    REPORTING A BUG OR ASKING A QUESTION

        Feel free to report bugs or ask questions. However, to save time
        consider the following steps first:

        Read the documentation:

            The Spreadsheet::WriteExcel documentation has been refined in
            response to user questions. Therefore, if you have a question it is
            possible that someone else has asked it before you and that it is
            already addressed in the documentation. Since there is a lot of
            documentation to get through you should at least read the table of
            contents and search for keywords that you are interested in.

        Look at the example programs:

            There are over 70 example programs shipped with the standard
            Spreadsheet::WriteExcel distribution. Many of these were created in
            response to user questions. Try to identify an example program that
            corresponds to your query and adapt it to your needs.

    HINTS_1
    print "Press enter ..."; <STDIN>;

    print << 'HINTS_2';

        If you submit a bug report here are some pointers.

        1.  Put "WriteExcel:" at the beginning of the subject line. This helps
            to filter genuine messages from spam.

        2.  Describe the problems as clearly and as concisely as possible.

        3.  Send a sample program. It is often easier to describe a problem in
            code than in written prose.

        4.  The sample program should be as small as possible to demonstrate the
            problem. Don't copy and past large sections of your program. The
            program should also be self contained and working.

        A sample bug report is generated below. If you use this format then it
        will help to analyse your question and respond to it more quickly.

        Please don't send patches without contacting the author first.

    HINTS_2

    To:      John McNamara <jmcnamara@cpan.org>
    Subject: WriteExcel: Problem with something.

    Hi John,

    I am using Spreadsheet::WriteExcel and I have encountered a problem. I
    want it to do SOMETHING but the module appears to do SOMETHING_ELSE.

    Here is some code that demonstrates the problem.

        #!/usr/bin/perl -w

        use strict;
        use Spreadsheet::WriteExcel;

        my $workbook  = Spreadsheet::WriteExcel->new("reload.xls");
        my $worksheet = $workbook->add_worksheet();

        $worksheet->write(0, 0, "Hi Excel!");

        __END__

    I tested using Excel XX (or Gnumeric or OpenOffice.org).

    My automatically generated system details are as follows:
    EMAIL

    print "\n    Perl version   : $]";
    print "\n    OS name        : $^O";
    print "\n    Module versions: (not all are required)\n";

    my @modules = qw(
                      Spreadsheet::WriteExcel
                      Spreadsheet::ParseExcel
                      OLE::Storage_Lite
                      Parse::RecDescent
                      File::Temp
                      Digest::MD4
                      Digest::Perl::MD4
                      Digest::MD5
                    );

    for my $module (@modules) {
        my $version;
        eval "require $module";

        if (not $@) {
            $version = $module->VERSION;
            $version = '(unknown)' if not defined $version;
        }
        else {
            $version = '(not installed)';
        }

        printf "%21s%-24s\t%s\n", "", $module, $version;
    }

    print << "BYE";

  Example: autofit.pl
Simulate Excel's autofit for column widths.

Excel provides a function called Autofit (Format->Columns->Autofit) that adjusts column widths to match the length of the longest string in a column. Excel calculates these widths at run time when it has access to information about string lengths and font information. This function is *not* a feature of the file format and thus cannot be implemented by Spreadsheet::WriteExcel.

However, we can make an attempt to simulate it by keeping track of the longest string written to each column and then adjusting the column widths prior to closing the file.

We keep track of the longest strings by adding a handler to the write() function. See add_handler() in the S::WE docs for more information.

The main problem with trying to simulate Autofit lies in defining a relationship between a string length and its width in a arbitrary font and size. We use two approaches below. The first is a simple direct relationship obtained by trial and error. The second is a slightly more sophisticated method using an external module. For more complicated applications you will probably have to work out your own methods.

  Example: chess.pl
Example of formatting using the Spreadsheet::WriteExcel module via property hashes.

Setting format properties via hashes of values is useful when you have to deal with a large number of similar formats. Consider for example a chess board pattern with black squares, white unformatted squares and a border.

This relatively simple example requires 14 separate Format objects although there are only 5 different properties: black background, top border, bottom border, left border and right border.

Using property hashes it is possible to define these 5 sets of properties and then add them together to create the 14 Format configurations.

  Example: merge2.pl
Simple example of merging cells using the Spreadsheet::WriteExcel module

This example merges three cells using the "Centre Across Selection" alignment which was the Excel 5 method of achieving a merge. For a more modern approach use the merge_range() worksheet method instead. See the merge3.pl - merge6.pl programs.

Example of how to use the Spreadsheet::WriteExcel module to send an Excel file to a browser using mod_perl 1 and Apache

This module ties *XLS directly to Apache, and with the correct content-disposition/types it will prompt the user to save the file, or open it at this location.

This script is a modification of the Spreadsheet::WriteExcel cgi.pl example.

Change the name of this file to Cgi.pm. Change the package location to where ever you locate this package. In the example below it is located in the WriteExcel directory.

Your httpd.conf entry for this module, should you choose to use it as a stand alone app, should look similar to the following:

    <Location /spreadsheet-test>
      SetHandler perl-script
      PerlHandler Spreadsheet::WriteExcel::Cgi
      PerlSendHeader On
    </Location>

The PerlHandler name above and the package name below *have* to match.

  Example: mod_perl2.pl
Example of how to use the Spreadsheet::WriteExcel module to send an Excel file to a browser using mod_perl 2 and Apache.

This module ties *XLS directly to Apache, and with the correct content-disposition/types it will prompt the user to save the file, or open it at this location.

This script is a modification of the Spreadsheet::WriteExcel cgi.pl example.

Change the name of this file to MP2Test.pm. Change the package location to where ever you locate this package. In the example below it is located in the WriteExcel directory.

Your httpd.conf entry for this module, should you choose to use it as a stand alone app, should look similar to the following:

    PerlModule Apache2::RequestRec
    PerlModule APR::Table
    PerlModule Apache2::RequestIO

    <Location /spreadsheet-test>
       SetHandler perl-script
       PerlResponseHandler Spreadsheet::WriteExcel::MP2Test
    </Location>

The PerlResponseHandler must match the package name below.

  Example: outline.pl
Example of how use Spreadsheet::WriteExcel to generate Excel outlines and grouping.

Excel allows you to group rows or columns so that they can be hidden or displayed with a single mouse click. This feature is referred to as outlines.

Outlines can reduce complex data down to a few salient sub-totals or summaries.

This feature is best viewed in Excel but the following is an ASCII representation of what a worksheet with three outlines might look like. Rows 3-4 and rows 7-8 are grouped at level 2. Rows 2-9 are grouped at level 1. The lines at the left hand side are called outline level bars.

            ------------------------------------------
     1 2 3 |   |   A   |   B   |   C   |   D   |  ...
            ------------------------------------------
      _    | 1 |   A   |       |       |       |  ...
     |  _  | 2 |   B   |       |       |       |  ...
     | |   | 3 |  (C)  |       |       |       |  ...
     | |   | 4 |  (D)  |       |       |       |  ...
     | -   | 5 |   E   |       |       |       |  ...
     |  _  | 6 |   F   |       |       |       |  ...
     | |   | 7 |  (G)  |       |       |       |  ...
     | |   | 8 |  (H)  |       |       |       |  ...
     | -   | 9 |   I   |       |       |       |  ...
     -     | . |  ...  |  ...  |  ...  |  ...  |  ...

Clicking the minus sign on each of the level 2 outlines will collapse and hide the data as shown in the next figure. The minus sign changes to a plus sign to indicate that the data in the outline is hidden.

            ------------------------------------------
     1 2 3 |   |   A   |   B   |   C   |   D   |  ...
            ------------------------------------------
      _    | 1 |   A   |       |       |       |  ...
     |     | 2 |   B   |       |       |       |  ...
     | +   | 5 |   E   |       |       |       |  ...
     |     | 6 |   F   |       |       |       |  ...
     | +   | 9 |   I   |       |       |       |  ...
     -     | . |  ...  |  ...  |  ...  |  ...  |  ...

Clicking on the minus sign on the level 1 outline will collapse the remaining rows as follows:

            ------------------------------------------
     1 2 3 |   |   A   |   B   |   C   |   D   |  ...
            ------------------------------------------
           | 1 |   A   |       |       |       |  ...
     +     | . |  ...  |  ...  |  ...  |  ...  |  ...

  Example: row_wrap.pl
Demonstrates how to wrap data from one worksheet onto another.

Excel has a row limit of 65536 rows. Sometimes the amount of row data to be written to a file is greater than this limit. In this case it is a useful technique to wrap the data from one worksheet onto the next so that we get something like the following:

  Sheet1  Row     1  -  65536
  Sheet2  Row 65537  - 131072
  Sheet3  Row 131073 - ...

In order to achieve this we use a single worksheet reference and reinitialise it to point to a new worksheet when required.

  Example: datecalc1.pl
NOTE: An easier way of writing dates and times is to use the newer
      write_date_time() Worksheet method. See the date_time.pl example.

Demonstration of writing date/time cells to Excel spreadsheets, using UNIX/Perl time as source of date/time.

UNIX/Perl time is the time since the Epoch (00:00:00 GMT, 1 Jan 1970) measured in seconds.

An Excel file can use exactly one of two different date/time systems. In these systems, a floating point number represents the number of days (and fractional parts of the day) since a start point. The floating point number is referred to as a 'serial'.

The two systems ('1900' and '1904') use different starting points:

 '1900'; '1.00' is 1 Jan 1900 BUT 1900 is erroneously regarded as
         a leap year - see:
           http://support.microsoft.com/support/kb/articles/Q181/3/70.asp
         for the excuse^H^H^H^H^H^Hreason.
 '1904'; '1.00' is 2 Jan 1904.

The '1904' system is the default for Apple Macs. Windows versions of Excel have the option to use the '1904' system.

Note that Visual Basic's "DateSerial" function does NOT erroneously regard 1900 as a leap year, and thus its serials do not agree with the 1900 serials of Excel for dates before 1 Mar 1900.

Note that StarOffice (at least at version 5.2) does NOT erroneously regard 1900 as a leap year, and thus its serials do not agree with the 1900 serials of Excel for dates before 1 Mar 1900.

    # =======================
    #
    # 1900 system
    # -----------
    # Unix time is '0' at 00:00:00 GMT 1 Jan 1970, i.e. 70 years after 1 Jan 1900.
    # Of those 70 years, 17 (1904,08,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68)

    # In the 1900 system, '1' is 1 Jan 1900, but as 1900 was not a leap year

    # -----------
    # Unix time is '0' at 00:00:00 GMT 1 Jan 1970, i.e. 66 years after 1 Jan 1904.
    # Of those 66 years, 17 (1904,08,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68)
    # were leap years with an extra day.
    # Thus there were 17 + 66*365 days = 24107 days between 1 Jan 1904 and
    # 1 Jan 1970.
    # In the 1904 system, 2 Jan 1904 being '1', 1 Jan 1970 is '24107'.

    =head1 NAME

    lecxe - A Excel file to Spreadsheet::WriteExcel code converter

    =head1 DESCRIPTION

    This program takes an MS Excel workbook file as input and from
    that file, produces an output file with Perl code that uses the
    Spreadsheet::WriteExcel module to reproduce the original
    file.

    =head1 STUFF

    Additional hands-on editing of the output file might be neccecary
    as:

    * This program always names the file produced by output script
      _change_me_.xls

    * Users of international Excel versions will have som work to do
      on list separators and numeric punctation characters.

    =head1 SEE ALSO

    L<Win32::OLE>, L<Win32::OLE::Variant>, L<Spreadsheet::WriteExcel>

    =head1 BUGS

    * Picks wrong color on cells sometimes.

    * Probably a few other...

    =head1 DISCLAIMER

    I do not guarantee B<ANYTHING> with this program. If you use it you
    are doing so B<AT YOUR OWN RISK>! I may or may not support this
    depending on my time schedule...

  Example: writeA1.pl
This is an example of how to extend the Spreadsheet::WriteExcel module.

Code is appended to the Spreadsheet::WriteExcel::Worksheet module by reusing the package name. The new code provides a write() method that allows you to use Excels A1 style cell references. This is not particularly useful but it serves as an example of how the module can be extended without modifying the code directly.
