# Example of formatting using the Spreadsheet::WriteExcel module
#
# This example shows how to use a conditional numerical format
# with colours to indicate if a share price has gone up or down.

use strict;
use Spreadsheet::WriteExcel;
# Create a new workbook and add a worksheet
my $workbook = Spreadsheet::WriteExcel->new("stocks.xls");
my $worksheet = $workbook->add_worksheet();
# Set the column width for columns 1, 2, 3 and 4
$worksheet->set_column(0, 3, 15);
# Create a format for the column headings
my $header = $workbook->add_format();
$header->set_bold();
$header->set_size(12);
$header->set_color('blue');
# Create a format for the stock price
my $f_price = $workbook->add_format();
$f_price->set_align('left');
$f_price->set_num_format('$0.00');
# Create a format for the stock volume
my $f_volume = $workbook->add_format();
$f_volume->set_align('left');
$f_volume->set_num_format('#,##0');
# Create a format for the price change. This is an example of a conditional
# format. The number is formatted as a percentage. If it is positive it is
# formatted in green, if it is negative it is formatted in red and if it is
# zero it is formatted as the default font colour (in this case black).
# Note: the [Green] format produces an unappealing lime green. Try
# [Color 10] instead for a dark green.
#
my $f_change = $workbook->add_format();
$f_change->set_align('left');
$f_change->set_num_format('[Green]0.0%;[Red]-0.0%;0.0%');
# Write out the data

$worksheet->write(0, 2, 'Volume', $header);
$worksheet->write(0, 3, 'Change', $header);
$worksheet->write(1, 0, 'Damage Inc.' );
$worksheet->write(1, 1, 30.25, $f_price); # $30.25
$worksheet->write(1, 2, 1234567, $f_volume); # 1,234,567
$worksheet->write(1, 3, 0.085, $f_change); # 8.5% in green

$worksheet->write(2, 2, 7564, $f_volume); # 7,564
$worksheet->write(2, 3, -0.015, $f_change); # -1.5% in red
$worksheet->write(3, 0, 'Rev Ltd.' );
$worksheet->write(3, 1, 0.13, $f_price); # $0.13
$worksheet->write(3, 2, 321, $f_volume); # 321
$worksheet->write(3, 3, 0, $f_change); # 0 in the font color (black)
