Hi,

I write here so people can find the problem when they search.

XLSX is a Zipped file format with XML. When some applications (it seems Libre Office and others) save as XLSX, they set the dimension size bad. And all the Perl modules I could find failed on that.

A typical example is that in a sheet file (like xl/worksheets/sheet1.xml, after unpacking) you find 

<dimension ref="G2296"/>
The Spreadsheet::ParseXLSX module (and others) seems to expect something like "A1:G2296" there. It sets the values for Min/Max Column/Row wrong.

Spreadsheet::ParseXLSX use Spreadsheet::ParseExcel objects for worksheets etc, so the API is compatible. The get_cell() method there just returns undef if the asked cell is outside the dimension boundaries (which it of course is).

A temporary fix would be to set the MinRow/MinCol/MaxCol/MaxRow values in the spreadsheet object:

for my $s ($parsed_document->worksheets() ) { 
  $s->{MinRow}=0;
  $s->{MinCol}=0;
  # $s->{MaxCol}=100;   (Edit: Not needed)
  # $s->{MaxRow}=7000;  (Edit: Not needed)
  ...
  my $c = $s->get_cell($row, $column);
  ...

I don't really know enough about the XLSX format. I assume the easy solution is a few lines. Like keeping up max/min column numbers when reading the file. I'll send in a bugfix when I get so far. (With tests so I don't get any grumbles back this time. :-) )
