No, buddy...that's 65,535 (less the column names, of course) per workbook. 256 columns, 65,536 rows. Of course, try packing that much in and you'll likely come up way shorter. i.e. Once Excel's cell memory or heap space get(s) taxed, you're going to get out of memory errors. Of course, you can tweak this (and you can double-up rows within the same sheet, if your column demands allow, but...why push the upper bounds? Use Access if you've got more data than Excel can handle...or something even more robust, if need be.
