Markdown-Dateien (.md) in Copilot for OneDrive / Graph Data Connect

Hi everyone,

I’m currently exploring the use of Microsoft 365 Copilot with OneDrive as a personal and team knowledge base.
However, I noticed that Markdown (.md) files are not being indexed or recognized by Copilot — even when OneDrive access is granted and the files are fully visible in Microsoft Search.

Markdown is widely used for technical and structured documentation (for example, meeting notes, system specs, and transcriptions), and many of us store these files directly in OneDrive or SharePoint.
It would be extremely useful if Copilot could read and summarize Markdown files just like it does with Word, PDF, or plain-text files.

My questions are:

Is there currently any way to make Copilot index Markdown files, perhaps via Microsoft Graph or the Admin Center (for example, MIME-type mapping or content connectors)?

If not, is support for Markdown planned for Copilot in OneDrive or Graph Data Connect?

Context:
I maintain an internal knowledge base of project documentation and transcripts in Markdown stored in OneDrive.
I’d like to use Copilot to query, summarize, and cross-reference this content directly, without having to convert the files to .docx or .pdf.

Any insights, workarounds, or roadmap hints would be greatly appreciated.

Thank you in advance for your help and for all the great work you’re doing to make Copilot more versatile.

Best regards,
Nick
