Google Sheets is an excellent tool for collaboration, but sometimes you need to lock cells to ensure that sensitive information remains secure. You can lock cells in Google Sheets using the Protect Sheets feature.
This feature allows you to select specific cells or ranges to lock, and it's easy to set up. Simply go to Tools > Protect sheets and ranges, and then select the cells you want to lock.
By locking cells, you can prevent others from editing or deleting sensitive data, which is especially important if you're working with confidential information. This is a must-have feature for anyone who needs to collaborate on spreadsheets.

Locking cells that contain formulas can be done by using a specific formula syntax, but it's not always the most intuitive method.
For example, in Google Sheets, you can use the "LOCKED" formula syntax to prevent edits, but it's not as straightforward as other methods.
