Properly managing and organizing data is a vital aspect of working with Microsoft Excel. One of the most common tasks in Excel is to create formulas that perform calculations and return results based on that data. However, it can be very frustrating when you accidently alter or delete part of the formula. This is where locking cells in Excel comes in handy. In this article, we will explore the different ways to lock cells in Excel to prevent unwanted changes.
Why lock cells in Excel?
As we’ve mentioned, Excel formulas perform calculations that return results based on specific data. When you create a formula in Excel, the formula references certain cells, whether they contain data or other formulas themselves. If any of these referenced cells are accidentally modified or deleted, it can dramatically affect the accuracy of the formula, and potentially the entire workbook. By locking cells, you can protect cell references within formulas from any changes that can be made accidentally or intentionally. By locking cells and ranges, you can also prevent users from editing, deleting, or adding cells or data in an Excel worksheet.
How to lock cells in Excel?
Now that we have established the reasons why it is important to lock cells in Excel, let’s explore some of the methods to do so.
Method 1: Locking cells by protecting the worksheet
The first way to lock cells in Excel is by protecting the worksheet that contains the cells that you want to lock. To do so, follow these steps:
- Select the cells or ranges that you want to lock by clicking on them
- Right-click on the selected cell/s and choose “Format Cells”
- In the “Format Cells” dialog box, click on the “Protection” tab
- Check the box next to “Locked”
- Click “OK”
- Go to the “Review” tab and click on “Protect Sheet”
- Enter your password and confirm it
- Check the permissions you want to grant to the users trying to edit your worksheet
- Click “OK”
Once you have protected your worksheet, the cells you selected in step 1 will be locked. Users who try to modify or delete these cells will be prompted for a password, unless you chose not to allow any editing on the worksheet.
Method 2: Locking cells by using cell references
The second way to lock cells in Excel is through the use of cell references. One of the most common methods is through the use of the $ symbol.
Whenever you create a formula in Excel, the cells referenced in the formula are relative references. Meaning, if you copy and paste the formula to another location in the worksheet, Excel will adjust the references based on the new cell location. However, if you want to lock certain cells in a formula, you have to make sure that Excel does not change the cell reference when the formula is copied.
You can accomplish this by using absolute references by using the $ symbol. For example, let’s say you have a formula that multiplies cell A2 by cell B2, and the result is displayed in cell C2.
If you want to lock cell B2 and prevent it from being accidentally modified, you need to use the absolute reference by adding the $ symbol before both the column letter and row number, like this:
=A2*$B$2
By doing so, the formula will always reference cell B2, regardless of where it is copied or pasted on the worksheet.
Frequently Asked Questions (FAQ)
Here are some common questions and answers regarding locking cells in Excel:
Question 1: Can I lock a cell without protecting the entire worksheet?
Yes, you can lock cells without protecting the entire worksheet by using the “Format Cells” option. Simply select the cell or range that you want to lock, right-click on it, and choose “Format Cells”. In the “Format Cells” dialog box, click on the “Protection” tab, check the box next to “Locked”, and click “OK”. The cell or range you selected will now be locked, but you will still be able to edit other cells on the worksheet.
Question 2: How do I unlock cells in Excel?
To unlock cells in Excel, you need to unprotect the worksheet that contains the cells or ranges you want to modify. To do so:
- Go to the “Review” tab and click on “Unprotect Sheet”
- Enter your password and confirm it
- Select the cells or ranges that you want to unlock
- Right-click on the selected cell/s and choose “Format Cells”
- In the “Format Cells” dialog box, click on the “Protection” tab
- Uncheck the box next to “Locked”
- Click “OK”
The cells or ranges you selected will now be unlocked, and you can modify or delete them as needed.
