1066           REPORTING A BUG OR ASKING A QUESTION
1067
1068               Feel free to report bugs or ask questions. However, to save time
1069               consider the following steps first:
1070
1071               Read the documentation:
1072
1073                   The Spreadsheet::WriteExcel documentation has been refined in
1074                   response to user questions. Therefore, if you have a question it is
1075                   possible that someone else has asked it before you and that it is
1076                   already addressed in the documentation. Since there is a lot of
1077                   documentation to get through you should at least read the table of
1078                   contents and search for keywords that you are interested in.
1079
1080               Look at the example programs:
1081
1082                   There are over 70 example programs shipped with the standard
1083                   Spreadsheet::WriteExcel distribution. Many of these were created in
1084                   response to user questions. Try to identify an example program that
1085                   corresponds to your query and adapt it to your needs.
1086
1087           HINTS_1
1088           print "Press enter ..."; <STDIN>;
1089
1090           print << 'HINTS_2';
1091
1092               If you submit a bug report here are some pointers.
1093
1094               1.  Put "WriteExcel:" at the beginning of the subject line. This helps
1095                   to filter genuine messages from spam.
1096
1097               2.  Describe the problems as clearly and as concisely as possible.
1098
1099               3.  Send a sample program. It is often easier to describe a problem in
1100                   code than in written prose.
1101
1102               4.  The sample program should be as small as possible to demonstrate the
1103                   problem. Don't copy and past large sections of your program. The
1104                   program should also be self contained and working.
1105
1106               A sample bug report is generated below. If you use this format then it
1107               will help to analyse your question and respond to it more quickly.
1108
1109               Please don't send patches without contacting the author first.

1121           Subject: WriteExcel: Problem with something.
1122
1123           Hi John,
1124
1125           I am using Spreadsheet::WriteExcel and I have encountered a problem. I
1126           want it to do SOMETHING but the module appears to do SOMETHING_ELSE.
1127
1128           Here is some code that demonstrates the problem.
1129
1130               #!/usr/bin/perl -w

1132               use strict;

1135               my $workbook  = Spreadsheet::WriteExcel->new("reload.xls");
1136               my $worksheet = $workbook->add_worksheet();
1137
1138               $worksheet->write(0, 0, "Hi Excel!");

1478   Example: autofit.pl
1479       Simulate Excel's autofit for column widths.
1480
1481       Excel provides a function called Autofit (Format->Columns->Autofit)
1482       that adjusts column widths to match the length of the longest string in
1483       a column.  Excel calculates these widths at run time when it has access
1484       to information about string lengths and font information. This function
1485       is *not* a feature of the file format and thus cannot be implemented by
1486       Spreadsheet::WriteExcel.
1487
1488       However, we can make an attempt to simulate it by keeping track of the
1489       longest string written to each column and then adjusting the column
1490       widths prior to closing the file.
1491
1492       We keep track of the longest strings by adding a handler to the write()
1493       function. See add_handler() in the S::WE docs for more information.
1494
1495       The main problem with trying to simulate Autofit lies in defining a
1496       relationship between a string length and its width in a arbitrary font
1497       and size. We use two approaches below. The first is a simple direct
1498       relationship obtained by trial and error. The second is a slightly more
1499       sophisticated method using an external module. For more complicated
1500       applications you will probably have to work out your own methods.

2734   Example: chess.pl
2735       Example of formatting using the Spreadsheet::WriteExcel module via
2736       property hashes.
2737
2738       Setting format properties via hashes of values is useful when you have
2739       to deal with a large number of similar formats. Consider for example a
2740       chess board pattern with black squares, white unformatted squares and a
2741       border.
2742
2743       This relatively simple example requires 14 separate Format objects
2744       although there are only 5 different properties: black background, top
2745       border, bottom border, left border and right border.
2746
2747       Using property hashes it is possible to define these 5 sets of
2748       properties and then add them together to create the 14 Format
2749       configurations.

5417       Example of how use Spreadsheet::WriteExcel to generate Excel outlines
5418       and grouping.
5419
5420       Excel allows you to group rows or columns so that they can be hidden or
5421       displayed with a single mouse click. This feature is referred to as
5422       outlines.
5423
5424       Outlines can reduce complex data down to a few salient sub-totals or
5425       summaries.
5426
5427       This feature is best viewed in Excel but the following is an ASCII
5428       representation of what a worksheet with three outlines might look like.
5429       Rows 3-4 and rows 7-8 are grouped at level 2. Rows 2-9 are grouped at
5430       level 1. The lines at the left hand side are called outline level bars.
5431

5445
5446       Clicking the minus sign on each of the level 2 outlines will collapse
5447       and hide the data as shown in the next figure. The minus sign changes
5448       to a plus sign to indicate that the data in the outline is hidden.

6277   Example: row_wrap.pl
6278       Demonstrates how to wrap data from one worksheet onto another.
6279
6280       Excel has a row limit of 65536 rows. Sometimes the amount of row data
6281       to be written to a file is greater than this limit. In this case it is
6282       a useful technique to wrap the data from one worksheet onto the next so
6283       that we get something like the following:

6731   Example: textwrap.pl
6732       Example of formatting using the Spreadsheet::WriteExcel module
6733
6734       This example shows how to wrap text in a cell. There are two
6735       alternatives, vertical justification and text wrap.
6736
6737       With vertical justification the text is wrapped automatically to fit
6738       the column width. With text wrap you must specify a newline with an
6739       embedded \n.

8112
8113       Simple program to convert a CSV comma-separated value file to an Excel
8114       file.  This is more or less an non-op since Excel can read CSV files.
8115       The program uses Text::CSV_XS to parse the CSV.
8116
8117       Usage: csv2xls.pl file.csv newfile.xls
8118
8119       NOTE: This is only a simple conversion utility for illustrative
8120       purposes.  For converting a CSV or Tab separated or any other type of
8121       delimited text file to Excel I recommend the more rigorous csv2xls
8122       program that is part of H.Merijn Brand's Text::CSV_XS module distro.

8269   Example: datecalc1.pl
8270       NOTE: An easier way of writing dates and times is to use the newer

8272
8273       Demonstration of writing date/time cells to Excel spreadsheets, using
8274       UNIX/Perl time as source of date/time.
8275
8276       UNIX/Perl time is the time since the Epoch (00:00:00 GMT, 1 Jan 1970)
8277       measured in seconds.
8278
8279       An Excel file can use exactly one of two different date/time systems.
8280       In these systems, a floating point number represents the number of days
8281       (and fractional parts of the day) since a start point. The floating
8282       point number is referred to as a 'serial'.
8283
8284       The two systems ('1900' and '1904') use different starting points:
8285
8286        '1900'; '1.00' is 1 Jan 1900 BUT 1900 is erroneously regarded as
8287                a leap year - see:
8288                  http://support.microsoft.com/support/kb/articles/Q181/3/70.asp
8289                for the excuse^H^H^H^H^H^Hreason.
8290        '1904'; '1.00' is 2 Jan 1904.
8291
8292       The '1904' system is the default for Apple Macs. Windows versions of
8293       Excel have the option to use the '1904' system.
8294
8295       Note that Visual Basic's "DateSerial" function does NOT erroneously
8296       regard 1900 as a leap year, and thus its serials do not agree with the
8297       1900 serials of Excel for dates before 1 Mar 1900.
8298
8299       Note that StarOffice (at least at version 5.2) does NOT erroneously
8300       regard 1900 as a leap year, and thus its serials do not agree with the
8301       1900 serials of Excel for dates before 1 Mar 1900.

8931           =head1 DESCRIPTION
8932
8933
8934           This program takes an MS Excel workbook file as input and from
8935           that file, produces an output file with Perl code that uses the
8936           Spreadsheet::WriteExcel module to reproduce the original
8937           file.
8938

8940           =head1 STUFF
8941
8942
8943           Additional hands-on editing of the output file might be neccecary
8944           as:
8945
8946
8947           * This program always names the file produced by output script
8948             _change_me_.xls
8949
8950
8951           * Users of international Excel versions will have som work to do
8952             on list separators and numeric punctation characters.
