Excel 2010 saved as .xlsx will only allow 65536 rows

Hello Hello...

Is there a reason for this or perhaps I'm missing something in the settings?

You're in compatibility mode. Save, close, and reopen.

Thanks Shg!

It didn't make sense that I was in compatibility mode since the version of excel on this computer is 2010...

However, I was working with a few open Excel books which were 2003 - and I'm guessing that is what threw this book into compatibility mode

Thanks Again!
