How to turn a string formula into a “real” formula

Question

I have 0,4*A1 in a cell (as a string). How can convert this \"string formula\" into a real formula and calculate its value, in another cell?

Answer 1

I Concatenated my formula as normal but at the start I had '= instead of =.

Then I copy and paste as text to where I need it. Then I highlight the section saved as text and press ctrl + H to find and replace.
I replace '= with = and all of my functions are active.

Its a few stages but it avoids VBA.

I hope this helps,
