Google spreadsheet tricks#

Remove characters from a string in a cell with Google spreadsheet#

Goal#

Remove the first 2 characters from a string in cell D1 :

 =RIGHT(D1,LEN(D1)-2)

Explanations#

LEN(D1) returns the length of the string in a cell.
RIGHT(D1, X) returns a substring from the end. First argument is the string. Seconde argument is the length of the substring to return.

Alternatively, to remove the last 2 characters, use :

 =LEFT(D1,LEN(D1)-2)
