Can't Open Draw.io In oneDrive

Question

When I click the Open button on a .drawio file stored in SharePoint/OneDrive, I only get the screen shown in the screenshot below. It asks me to download the file, but does not give me an option to open it online.

I would like to know: How can I open and edit .drawio files directly in SharePoint/OneDrive (without downloading them to my local computer)?

Any guidance or best practices would be greatly appreciated.

You're encountering a common issue with opening .drawio files directly from OneDrive or SharePoint Online. By default, these platforms don't support previewing or editing .drawio files online. However, there are effective workarounds to open and edit your diagrams without downloading them to your local computer.

Open .drawio Files Online

Use the Diagrams.net Web App

The official Diagrams.net (formerly draw.io) web app allows you to open and edit .drawio files stored in OneDrive or SharePoint:

Navigate to https://app.diagrams.net.
Click on "File" > "Open From" > "OneDrive".
Sign in to your Microsoft account if prompted.
Browse to the location of your .drawio file and open it.

This method allows you to edit your diagrams directly in the browser without downloading them.

If you prefer working offline or need additional features, you can use the Diagrams.net desktop application:

Download and install the Diagrams.net desktop app from https://www.diagrams.net.
Open the app and sign in to your OneDrive or SharePoint account.
Navigate to your .drawio file and open it.

Any changes you make will be saved directly to your cloud storage.

Ensure…

Browser Compatibility: Ensure you're using a supported browser like Google Chrome or Microsoft Edge.

Clear Cache: Sometimes, clearing your browser's cache can resolve loading issues.

Permissions: Verify that you have the necessary permissions to access and edit the file in OneDrive or SharePoint.
