Excel SUBSTITUTE Function Syntax

SUBSTITUTE(text, old_text, new_text, [instance_num])



The string where you want to do the substitution.


The text you want to substitute.


The text you want to substitute the old_text with.


Optional. The instance of old_text you want to substitute. If omitted, all instances of old_text will be replaced with new_text.


Substitute all instances

Omit the [instance_num] argument to replace all instances of the old_text. In our example, we want to replace “Power” with “Force”. The following formula replaces both instances of the text “Power”.

=SUBSTITUTE(“By the Power of Grayskull… I Have the Power!”,”Power”,”Force”)

Substitute specific instance

If we set [instance_num] to 2, in our example, the SUBSTITUTE function only replaces the 2nd instance of the text “Power”.

=SUBSTITUTE(“By the Power of Grayskull… I Have the Power!”,”Power”,”Force”,2)

Summary and Tips

  • Use the REPLACE function to replace any text in a specific location. For example, to replace a 5 character text starting from the 4th character:
  • The Excel SUBSTITUTE function is case-sensitive.
  • To remove a specific character or text, replace it with an empty string (“”).
    =SUBSTITUTE(text,” “,””)
  • Use the SUBSTITUTE function in a nested form to substitute different characters with a single formula. For example, to remove space and dash characters, use:
    =SUBSTITUTE(SUBSTITUTE(text,” “,””),”-“,””)
