Magenta] [Red] [White] [Yellow] Alternatively you can specify the colour based on a colour index as follows: [Color n] , where n is a standard Excel colour index - 7. You should ensure that the format string is valid in Excel prior to using it in WriteExcel.

Excel's built-in formats are shown in the following table: Index Index Format String 0 0x00 General 1 0x01 0 2 0x02 0. For further examples see the 'Alignment' worksheet created by formats. This indicates text where the letters run from top to bottom. For further examples see the 'Patterns' worksheet created by formats.

Note: this is not a copy constructor, both objects must exist prior to copying. UNICODE IN EXCEL The following is a brief introduction to handling Unicode in Spreadsheet::WriteExcel. No further intervention is required from the programmer, for example: perl 5. Since the majority of CPAN modules default to UTFBE big-endian Spreadsheet::WriteExcel also uses UTFBE and converts it internally to UTFLE : perl 5. COLOURS IN EXCEL Excel provides a colour palette of 56 colours.

Writes a string not a date. Here is an example:! OUTLINES AND GROUPING IN EXCEL Excel allows you to group rows or columns so that they can be hidden or displayed with a single mouse click.

Outlines can reduce complex data down to a few salient sub-totals or summaries. Clicking on the minus sign on the level 1 outline will collapse the remaining rows as follows: 1 2 3 A B C D Allowable values are: any integer decimal list date time length custom any is used to specify that the type of data is unrestricted. There are 3 options: 'stop' 'warning' 'information' The default is 'stop'.

Limiting input to an integer greater than a fixed value. Limiting input to a decimal in a fixed range. Limiting input to a value in a dropdown list. Limiting input to a date in a fixed range. Displaying a message when the cell is selected. ROW HEIGHTS AND WORKSHEET OBJECTS The following relates to worksheet objects such as images, comments and charts.

FORMULAS AND FUNCTIONS IN EXCEL Caveats The first thing to note is that there are still some outstanding issues with the implementation of formulas and functions: 1. Writing a formula is much slower than writing the equivalent string.

You cannot use array constants, i. Unary minus isn't supported. Whitespace is not preserved around operators. Array formulas are not supported. Introduction The following is a brief introduction to formulas and functions in Excel and Spreadsheet::WriteExcel.

A1} The sheet reference and the cell reference are separated by! If your formula doesn't work in Spreadsheet::WriteExcel try the following: 1. Verify that the formula works in Excel or Gnumeric or OpenOffice. Ensure that it isn't on the Caveats list shown above. Ensure that cell references and formula names are in uppercase. Ensure that you are using ':' as the range operator, A1:A4. Ensure that you are using ',' as the union operator, SUM 1,2,3.

Ensure that the function is in the above table. If you go through steps and you still have a problem, mail me. Improving performance when working with formulas Writing a large number of formulas with Spreadsheet::WriteExcel can be slow.

EXAMPLES See Spreadsheet::WriteExcel::Examples for a full list of examples. Example 1 The following example shows some of the basic features of Spreadsheet::WriteExcel. This is an example of a conditional format. The number is formatted as a percentage. If it is positive it is formatted in green, if it is negative it is formatted in red and if it is zero it is formatted as the default font colour in this case black. Note: the [Green] format produces an unappealing lime green. Try [Color 10] instead for a dark green.

原创 Js逆向教程FuckJs 我们的目的为了让js代码运行起来。可以不需要解密，将代码扣出来运行就可以。任何一个js类型的变量结果 加上一个字符串 ，只会变成字符串。所以这个调试起来很麻烦 只能单步调试 还是用解密工具解密。通过这种特性 可以组合成各种各样的加密方式。这个的原理就是将各种字符串加起来。2个值通过 运算会变成0或者1. jsfuck有对应的解密工具及。我们这里只是讲解js的混淆机制。可以看到只有这3种字符。 原创 Js逆向教程常见混淆AA和JJ js默认 支持Unicode的。所以支持所有的国家语种。有没有哪些国家的和O很像但不是O,和0很像但不是0,和p很像但不是p所以可以用这个相近的符号进行代码混淆。 原创 Js逆向教程常见代码混淆 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程常见的加密方式 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程跟值技巧 一般不会出现在jquery成熟的第3仓库里面。jquery是封装好的成熟的第3仓库，一般不会去修改它。因为如果jquery版本提升了，还要去改jquery。 原创 Js逆向教程方法栈 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程js逆向断点的种类及介绍 能修改输出js运行当中的一些变量的值能下断点批量监听一些变量值当渲染时，样式发生改变，会触发DOM断点它一般在 用户触发了某个事件 时，段下来。执行的比较考前，距离加密函数比较远。所以无法根据栈去快速定位。它的优点时定位的比较准。清空Dom断点最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程明确js逆向的目标 通过本地运行js代码那 实现脱离浏览器后 能够实现和浏览器上运行加密js的效果。网站上完全都是JavaScript实现的加密，我们的目的要知道加密的整个过程，并且实现这个加密的过程，拿到和浏览器一样的加密的结果。得到加密的结果之后就可以跳过浏览器，本地直接给服务器发送加密数据，从而直接获取服务器响应的结果。 原创 Js逆向教程浏览器调试工具-Application页面 本地网站应用缓存页面。 原创 Js逆向教程浏览器调试工具-Source面板 切换到source面板，对于source面板，需要打开搜索面板才能发挥出完整的功能。 原创 Js逆向教程浏览器调试工具-Network面板 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程浏览器调试工具-可视化的Elements 页面中有很多事件，比如说鼠标按下，滚动条滑动。最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 python一招自动搞定Chromedriver爬虫驱动的更新 日常的web自动化过程中，我们常常用python selenium库来操纵Chrome浏览器实现网页的自动化。这其中有个比较头疼的问题：Chrome的更新频率非常频繁，与之对应的Chromedriver版本也必须相应更新。如果两者版本的主版本号相差超过1，selenium则会报异常.

那有没有好的办法解决这个问题呢？方法当然有，首先我们需要知道哪里可以下载到不同版本的文件。这里推荐两个网站，国内首选淘宝的镜像仓库：数据更新会比谷歌官方稍慢；可供下载的版本有时不全； 原创 如何安装MockingBird-AI拟声: 5秒内克隆您的声音并生成任意语音内容 作者：虚坏叔叔早餐店不会开到晚上，想吃的人早就来了！😄。 原创 Quasar — 免费开源的Windows远程管理工具 适用于Windows的免费开源远程控制管理工具Quasar是一种用C＃编码的快速轻量级远程管理工具。可用于管理工作到员工监控等。Quasar提供高稳定性和易用的用户界面，是您理想的远程控制管理解决方案。 原创 AutoJs4. 原创 将你的 Python 脚本转换为命令行程序 哈喽，大家好，今天给大家介绍一下，如何通过Python自动整理文件。 原创 如何通过Python自动整理文件？ 哈喽，大家好，今天给大家介绍一下，如何通过Python自动整理文件。 原创 如何用python自动化微信小程序 本文介绍了整个微信小程序的自动化过程。我已经将全部源码上传到后台上，关注文章底部公众号后回复「kja」即可获得。你的肯定是我最大的鼓励和支持。 2.
