How do I protect my Google Sheets spreadsheet from being edited by others?

If you're working with a Google Sheets spreadsheet that contains sensitive data or information you don't want others to edit, it's important to take steps to protect it. Fortunately, Google Sheets makes it easy to limit who can make changes to your spreadsheet. Here are the steps:

1. Open the spreadsheet in Google Sheets and click on the 'Share' button in the top right corner of the screen.
2. At the bottom of the window that appears, click on 'Advanced'.
3. Under the 'Who has access' section, click on the drop-down menu and select 'Restricted'.
4. Enter the email addresses of the people you want to allow to edit the spreadsheet. You can also select whether they can edit or just view the spreadsheet.
5. Click 'Send'.

Once you've set the sharing settings to 'Restricted', only the people you've specifically allowed will be able to edit the spreadsheet. This is a great way to ensure the security and integrity of your data.
