Currently Jedox Spreadsheet supports Workbooks with Sheet dimensions compatible with Excel 2003 - 256 columns (A-IV), 65535 rows. Newer Excel Version (2007+) support 16384 colums and 1048576 rows. Such workbooks can be loaded into Jedox Web but their size would be truncated to 256 x 65535.

Thanks for the idea This feature has been evaluated by us and we will not implement at this time. Usability of such huge data tapestries is questionable in most usage contexts. Mass data sits in the DB (or even source system) reports should only show a fraction.
