This article will discuss how you can protect formulas in Microsoft Excel. Sometimes, when you share spreadsheets with other people, you might want no one to edit any formulas used in the calculation because manipulation of formulas may result in erroneous results. Again, at times we may need to protect formulas only. For example, you have shared an excel file with your superior and he is allowed to make some changes to the spreadsheet. However, your superior should not change any formula used in the spreadsheet. In such cases, we can protect cells with formulas only.

Step-by-Step Guideline to Protect Formulas in Excel
Suppose we have the below dataset containing sales data. Here I have used formulas to calculate revenues.
Now, I will protect the above cells with formulas by following some easy steps.
Step 1: Unlock All Cells from Excel Worksheet
To protect formulas only, first, we have to unlock all the cells in an excel worksheet. By default, all the cells in excel remain locked. Follow the below steps to unlock all the cells.
- Initially, select all the cells in the worksheet by pressing Ctrl + A.
- Next press Ctrl + 1 to bring the Format Cells dialog. Or you can right-click on the selection to get the dialog.
- When the Format Cells dialog shows up, select the Protection tab.
- Uncheck the Locked box option, and press OK.
Step 2: Find Cells That Contain Formulas
Now we will find which cells contain formulas. To do that follow the below steps:
- First, select the entire worksheet by pressing Ctrl + A.
- Next, from Ribbon, go to Home > Editing group.
- Then from the Editing group, go to Find & Select > Go To Special.
- As result, the Go To Special dialog appears, put a checkmark on Formulas, and press OK.
- Consequently, all the cells that contain formulas are highlighted.
Step 3: Lock Formula Cells Only
This time we will lock formula containing cells and follow the below steps to do the task.
- While keeping the cells with formulas, press Ctrl + 1 to bring the Formula Cells dialog.
- Then put a checkmark on the Locked option under the Protection tab, and press OK. This will lock the formula cells again.

- Now, make sure you have put a checkmark on the ‘Select locked cells’ option. If you want, you can enter a password to unprotect the sheet, but it is optional.
- Press OK after that.
- Finally, all the formulas are now protected. If you double-click any of the cells that have formulas, excel will show the below warning which means you cannot edit any formulas now.
How to Hide Formulas in Excel for Protection
Sometimes, you might want to hide the formulas which you have used in your calculation. It is very simple to hide formulas in excel. Here are the steps to perform the task.
