How do I remove the first character of a string?

To delete the first character from a string, you can use either the REPLACE function or a combination of RIGHT and LEN functions. Here, we simply take 1 character from the first position and replace it with an empty string ("").

The formula =RIGHT(A2,LEN(A2)-4) in cell B2 is used to remove the first four characters in the product code.

sub (not gsub) does that:

"fooo#oooooo#bar".sub('#', '') #=> "fooooooooo#bar"
