 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.

 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";

=head2 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.

=head2 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 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.

=head2 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.

    #
    # 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   |  ...

=head2 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.

=head2 Example: csv2xls.pl

Example of how to use the WriteExcel module

Simple program to convert a CSV comma-separated value file to an Excel file.
This is more or less an non-op since Excel can read CSV files.
The program uses Text::CSV_XS to parse the CSV.

Usage: csv2xls.pl file.csv newfile.xls

NOTE: This is only a simple conversion utility for illustrative purposes.
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

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.

 # Calculation description
 # =======================
 #
 # 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)
 # were leap years with an extra day.
 # Thus there were 17 + 70*365 days = 25567 days between 1 Jan 1900 and
 # 1 Jan 1970.
 # In the 1900 system, '1' is 1 Jan 1900, but as 1900 was not a leap year
 # 1 Jan 1900 should really be '2', so 1 Jan 1970 is '25569'.
 #
 # 1904 system
 # -----------
 # 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...

=head2 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.
