Locking or protecting cells with formulas is crucial for calculations. This will stop other people from deliberately or mistakenly editing or deleting your formula in Excel.
Almost each of us has used formulas and functions in excel. Without function, excel is meaningless. The best power excel has is complex calculation. But without formula it is impossible. But if you misspelled a formula, remove a character from a formula or mistakenly change the formula, you won’t be able to get the proper calculation. Now if you are using a workbook by yourself and you know every cell where you have formula, you still have chances to mistakenly edit your formula cell. If you are working with a colleague or someone else on a single workbook, or you sent your workbook for review. The chance of removing or editing your formula is greater. In this situation, the best solution is to protect formulas. But you can’t just lock the entire worksheet or the workbook. You’ll need to enter data and you don’t want to enter the password every time you enter something on your worksheet.
All you need is a sophisticated technique that will only protect cells with formulas in excel. All the cells that don’t have any formula or function in it will be open for all. Also, for the checking purpose, you need to be able to see the formula itself. In this tutorial I’ll show you an excellent way on how to lock formulas in excel. Following steps will do the job.

Sometimes we need to hide sensitive formulas so that no one can see them. You can hide formulas with and without a password, and it only takes a minute.......
