The used range is continually updated as changes are made to a worksheet, and includes any cell that has ever been used. For example, if A1 contains a value, and that value is deleted, cell A1 is still considered used. Sometimes, a worksheet will have a used range that is much larger than expected. This can cause performance problems and other unexpected behavior. One way to “reset” a used range is to delete all unused columns and rows. Author
