Does anyone know of a limit on Perl hashes

The very first reply in this entire thread is correct. There is no limit other than the space your system might have to store it.

when read from Excel spreadsheets? It seems to die around 670

Save your spreadsheet as CSV and read from that instead. Might save a lot of trouble and would also help you prepare the SSCCE that would be required to dig further.
