Objective: Change cells that have rounded formulas into cells with the same formulas but not rounded.

Situation: Excel 2010 workbook w/ about 40 worksheets; hundreds of cells with different formulas that are rounded, i.e. say, =Round(A1*G5,2) I replaced all the Round( characters with a blank, which got rid of the Round( but turned the cells into text with the formatting mark ' in front of the = sign because the cells now ended in ,2) which of course is not a legal formula. I then replaced ,2) which got the cells to what I want, i.e. the formulas without rounding but the cells are still text, i.e. they still have a ' formatting mark in front of the = sign and I don't know how to get the format mark out so that I'm left with non-text formulas, i.e. say, =A1*G5

Everything I've tried leaves cells as text with the formatting mark ahead of the = sign. Any ideas?
