Substitutes new_text for old_text in a text string. Use SUBSTITUTE when you want to replace specific text in a text string; use REPLACE when you want to replace any text that occurs in a specific location in a text string.

Syntax

SUBSTITUTE(text,old_text,new_text,instance_num)

Text   is the text or the reference to a cell containing text for which you want to substitute characters.

Old_text   is the text you want to replace.

New_text   is the text you want to replace old_text with.

Instance_num   specifies which occurrence of old_text you want to replace with new_text. If you specify instance_num, only that instance of old_text is replaced. Otherwise, every occurrence of old_text in text is changed to new_text.

Example

The example may be easier to understand if you copy it to a blank worksheet.
