Fix Power Automate Not Refreshing Excel Data via TypeScript

Maira MehtabMaira Mehtab Sep 22, 2026 869 views

Question details

The user's TypeScript script successfully refreshes an Excel data connection locally but fails to execute the refresh when triggered via Power Automate.

Product
Excel, Power Automate
Device & OS
not provided
Scenario
Automating Excel data connection refreshes and copying Dataverse values using a TypeScript executed via Power Automate.
Observed behavior
The script works perfectly when run directly in Excel, but the data refresh operation does nothing when invoked through a Power Automate flow.
Before you start

Ensure you have your script details, Power Automate connector configuration, run history, and workbook permissions documented before seeking further assistance.

Solution 1Recommended

Consult the Microsoft Power Platform Community

Because this involves complex cross-product interactions between Excel, Office Scripts, Dataverse, and Power Automate, specialized support is required from the Microsoft Power Platform Community.

This issue goes beyond a simple Excel formula error. The silent failure in Power Automate while the script runs perfectly on the desktop indicates an environment, permission, or connector limitation specific to Microsoft's cloud automation ecosystem.

1
Gather script information

Compile all relevant information, including your full TypeScript code, connector settings, and workbook details.

2
Export run history

Take screenshots of your Power Automate run history, paying close attention to any skipped steps, silent failures, or warnings.

3
Visit the community forum

Navigate to the official Microsoft Power Platform Community forums.

4
Post a detailed query

Post your issue in the Power Automate section, clearly stating your refresh method, account permissions, Dataverse setup, and any error outputs.

Crucial detail to include: Be sure to mention that the script works locally but fails in the cloud flow, as this helps support staff isolate execution environment issues.

Frequently Asked Questions

Why does my Office Script work in Excel but not in Power Automate?

This often happens due to differences in execution environments. Power Automate runs the script in the background on a server, which may not support certain client-side refresh methods, or it might encounter permission and timeout restrictions not present during manual desktop execution.

Can I trigger an Excel data refresh without using Office Scripts?

Yes, depending on your data source, you can sometimes use Power Automate's built-in Excel Online connectors to update rows, or utilize Power BI integration if you are trying to refresh complex datasets and pivot tables directly from cloud sources.

Does WPS Office support Microsoft Office Scripts?

WPS Office supports standard JavaScript/TypeScript-based macros and Excel VBA (Visual Basic for Applications) depending on the version. However, Microsoft-specific cloud integrations like Office Scripts built exclusively for Power Automate are limited to the Microsoft ecosystem.
