It can be very useful to password protect cells in Excel so that other people cannot accidentally (or even deliberately) overwrite valuable data of formulas and functions. However, there are times when you need Excel cell protection password but you allow other users to access and edit other cells on the same spreadsheet. At first glance, this would seem like an unlikely thing to be able to do, but it is in fact very easy to achieve. You'll learn how to password protect cells in Excel and more in this article.

Part 1. How to Password Protect Cells in Excel 2016

You've worked hard on your spreadsheet and now you want to make sure anyone you share it with doesn't inadvertently change cells that shouldn't be changed. Thankfully, Microsoft Excel 2016 and earlier versions let you lock cells to protect them from being modified. You can lock all the cells in a worksheet or specific cells, allowing some parts of the spreadsheet to be changed. Here's how.

Option 1. How to Password Protect All the Cells in a Worksheet

By default, when you protect a sheet or workbook, all of the cells will be locked. This means they can't be reformatted or deleted, and the content in them can't be edited. By default, the locked cells can be selected, but you can change that in the protection options.

1. Navigate to the Review tab.

Navigate to the Review tab

Option 2. How to Password Protect Specific Cells in A Worksheet

There might be times when you want to lock certain cells from being changed but still allow users to adjust other cells in a worksheet. In our example, in an inventory list you might allow unit prices and stock quantities to be updated, but not the item IDs, names, or descriptions. As mentioned above, all cells are locked by default when you protect the sheet. However, you can specify whether a cell should be locked or unlocked in the cell's format properties.

1. Select all the cells you don't want to be locked. These will be the cells that can be edited even after the sheet is protected.

2. Right-click on your selection, select Format Cells and click on the Protection tab. (Alternatively, under the Home tab, click on the expansion icon next to Alignment, and in the Format Cells window go to the Protection tab.)

3. Uncheck "Locked" (which is checked by default) and click OK.

4. Go to Review > Protect Sheet and hit OK to protect the sheet. Any cells you didn't unlock under the Format Cells option (step 3 above) will be locked, while the unlocked cells will be editable:

Note that cell locking (or unlocking) won't take effect until you do step 4, protecting the sheet.

If you want to quickly lock or unlock cells that aren't next to each other, you can use a keyboard shortcut. After selecting a cell or group of cells, use the Format Cells dialog as above to lock or unlock it. Then select your next cell(s) and hit F4 to repeat your last action.

When it comes time to send your Excel spreadsheet, it's important to protect the data that you're sharing. You might want to share your data, but that doesn't mean it should be changed by someone else.

Spreadsheets often contain essential data that shouldn't be modified or removed by the recipient. Luckily, Excel has built-in features to protect your spreadsheets.
