How do I...
Put a password on a workbook
What to do
- Go to File, then Info.
- Click Protect Workbook, then Encrypt with Password.
- Type the password twice.
Good to know
- If you lose the password, Microsoft cannot get the file back. Store it somewhere safe.
The idea in general
Nobody can open the file without the password.
What I assumed
- You are using Excel on a computer. Menus can look a little different on a Mac or in a browser.
