- In the `Protection` tab, select `Locked` and click `OK`.
- Finally, click `OK` to apply the conditional formatting rule.
Locking Cells Based on Specific Conditions
Sometimes you’ll need to lock cells based on specific conditions, such as dates, numbers, or text. In this case, you can use a combination of VBA macros and conditional formatting to achieve your goals.
- Create a new module in the Visual Basic Editor and declare a variable to store the range you want to lock, for example: `Dim lockRange As Range`.
- Set the range using the `Set` , for example: `Set lockRange = Range(“A1”)`.
- Use the `If` statement to check if the cell meets the condition, for example: `If Range(“A1”).Value > 10 Then`.
- If the condition is met, use the `Lock` method to lock the range, for example: `lockRange.Lock Method:=xlLockFormat`.
- Finally, run the macro by clicking `Run` > `Run Sub/user form` in the Visual Basic Editor or by pressing `F5`.
Locking Cells Using Range-Based Formatting
In some cases, you may need to lock cells based on a range-based format, such as a range of dates or numbers. In this case, you can use the `Range` object to lock the cells.
- Select the range you want to lock and go to the `Home` tab in the Excel ribbon.
- Click on `Format Cells` > `Protection` in the ribbon.
- In the `Protection` tab, select `Locked` and click `OK`.
- Finally, click `OK` to apply the range-based formatting rule.
