Import Error Says "Can't Load More Than 1000 Rows"

Import Error Says "Can't Load More Than 1000 Rows"

I'm trying to import a Google Sheets file into CRM using a FREE account.  I saved it both as a xlsx, and csv file.  I only have maybe 750 rows, yet everytime I try to import either file type it gives me an error msg saying it can't import more than 1000 rows.  What's up with that?
