I am trying to compare some old spreadsheets and upgrade to the new and have
a case in try to determine if a value was added to a formula inside a cell.
So I would like to do a search/find on the contents of the FORMULA in the
cell.

Example: Cell A1 Contains a formula +F12+F34+F67

Is there a function that can search the formula? Example: FIND "F34" in
cell A1. Everything I can see so far you can only search the results, not
the formula.

Thank you in advance for your help!!!
