Make an Excel Workbook Read-Only but Usable in Excel for the Web
Product
Excel for the Web
Device & OS
not provided
Scenario
Sharing a master calculator workbook online for multiple users to interact with simultaneously while protecting the core formulas.
Observed behavior
When desktop read-only or modification-password settings are applied to the workbook, Excel for the Web completely blocks all data entry and editing.
Before you start

Keep in mind that Excel for the Web has inherent design limitations regarding workbook protection. You will need access to the desktop version of Excel to utilize advanced read-only and cell protection features.

Solution 1Recommended

Open the Workbook in Desktop Excel

Bypass the web platform's limitations by forcing the file to open in the full desktop version of Excel, which supports advanced read-only data entry.

Excel for the Web does not fully support password-to-modify or read-only settings while simultaneously allowing partial cell edits. To use the shared workbook as intended, users must open the file in the desktop application.

1
Open the file online

Navigate to the shared Excel workbook link in your web browser and log in if prompted.

2
Switch to the Desktop App

On the top ribbon of Excel for the Web, click on the 'Viewing' or 'Editing' dropdown button, then select 'Open in Desktop App'.

3
Enter data in unlocked cells

Once the file opens in the desktop version, users can enter values into the calculator's unlocked cells while the master file remains read-only.

Open the Workbook in Desktop Excel
Desktop Requirement: All users attempting to use the master calculator must have the desktop version of Excel installed on their computers for this workaround to function properly.

Frequently Asked Questions

Why does Excel for the Web lock my entire read-only workbook?

This is a design limitation. Excel for the Web does not currently support partial editing in files saved with a 'password to modify' or strict read-only recommendation. It defaults to locking the entire document to maintain file integrity.

Can I use an Excel template (.xltx) in Excel for the Web?

When you upload an .xltx file to OneDrive or SharePoint and open it in the browser, Excel for the Web often opens it for editing directly rather than creating a new unsaved copy. Templates function best when opened in the desktop app.

Is there a web-based alternative for a shared calculator?

If you need a purely web-based solution for users to input data without changing a master sheet, consider using Microsoft Forms to collect the input. However, providing real-time calculation feedback requires advanced tools like Power Apps.
