What is the maximum allowed rows in a Microsoft Excel .xls or .xlsx

Question

Is there a limit? I couldn't find one posted.

Answer 1

Have a look at this link. A quick summary:

Excel 2007-2010 -> 1,048,576 rows
Excel '97-2003  ->    65,536 rows
Excel pre-'97   ->    16,384 rows

Answer 2

Really, you searched? Where, do tell.

Because the first or second answer on Google upon "maximum number of rows in Excel" gives a link (several, actually) with

Starting in Excel 2007, the "Big Grid" increases the maximum number of rows per worksheet from 65,536 to over 1 million, and the number of columns from 256 (IV) to 16,384 (XFD).
