This tutorial shows how to hide formulas in Excel so they do not show up in the formula bar. Also, you will learn how to quickly lock a selected formula or all formulas in a worksheet to protect them from being deleted or overwritten by other users.
Microsoft Excel does its best to make formulas easy to interpret. When you select a cell containing a formula, the formula displays in the Excel formula bar. If that's not enough, you can evaluate each part of the formula individually by going to the Formulas tab > Formula Auditing group and clicking the Evaluate Formulas button for a step-by-step walkthrough.
But what if you don't want your formulas to be shown in the formula bar, nor anywhere else in the worksheet, for confidentiality, security, or other reasons? Moreover, you may want to protect your Excel formulas to prevent other users from deleting or overwriting them. For example, when sending some reports outside your organization, you may want the recipients to see the final values, but you don't want them to know how those values are calculated, let along making any changes to your formulas.
Luckily, Microsoft Excel makes it fairly simple to hide and lock all or selected formulas in a worksheet, and further on in this tutorial we will show the detailed steps.
If you've put a lot of effort in creating an awesome worksheet that you need to share with other people, you certainly wouldn't want anyone to mess up any smart formulas that you worked so hard on! The most common way of preventing people from tampering with your Excel formulas is to protect the worksheet. However, this does not just lock formulas, but rather locks all cells on the sheet and stops users from editing any of the existing cells and entering any new data. Sometimes you may not want to go that far.
The following steps demonstrate how you can only lock a selected formula(s) or all cells with formulas on a given sheet, and leave other cells unlocked.
For starters, unlock all of the cells on your worksheet. I realize that it may sound confusing because you have not locked any cells yet. However, by default, the Locked option is turned on for all cells on any Excel worksheet, whether an existing or a new one. This does not mean that you cannot edit those cells, because locking cells has no effect until you protect the worksheet.
So, if you want to lock only cells with formulas, be sure to perform this step and unlock all cells on the worksheet first.
If you want to lock all cells on the sheet (whether those cells contain formulas, values or are blank), then skip the first three steps, and go right to Step 4.
Select the cells with the formulas you want to lock.
To select non-adjacent cells or ranges, select the first cell/range, press and hold Ctrl, and select other cells/ranges.
To select all cells with formulas on the sheet, do the following:
Now, go to lock the selected cells with formulas. To do this, press Ctrl + 1 to open the Format Cells dialog again, switch to the Protection tab, and check the Locked checkbox.
The Locked option prevents the user from overwriting, deleting or changing the contents of the cells.
To lock formulas in Excel, checking the Locked option is not sufficient because the Locked attribute has no effect unless the worksheet is protected. To protect the sheet, do the following.
This password is needed for unprotecting the worksheet. No one, even yourself, will be able to edit the sheet without entering the password, so be sure to remember it!
Also, you need to select the actions that are allowed in your worksheet. As you see in the screenshot above, two checkboxes are selected by default: Select locked cells and Select unlocked cells. If you click the OK button leaving only these two options selected, the users, including yourself, will be able only to select cells (both locked and unlocked) in your worksheet.
If you want to allow some other actions, e.g. sort, auto-filter, format cells, delete or insert rows and columns, check the corresponding options in the list.
Done! Your Excel formulas are now locked and protected, though visible in the formula bar. If you also want to hide formulas in your Excel sheet, read through the following section.
Tip. If you need to edit or update your formulas once in a while and you don't want to waste your time on protecting / unprotecting the worksheet, you can move your formulas to a separate worksheet (or even workbook), hide that sheet, and then, in your main sheet, simply refer to the appropriate cells with formulas on that hidden sheet.
Hiding a formula in Excel means preventing the formula from being shown in the formula bar when you click a cell with the formula's result. To hide Excel formulas, perform the following steps.
You can select non-adjacent cells or ranges by holding the Ctrl key, or the entire sheet by pressing the Ctrl + A shortcut.
To select all cells with formulas, use the Go To Special > Formulas feature as demonstrated in Selecting cells with formulas.
The Locked attribute, which prevents the contents of the cells from editing, is selected by default, and in most cases you'd want to leave it this way.
Note. Please remember that locking cells and hiding formulas has no effect until you protect the worksheet (a short notice right underneath the Locked and Hidden options on the Format Cells dialog points to the next steps). To make sure of this, select any cell with a formula, and look at the formula bar, the formula will still be there. To really hide formulas in Excel, be sure to protect the worksheet.
To get the previously hidden formulas to show in the formula bar again, do one of the following:
Note. If you've hidden the formulas before protecting the workbook, you may want to uncheck the Hidden checkbox after unprotecting the worksheet. This won't have any immediate effect because the formulas start showing in the formula bar as soon as you've removed the worksheet protection. However, if you ever want to protect the same sheet in the future, but let the users see the formulas, make sure the Hidden attribute is not selected for those cells (select the cells with formulas, press Ctrl + 1 to open the Format Cells dialog, go to the Protection tab and remove a tick from the Hidden box).
This is how you can hide and lock formulas in Excel. In the next tutorial, we will discuss various ways to copy formulas and you will learn how to apply a formula to all cells in a given column in a click. I thank you for reading and hope to see you again soon!
