To write a string, a formatted string, a number and a formula to the first worksheet in an Excel workbook called perl. The Spreadsheet::WriteExcel Perl module can be used to create a cross-platform Excel binary file. Multiple worksheets can be added to a workbook and formatting can be applied to cells. Text, numbers, formulas, hyperlinks, images and charts can be written to the cells. The module will work on the majority of Windows, UNIX and Mac platforms.

This module cannot be used to write to an existing Excel file See "MODIFYING AND REWRITING EXCEL FILES". Note: This module is in maintenance only mode and in future will only be updated with bug fixes.

The newer, more feature rich and API compatible Excel::Writer::XLSX module is recommended instead. See, "Migrating to Excel::Writer::XLSX".

Spreadsheet::WriteExcel tries to provide an interface to as many of Excel's features as possible. As a result there is a lot of documentation to accompany the interface and it can be difficult at first glance to see what it important and what is not.

So for those of you who prefer to assemble Ikea furniture first and then read the instructions, here are three easy steps:. This will create an Excel file called perl. xls with a single worksheet and the text 'Hi Excel! And that's it. Okay, so there is actually a zeroth step as well, but use module goes without saying. There are also more than 80 examples that come with the distribution and which you can use to get you started.

See "EXAMPLES". Those of you who read the instructions first and assemble the furniture afterwards will know how to proceed. The Spreadsheet::WriteExcel module provides an object oriented interface to a new Excel workbook. The following methods are available through a new workbook. If you are unfamiliar with object oriented interfaces or the way that they are implemented in Perl have a look at perlobj and perltoot in the main Perl documentation.

A new Excel workbook is created using the new constructor which accepts either a filename or a filehandle as a parameter. The following example creates a new Excel file based on a filename:.

The new constructor returns a Spreadsheet::WriteExcel object that you can use to add worksheets and store data. It should be noted that although my is not specifically required it defines the scope of the new workbook variable and, in the majority of cases, ensures that the workbook is closed properly without explicitly calling the close method. If the file cannot be created, due to file permissions or some other reason, new will return undef.

Therefore, it is good practice to check the return value of new before proceeding. will be set if there is a file creation error. You can also pass a valid filehandle to the new constructor.

For example in a CGI program you could do something like this:. pl programs in the examples directory of the distro. Filehandles can also be useful if you want to stream an Excel file over a socket or if you want to store an Excel file in a scalar.

pl and filehandle. Note about the requirement for binmode. An Excel file is comprised of binary data. Therefore, if you are using a filehandle you should ensure that you binmode it prior to passing it to new. You should do this regardless of whether you are on a Windows platform or not. This applies especially to users of perl 5. If your program, either intentionally or not, writes UTF-8 data to a filehandle that is passed to new it will corrupt the Excel file that is created.

You don't have to worry about binmode if you are using filenames instead of filehandles. Spreadsheet::WriteExcel performs the binmode internally when it converts the filename to a filehandle. For more information about binmode see perlfunc and perlopentut in the main Perl documentation. At least one worksheet should be added to a new workbook. A worksheet is used to write data into cells:. Sheet1, Sheet2, etc. The worksheet name must be a valid Excel worksheet name, i. On systems with perl 5.

On earlier Perl systems your can specify UTFBE worksheet names using an additional optional parameter:. You can either define the properties at creation time via a hash of property values or later via method calls. Set the name for the chart sheet. The name property is optional and if it isn't supplied will default to Chart The name must be a valid Excel worksheet name.

The name property can be omitted for embedded charts. It is an error to try insert a Chart that doesn't have this flag set. See Spreadsheet::WriteExcel::Chart for details on how to configure the chart object once it is created. txt or. 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.

An explicit close is required if the file must be closed prior to performing some external action on it such as copying it, reading its size or attaching it to an email. In addition, close may be required to prevent perl's garbage collector from disposing of the Workbook, Worksheet and Format objects in the wrong order.

Situations where this can occur are:. If my was not used to declare the scope of a workbook variable created using new. The reason for this is that Spreadsheet::WriteExcel relies on Perl's DESTROY mechanism to trigger destructor methods in a specific sequence. This may not happen in cases where the Workbook, Worksheet and Format variables are not lexically scoped or where they have different lexical scopes.

In general, if you create a file with a size of 0 bytes or you fail to create a file you need to call close. The return value of close is the same as that returned by perl when it closes the file created by new.

This allows you to handle error conditions in the usual way:. This method is used to improve compatibility with third party applications that read Excel files. An Excel file is comprised of binary records that describe properties of a spreadsheet. Excel is reasonably liberal about this and, outside of a core subset, it doesn't require every possible record to be present when it reads a file. This is also true of Gnumeric and OpenOffice.

Org Calc. Spreadsheet::WriteExcel takes advantage of this fact to omit some records in order to minimise the amount of data stored in memory and to simplify and speed up the writing of files. However, some third party applications that read Excel files often expect certain records to be present.

In "compatibility mode" Spreadsheet::WriteExcel writes these records and tries to be as close to an Excel generated file as possible. In perl 5. See "UNICODE IN EXCEL". Usually Spreadsheet::WriteExcel allows you to use UTF with pre 5. However, document properties don't support UTF for these type of strings.

In order to promote the usefulness of Perl and the Spreadsheet::WriteExcel module consider adding a comment such as the following when using document properties:. However, this also means that the resulting OLE document may possibly be buggy for files less than 7MB since it hasn't been as rigorously tested in that domain. This is being investigated. If you encounter any problems with this features let me know.

This method is used to defined a name that can be used to represent a value, a single cell or a range of cells in a workbook. For speed and efficiency Spreadsheet::WriteExcel stores worksheet data in temporary files prior to assembling the final workbook. If Spreadsheet::WriteExcel is unable to create these temporary files it will store the required data in memory. This can be slow for large files. The problem occurs mainly with IIS on Windows although it could feasibly occur on Unix systems as well.

To check if this might be a problem on a particular system you can run a simple test program with -w or use warnings. This will generate a warning if the module cannot create the required temporary files:.

The File::Temp module is used to create the temporary files. You can find out which directory is used on your system as follows:. Even if the default temporary file directory is accessible you may wish to specify an alternative location for security or maintenance reasons:. This means that a single program running on one of these systems will be limited to creating a total of workbook and worksheet objects.

You can run multiple, non-concurrent programs to work around this if necessary. A new colour is set using its RGB red green blue components. The sheets method returns a list, or a sliced list, of the worksheets in a workbook. If no arguments are passed the method returns a list of all the worksheets in the workbook. This is useful if you want to repeat an operation on each worksheet:.

InfoWorld First Look: Supercalc 4 challenging with new tactic. However it contains a bug. This method can be used to divide a worksheet into horizontal or vertical regions known as panes and to also "freeze" these panes so that the splitter bars are not visible.
