Text
SUBSTITUTE
Replaces text by its content.
Syntax
SUBSTITUTE(text, old_text, new_text, [instance_num])Example: =SUBSTITUTE(A2,"-","")
Available in: All versions
SUBSTITUTE replaces specific text inside a string: =SUBSTITUTE(text, old_text, new_text, [instance_num]). It is the tool for removing dashes from phone numbers, swapping characters or replacing only the nth occurrence.
When to use it
- You remove or replace a known character or word across many cells.
- You want to change only the second or third occurrence of a character.
- You count how often a character appears in a cell.
- You prepare data for matching, such as removing hyphens.
Arguments explained
- text. The string in which you want to replace pieces, usually a cell reference.
- old_text. The exact text to find. Matching is case sensitive and wildcards are not supported.
- new_text. The replacement. Use "" to delete old_text.
- instance_num. Optional. Replace only the nth occurrence of old_text. If omitted, every occurrence is replaced.
Worked examples
Replace one occurrence only
| A | |
|---|---|
| 1 | List |
| 2 | a,b,c,d |
Formula: C1: =SUBSTITUTE(A2,",",";",2)
Result: a,b;c,d
The fourth argument 2 limits the change to the second comma.
Count a character
| A | |
|---|---|
| 1 | Tags |
| 2 | red,green,blue |
Formula: C1: =LEN(A2)-LEN(SUBSTITUTE(A2,",",""))
Result: 2
Removing every comma shortens the text by the number of commas.

Common errors and how to fix them
- Case mismatch. SUBSTITUTE is case sensitive. "Pen" does not replace "pen".
- Result is text. Cleaned numbers such as "5551234567" are text. Multiply by 1 if you need a number.
- Nothing changes. The old text has to match exactly, including hidden spaces. Check with LEN or FIND.
- Confusion with REPLACE. REPLACE changes characters by position; SUBSTITUTE changes them by content.
- Wildcards do not work. Characters such as * and ? are treated as plain text in old_text. For pattern-based cleanup, use Find and Replace or a combination of FIND, LEFT and RIGHT.
- Replacing several different items. Nest the calls, for example SUBSTITUTE(SUBSTITUTE(A2,"-","")," ",""), working from the inside out, so each step cleans the result of the previous one.
