How to Lock an Excel Sheet in Excel Online
The process of locking a sheet in Excel Online might seem daunting at first, but it’s quite straightforward once you know the steps. Here’s how to do it:
Step 1: Sign In to Excel Online
Before you can lock a sheet, make sure you’re signed into your Microsoft account and open the Excel Online application. Navigate to the spreadsheet you want to protect.
Step 2: Select the Cells to Lock
If you need to lock specific cells, select them:
- Click the cell or use the mouse to drag over multiple cells.
- Right-click and choose Format cells from the context menu.
- Go to the Protection tab.
- Ensure the Locked option is checked. By default, all cells are locked, but they will not be until the sheet is protected.
Step 3: Protect the Sheet
To actually lock the cells:
- Go to the Review tab on the ribbon.
