## Remove prefix or suffix from string

This tutorial explains two formulas to remove a specific number of prefix or suffix from string in a cell in Excel.

#### Remove prefix from string with a combination of the RIGHT and LEN functions

As the below screenshot shown, the prefix you want to remove is always 4 characters long, please do as follows to remove it.

Generic formula

=RIGHT(A1,LEN(A1)-4)

Arguments

A1: Represents the cell containing the string in which you want to remove the prefix.

How to use this formula?

1. Select a blank cell to output the result. In this case, I select D3.

2. Enter the below formula into it and press the Enter key. Select the result cell and then drag its Fill Handle down to apply the formula to other cells.

=RIGHT(B3,LEN(B3)-4)

Note: The number 4 in this formula indicates the leftmost four characters in the string you want to remove. You can change it as you need.v

How this formula works?

=RIGHT(B3,LEN(B3)-4)

1. LEN(B3): The LEN function calculate the total length of text string "001-OT2020-BT", and returns the result as 13;

2. RIGHT(B3,13-4): And then the RIGHT function extracts 9 characters (13-4=9) from the text string "001-OT2020-BT" and returns "OT2020-BT".
Note: As the total length of text string "001-OT2020-BT" is 13, and the prefix you want to remove contains 4 characters, here we need to subtract 4 from 13 to keep only 9 characters of the string.

#### Remove suffix from string in a cell with a combination of the LEFT and LEN functions

In this case, assuming the suffix you want to remove contains 3 characters as the below screenshot shown. You can use a combination of the LEFT and LEN functions to get it down.

Generic formula

=LEFT(A1,LEN(A1)-3)

Arguments

A1: Represents the cell containing the string in which you want to remove the suffix.

How to use this formula?

1. Select a blank cell to output the result.

2. Enter the below formula into it and press the Enter key. Select the result cell and then drag its Fill Handle down to apply the formula to other cells.

=LEFT(B3,LEN(B3)-3)

Note: In this formula, the number 4 indicates the rightmost 3 characters in the string you want to remove. You can change it as you need.

How this formula works?

=LEFT(B3,LEN(B3)-3)

1. LEN(B3): The LEN function calculate the total length of text string "001-OT2020-BT", and returns the result as 13;

2. LEFT(B3,13-3): And then the RIGHT function extracts 10 characters (13-3=10) from the text string "001-OT2020-BT" and returns "001-OT2020".
Note: As the total length of text string "001-OT2020-BT" is 13, and the suffix you want to remove contains 3 characters, here we need to subtract 3 from 13 to keep only 10 characters of the string.
