HP Analysis Raw Data: Any known row limit?

Hi,

to analyse our results we use the exported raw data from HP Analysis (especially "AVG Transaction Response Time" raw data) . The raw data are shown like a kind of Excel-Table and they are only exportable as an xls-file.

Does anybody know, if there is an row limit for raw data like in excel, f.e. 65.536 or 1.048.576 rows?

Thanks!
