Help prevent changes to a final version of a file

Office 365 订阅, Office Online, Office 2019, Office 2016, Office 2013, Office 2010

Use Mark as Final to make your Word, Excel, or PowerPoint file read-only. When you mark as final, typing, editing commands, proofing marks are disabled or turned off, and the file becomes read-only, and the Status property of the document is set to Final.

Notes: 

  • The Mark as Final command is not a security feature. Anyone who receives an electronic copy of a file that has been marked as final can edit that file by removing the Mark as Final status from the file.

  • If you want to encrypt a presentation with a password or restrict who can edit it, see Add or remove protection in your document, workbook, or presentation.
