in reply to Spreadsheet::ParseXLSX returning zero

This might not work but what do the cell values look like when the file is parsed using Excel::ValueReader::XLSX?

If you parse a lot of XLSX files and only need the values then Excel::ValueReader::XLSX is substantially faster at parsing files. Recent versions of Spreadsheet::Read are also able to use it as a backend if you want to be able to switch between parsers.

    Well that seems to have worked!

    Thanks!

    I didn't know about that module, and given how much else it installed, it appears to be relatively independent of Spreadsheet::(.*)

    It looks like I have some rewriting to do - I'll come back and post if I can figure out what the source of the problem with the .xlsx file is.
