You may find yourself working with large data sets in Excel and it can be very frustrating if you accidentally edit a formula that is integral to your work. It is important to lock cells and formulas to prevent them from being accidentally altered. Here, we will discuss some methods to lock cells and formulas in Excel so that you can save yourself time and aggravation.
To start off, locking cells is not a difficult task. Before we begin, let me explain what we mean by “locking” cells. When you lock cells in Excel, they are protected from being altered by anyone but yourself. This means that someone else, or even you yourself, will not be able to edit or delete the data in the locked cells without first unlocking them. So, let’s get started with locking cells.
1. Locking Cells
Open your Excel spreadsheet and select the cells that you want to lock. To select multiple cells, click the first cell and drag your mouse to highlight the rest of the cells. Once you have selected the cells, right-click and select “Format Cells” from the menu. A dialog box will appear.
Click on the “Protection” tab at the top of the dialog box. You will see a checkbox next to “Locked”. Make sure this box is checked. Click “OK”.
Now to protect the sheet, go to the “Review” tab at the top of the Excel window. Click on “Protect Sheet”. You will be asked to create a password. Make sure to create a password that you will remember. After typing in the password, click “OK”.
Now your cells are locked and your sheet is protected.
2. Locking Formulas
Locking formulas can be done in the same way as locking cells. The only difference is that you need to add a dollar sign ($) before the cell reference in the formula.
For example, =A1+B1 is a formula that adds the values in cell A1 and cell B1. If you want to lock the formula so that the cells cannot be accidentally edited, you need to add dollar signs.
The new formula will look like this: =$A$1+$B$1.
By adding the dollar sign, Excel will treat the cell references as absolute instead of relative. This means that even if you copy the formula to another cell, the cell references will remain the same.
Once you have locked the formulas, you can now protect the sheet as explained in the previous step.
3. FAQ
Q: Can I unlock the cells and formulas that I have previously locked?
A: Yes, to unlock the cells, you can simply go back to the “Review” tab and click on “Unprotect Sheet”. You will be prompted to enter the password that was previously set. Once entered, the sheet will be unprotected and you can edit the cells and formulas.
Q: Can I lock specific cells while leaving others editable?
A: Yes, you can. The process is the same as locking cells, but instead of selecting all of the cells, you need to select just the cells that you want to lock. Once the cells are selected, right-click and select “Format Cells” from the menu. A dialog box will appear. Click on the “Protection” tab at the top of the dialog box. You will see a checkbox next to “Locked”. Make sure this box is checked only for the cells you want to lock. Click “OK”. Now the selected cells are locked while the other cells remain editable.
