reader for common spreadsheet formats

 Spreadsheet::Read is a Perl module that tries to transparently read any
 spreadsheet and return its content in a universal manner independent of the
 parsing module that does the actual spreadsheet scanning.
 .
 For OpenOffice and/or LibreOffice files, this module uses
 Spreadsheet::ReadSXC (libspreadsheet-readsxc-perl).
 .
 For Microsoft Excel, this module uses Spreadsheet::ParseExcel
 (libspreadsheet-parseexcel-perl), or Spreadsheet::ParseXLSX
 libspreadsheet-parsexlsx-perl).
 .
 For Comma-Separated Value (CSV) files, this module uses Text::CSV_XS
 (libtext-csv-xs-perl) or Text::CSV_PP (libtext-csv-perl).
 .
 For SquirrelCalc, there is a very simplistic built-in parser.
