  • num_chars - The number of characters to replace.

Usage notes 

The REPLACE function replaces characters in a text string by position. The REPLACE function is useful when the location of the text to be replaced is known or can be easily determined.

REPLACE function takes four separate arguments. The first argument, old_text, is the text string to be processed. The second argument, start_num is the numeric position of the text to replace. The third argument, num_chars, is the number of characters that should be replaced. The last argument, new_text, is the text to use for the replacement.


To replace the "C" in the path below with a "D":

=REPLACE("C:\docs",1,1,"D") // returns "D:\docs"

To replace 3 characters starting at the 4th character:

=REPLACE("XYZ123",4,3,"456") // returns "XYZ456"

You can use REPLACE to remove text by specifying an empty string ("") for new_text. The formula below uses REPLACE to remove the first character from the string "XYZ":

=REPLACE("XYZ",1,1,"") // returns "YZ"

The example below removes the first 4 characters:

=REPLACE("www.google.com",1,4,"") // returns "google.com"
