You can replace a formula with its calculated value so that the formula no longer recalculates. Replacing a formula with its result can be helpful if the workbook contains many formulas or complex formulas. Using the static data of the result can improve performance. If you want to replace only part of a formula, you can replace only the part that you don't want to recalculate. You can convert formulas to their values on a cellbycell basis or convert a whole range immediately.
Do any of the following:
