reader for common spreadsheet formats

 Spreadsheet::Read is a Perl module that tries to transparently read arbitrary
 spreadsheet files and return its content in a universal manner independent of
 the parsing module that does the actual spreadsheet scanning.
 .
 For older OpenOffice and/or LibreOffice files, this module uses
 Spreadsheet::ReadSXC (packaged as libspreadsheet-readsxc-perl).
 .
 For Microsoft Excel, this module uses Spreadsheet::ParseXLSX (for newer files;
 see the libspreadsheet-parsexlsx-perl package) or Spreadsheet::ParseExcel
 (available in libspreadsheet-parseexcel-perl)
 .
 For Comma-Separated Value (CSV) files, this module uses Text::CSV (either the
 pure perl version in libtext-csv-perl, or, if available, the XS-accelerated
 version packaged as libtext-csv-xs-perl).
 .
 For SquirrelCalc, there is a very simplistic built-in parser.
