Question

When evaluating the value of a cell in a worksheet in Excel, is the following statement true?

If and only if Len(cell.Value) = 0, then cell.Value = "".

This would imply that it is safe to check that there are zero characters in a cell instead of comparing the cell value to an empty string.

Answer 1

Yes, they do the same thing.

However, I would advise that you use the IsEmpty function to check for empty cells. If you enter a single quote into a cell ' both the len check and the ="" check will both state the the cell is empty. When in actual fact it isn’t.

IsEmpty will return false in this scenario.

And it’s also a little easier to read.
