# ExcelFmt()
#
# This function takes an Excel style number format and converts a number into
# that format. for example: 'hh:mm:ss AM/PM' + 0.01023148 = '12:14:44 AM'.
#
# It does this with a type of templating mechanism. The format string is parsed
# to identify tokens that need to be replaced and their position within the
# string is recorded. These can be thought of as placeholders. The number is
# then converted to the required formats and substituted into the placeholders.
#
# Interested parties should refer to the Excel documentation on cell formats for
# more information: http://office.microsoft.com/en-us/excel/HP051995001033.aspx
# The Microsoft documentation for the Excel Binary File Format, [MS-XLS].pdf,
# also contains a ABNF grammar for number format strings.
#
# Maintainers notes:
# ==================
#
# Note on format subsections:
# A format string can contain 4 possible sub-sections separated by semi-colons:
# Positive numbers, negative numbers, zero values, and text.
# For example: _(* #,##0_);_(* (#,##0);_(* "-"_);_(@_)
#
# Note on conditional formats.
# A number format in Excel can have a conditional expression such as:
# [>9999999](000)000-0000;000-0000
# This is equivalent to the following in Perl:
# $format = $number > 9999999 ? '(000)000-0000' : '000-0000';
# Nested conditionals are also possible but we don't support them.
#
# Efficiency: The excessive use of substr() isn't very efficient. However,
# it probably doesn't merit rewriting this function with a parser or regular
# expressions and \G.
#
# TODO: I think the single quote handling may not be required. Check.

=head1 DESCRIPTION
The C<Spreadsheet::ParseExcel::Utility> module provides utility functions for working with ParseExcel and Excel data.
=head1 Functions
C<Spreadsheet::ParseExcel::Utility> can export the following functions:
ExcelFmt
ExcelLocaltime
LocaltimeExcel
col2int
int2col
sheetRef
xls2csv
These functions must be imported implicitly:
# Just one function.
use Spreadsheet::ParseExcel::Utility 'col2int';
# More than one.
use Spreadsheet::ParseExcel::Utility qw(ExcelFmt ExcelLocaltime LocaltimeExcel);
=head2 ExcelFmt($format_string, $number, $is_1904)
Excel stores data such as dates and currency values as numbers. The way these numbers are displayed is controlled by the number format string for the cell. For example a cell with a number format of C<'$#,##0.00'> for currency and a value of 1234.567 would be displayed as follows:
'$#,##0.00' + 1234.567 = '$1,234.57'.
The C<ExcelFmt()> function tries to emulate this formatting so that the user can convert raw numbers returned by C<Spreadsheet::ParseExel> to a desired format. For example:
print ExcelFmt('$#,##0.00', 1234.567); # $1,234.57.
The syntax of the function is:
my $text = ExcelFmt($format_string, $number, $is_1904);
Where C<$format_string> is an Excel number format string, C<$number> is a real or integer number and C<is_1904> is an optional flag to indicate that dates should use Excel's 1904 epoch instead of the default 1900 epoch.
C<ExcelFmt()> is also used internally to convert numbers returned by the C<Cell::unformatted()> method to the formatted value returned by the C<Cell::value()> method:
my $cell = $worksheet->get_cell( 0, 0 );
print $cell->unformatted(), "\n"; # 1234.567
print $cell->value(), "\n"; # $1,234.57
The most common usage for C<ExcelFmt> is to convert numbers to dates. Dates and times in Excel are represented by real numbers, for example "1 Jan 2001 12:30 PM" is represented by the number 36892.521. The integer part of the number stores the number of days since the epoch and the fractional part stores the percentage of the day. By applying an Excel number format the number is converted to the desired string representation:
print ExcelFmt('d mmm yyyy h:mm AM/PM', 36892.521); # 1 Jan 2001 12:30 PM
C<$is_1904> is an optional flag to indicate that dates should use Excel's 1904 epoch instead of the default 1900 epoch. Excel for Windows generally uses 1900 and Excel for Mac OS uses 1904. The C<$is1904> flag isn't required very often by a casual user and can usually be ignored.
=head2 ExcelLocaltime($excel_datetime, $is_1904)
The C<ExcelLocaltime()> function converts from an Excel date/time number to a C<localtime()>-like array of values:
my @time = ExcelLocaltime($excel_datetime);
# 0 1 2 3 4 5 6 7
my ( $sec, $min, $hour, $day, $month, $year, $wday, $msec ) = @time;
The array elements from C<(0 .. 6)> are the same as Perl's C<localtime()>. The last element C<$msec> is milliseconds. In particular it should be noted that, in common with C<localtime()>, the month is zero indexed and the year is the number of years since 1900. This means that you will usually need to do the following:
$month++;
$year += 1900;
See also Perl's documentation for L<localtime()|perlfunc>:
The C<$is_1904> flag is an optional. It is used to indicate that dates should use Excel's 1904 epoch instead of the default 1900 epoch.
=head2 LocaltimeExcel($sec, $min, $hour, $day, $month, $year, $wday, $msec, $is_1904)
The C<LocaltimeExcel()> function converts from a C<localtime()>-like array of values to an Excel date/time number:
$excel_datetime = LocaltimeExcel($sec, $min, $hour, $day, $month, $year, $wday, $msec);
The array elements from C<(0 .. 6)> are the same as Perl's C<localtime()>. The last element C<$msec> is milliseconds. In particular it should be noted that, in common with C<localtime()>, the month is zero indexed and the year is the number of years since 1900. See also Perl's documentation for L<localtime()|perlfunc>:
The C<$wday> and C<$msec> elements are usually optional. This time elements can also be zeroed if they aren't of interest:
# sec, min, hour, day, month, year
$excel_datetime = LocaltimeExcel( 0, 0, 0, 1, 0, 101 );
print ExcelFmt('d mmm yyyy', $excel_datetime); # 1 Jan 2001
The C<$is_1904> flag is also optional. It is used to indicate that dates should use Excel's 1904 epoch instead of the default 1900 epoch.
=head2 col2int($column)
The C<col2int()> function converts an Excel column letter to an zero-indexed column number:
print col2int('A'); # 0
print col2int('AA'); # 26
This function was contributed by Kevin Mulholland.
=head2 int2col($column_number)
The C<int2col()> function converts an zero-indexed Excel column number to a column letter:
print int2col(0); # 'A'
print int2col(26); # 'AA'
This function was contributed by Kevin Mulholland.
=head2 sheetRef($cell_string)
The C<sheetRef()> function converts an Excel cell reference in 'A1' notation to a zero-indexed C<(row, col)> pair.
my ($row, $col) = sheetRef('A1'); # ( 0, 0 )
my ($row, $col) = sheetRef('C2'); # ( 1, 2 )
This function was contributed by Kevin Mulholland.
=head2 xls2csv($filename, $region, $rotate)
The C<xls2csv()> function converts a section of an Excel file into a CSV text string.
$csv_text = xls2csv($filename, $region, $rotate);
Where:
$region = "sheet-colrow:colrow"
For example '1-A1:B2' means 'A1:B2' for sheet 1.
and
$rotate = 0 or 1 (output is rotated/transposed or not)
This function requires C<Text::CSV_XS> to be installed. It was contributed by Kevin Mulholland along with the C<xls2csv> script in the C<sample> directory of the distro.
