Question details
Determine if Office for the web and WOPI hosts support editing restricted or password-protected sections of Word and Excel documents.

- Product
- Office Online
- Device & OS
- not provided
- Scenario
- A user is trying to edit specific, restricted sections of a Word or Excel document directly within a web browser.
- Observed behavior
- Word documents with modification passwords open in read-only mode, and protected Excel workbooks require opening the desktop application to edit.
Verify if your document already has restricted editing permissions or modification passwords applied before trying to edit it in your browser.
Open and Edit Protected Documents in the Desktop App
Since Office for the web has functional limitations with restricted editing, you must use the desktop versions of Word or Excel to modify protected sections.
Word and Excel for the web do not fully support editing password-protected or restricted documents. Word files with modification passwords will default to read-only mode in the browser, while protected Excel workbooks prompt you to use the desktop client to make any changes.
Log into your Office online account and open the restricted Word or Excel file in your browser.
Locate and click the 'Open in Desktop App' button on the top ribbon menu to transfer the session to your local software.
When the desktop application launches, enter the required modification password to unlock the specific document sections and begin editing.

Manage Restricted Documents Seamlessly with WPS Office
Bypass web browser limitations by using WPS Office, a powerful and lightweight desktop suite that natively supports document protection, restricted editing, and modification passwords without requiring expensive subscriptions.
- 1. Download and Install: Get WPS Office for free from the official website and install it on your PC or Mac.
- 2. Open Your Protected File: Launch WPS Writer or WPS Spreadsheet and open your restricted Word or Excel document.
- 3. Enter Password and Edit: Input the modification password when prompted to easily edit the restricted sections.

Frequently Asked Questions
Why does my Word document open as read-only in Office Online?
If your Word document has a modification password or restricted editing permissions applied, Office for the web cannot process these for editing. It automatically opens the file in read-only mode to prevent unauthorized changes.
Can I password protect a document directly in Word for the web?
No, Office Online does not currently support adding password protection or restricting editing to specific sections. You need to use the desktop version of Word or Excel to apply these security settings.
Is there a way to bypass the 'Open in Desktop App' prompt for protected Excel files online?
No, if an Excel workbook or worksheet is protected, Office for the web explicitly requires the desktop application to edit it safely. You must launch the desktop version to modify the protected cells.
