Bushra ParveenBushra Parveen Oct 21, 2026 868 views

Question details

The user wants to permanently enable potentially unsafe external content, such as macros, ActiveX controls, and automatic updates for connected workbooks in Excel for the web.

Product
Excel for the Web
Device & OS
not provided
Scenario
Managing a master workbook connected to multiple secondary files using formulas like FILTER, and needing the linked files to update immediately and automatically when the master file changes.
Observed behavior
Excel for the web blocks permanent enablement of macros and ActiveX controls due to security restrictions, and lacks a built-in feature to immediately auto-update connected workbooks, requiring users to manually refresh links.
Before you start

Ensure you have editing permissions for both your master and secondary workbooks. Keep in mind that Excel for the web operates under strict browser security protocols, which intentionally disables features like ActiveX and automated background linking.

Solution 1Recommended

Manually Refresh Workbook Links

Since automatic updates are restricted in the web version, you must use the Data tab to manually pull the latest data from connected workbooks.

Excel for the web restricts certain automated external data connections to prioritize user security within browser environments. Because of this, continuous automatic updates for connected workbooks require manual intervention.

1
Open the secondary workbook

Open the connected Excel workbook in your web browser where the updated data needs to appear.

2
Navigate to the Data tab

Click on the 'Data' tab located in the top ribbon menu of Excel for the web.

3
Refresh workbook links

Select 'Workbook Links' and click 'Refresh All'. You may need to click this multiple times if the web cache prevents the data from syncing immediately.

Frequently Asked Questions

Why does Excel for the web block macros and ActiveX controls?

Excel for the web operates within web browsers, which use strict security sandboxes. To protect users from malicious scripts, features like macros and ActiveX controls are permanently disabled online.

Can I set connected web workbooks to update automatically?

No, Excel for the web currently lacks a built-in feature to immediately auto-update secondary workbooks when a master file changes online. You must manually use the 'Refresh All' option under the Data tab.

Does owning both files bypass the external content security prompt?

No, file ownership does not override browser security protocols. Excel for the web will still require manual refreshing for linked workbooks, even if you are the owner and creator of all connected files.

How can I permanently enable macros in my Excel file?

You cannot permanently enable macros in Excel for the web. To use and enable macros, you must open your file in a full desktop application like Microsoft Excel for Desktop or WPS Office.
