Replace first n char with another
To replace the first n characters with another string, you just need the Replace function.
Select a cell you will place the formula, and type this =REPLACE(A1,1,3,"KTE"), then drag fill handle over the cells you need.
In the formula, A1 is the cell you use, 1 and 3 indicate to replace the first 3 characters, KTE is the new string. If you want to replace 3 characters from the second character, use the formula like this =REPLACE(A1,2,3,"KTE").
