Simple script for Google Sheet, search and replace text

I use macro in Google sheet to modify my sheet but I would lite to use the search and replace function as well which the standard macro won´t record - I need a script.

I found a script: https://support.google.com/docs/thread/98655402/find-and-replace-in-a-macro?hl=en

I just need fast help to implement it in my sheet and for my words:

I would like to replace or remove these words:
Standard -> SHIRT
Onesize -> STORLEK
+25kr -> (Nothing just remove)

Once accepted I will share a google sheet with you to implement the script.
