1000? No. There's two. Openxml and the original xls. OpenXML can be scanned for issues like any other XML file. Alas, it's more difficult to get excel to accept that it shouldn't delete leading zeros than it is to check a spreadsheet's sus-o-scale. |

xls morphed with every version of Microsoft Excel. MS Excel has pretty good backwards compatibility, but making an xls parser is notoriously hard because of the many differences between versions.
