Solution 1Recommended

Create a Flow to Download an Existing Excel File from SharePoint

Use an instant cloud flow with a Power Apps trigger to fetch an Excel file from SharePoint and return its content directly to your application.

This solution outlines the standard procedure for linking a Power Apps button to a Power Automate flow, retrieving a static Excel file from a SharePoint document library, and passing the file content back to the app for the end-user.

Create an instant cloud flow

Log into Power Automate, select 'Create', choose 'Instant cloud flow' from blank, and select 'Power Apps' as your flow's trigger.

Get file content from SharePoint

Add a new action and search for 'Get file content' under SharePoint. Select your SharePoint Site Address and specify the File Identifier for the target Excel file you wish to download.

Return file response to Power Apps

Add the 'Respond to a Power App or flow' action. Create a file output variable and dynamically assign the retrieved SharePoint file content to it.

Trigger the flow in Power Apps

In Power Apps, select your download button, navigate to the 'OnSelect' property, and call your newly created flow using the syntax: 'FlowName.Run()'. Use the Download() function alongside it to capture and save the returned file data.

File Format Verification: Ensure you explicitly include the .xlsx file extension in your Power Apps download function to prevent the system from saving the file in an unrecognized format.

Solution 2

Generate and Download an Excel File with Selected Data Only

Dynamically create a new Excel workbook containing only specific worksheets or extracted data before returning it to Power Apps.

Frequently Asked Questions

Why is my downloaded Excel file corrupted when opened?

This usually occurs if the file content is not properly converted to Base64 format or if the file extension is omitted in the Power Apps download logic. Ensure you pass the correct file content format through the Power Automate response action and explicitly define the .xlsx extension.

Can I download multiple Excel files using a single Power Apps button?

Yes, but Power Apps expects a single response payload from a standard flow. You would need to configure your Power Automate flow to combine multiple Excel files into a single .zip folder using OneDrive actions or third-party connectors before returning it to the app.

Do I need premium licenses to use Excel actions in Power Automate?

Standard Excel Online (Business) and SharePoint actions are included in most base Microsoft 365 plans. However, depending on the complexity of your flow and the data volume, advanced operations or external connectors might require a standalone Power Automate Premium license.
