I just started using Excel::Writer::XLSX and it's nt too difficult, I think, but here is something I don't understand.

The below example code puts the text "4004885000007" into A1 of an excel sheet and sets the format to "@", the Text format.

Now what happens when I open the file:

1. The text is not displayed as 4004885000007 but just as 4E+12.
2. When I check the cell format it is correctly set to "Text"
3. When I press Enter in the input bar(?) where the full text 4004885000007 is displayed, the 4E+12 in the cell is replaced with the full number
4. Additionally a warning is displayed that I stored a number as text - Great! That's what I wanted in the first place...

Does anyone here has an idea how I could get the text to be displayed correctly?

use strict;
use warnings;
use Excel::Writer::XLSX;

# Create a new workbook called simple.xls and add a worksheet
my $workbook  = Excel::Writer::XLSX->new( 'a_simple.xlsx' );
my $worksheet = $workbook->add_worksheet();

my $textformat = $workbook->add_format();
$textformat->set_num_format( 0x31 );
$worksheet->write( 0, 0, "4004885000007", $textformat );

$workbook->close();
