How to Make an Excel Workbook Read-Only but Usable in Excel for the Web
Question details
The user wants to share an Excel workbook online as a master calculator, allowing others to enter values and use formulas without modifying the original document.

- 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.
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.
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.
Navigate to the shared Excel workbook link in your web browser and log in if prompted.
On the top ribbon of Excel for the Web, click on the 'Viewing' or 'Editing' dropdown button, then select 'Open in Desktop App'.
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.

Distribute Individual Copies or Use a Protected Template
Instead of using a single read-only web link, distribute separate files to ensure the master calculator remains untouched.
Manage Protected Spreadsheets Easily with WPS Office
If you frequently encounter limitations with Excel for the Web's protection features, consider switching to WPS Office. It provides robust, free desktop spreadsheet tools that fully support Microsoft Excel formats and advanced cell protection without the online restrictions.
- 1. Download the software: Visit the official WPS Office website to download the free suite for your operating system.
- 2. Open your workbook: Launch WPS Spreadsheets and open your master calculator file directly.
- 3. Apply sheet protection: Navigate to the Review tab to utilize comprehensive cell locking and sheet protection features perfectly compatible with Excel.

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.
