By using =Len() you’re going to return the character count including spaces by default.
This formula will return 9, this is because there’s a space between “hey” and “there”.
Here’s the formula to get character count without spaces:
=len(SUBSTITUTE("hey there"," ",""))
This will return: 8
How does this work?
By nesting the Substitute formula, we can “substitute” (remove) the whitespaces and then the len() formula will count the characters. If you were to use the substitute formula on its own here, it would return “heythere”, which is why the len() formula wrapper will return 8.
There you go. This will work in both Excel and Google docs spreadsheets 🙂
