How to Show Document Names Instead of Citation Numbers in Custom Copilot
Question details
The user wants to configure a custom Copilot to display actual source document names as citation titles instead of generic reference labels like Citation-1 or Citation-2.

- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Configuring citations and references for offline knowledge sources within a custom Copilot setup.
- Observed behavior
- When utilizing offline knowledge sources, Copilot labels reference citations with generic numbers (e.g., Citation-1) rather than the source document names.
Ensure you have developer or administrative access to your Copilot Studio environment and gather the specifics of your offline knowledge source data mapping.
Consult Microsoft Q&A for Custom Configuration Guidance
Because citation rendering behavior heavily depends on specific knowledge-source data mapping and your product version, consulting Microsoft Copilot engineers is the best way to get accurate configuration steps.
Custom Copilot builds often rely on Azure AI Search or specialized offline document indexing. If metadata like document titles are not mapped correctly to the indexer's citation output, Copilot defaults to numerical labels.
Microsoft engineers actively monitor the Microsoft Q&A forums and can provide specific JSON formatting or Copilot Studio mapping instructions tailored to your version.
Navigate to the official Microsoft Q&A website and sign in with your enterprise or developer Microsoft account.
Click 'Ask a question' and describe your offline knowledge source setup, including what indexer or data connection you are currently using.
Apply the 'Microsoft Copilot' or 'Copilot Studio' tag to your post to ensure it routes to the specialized engineers who can guide you on document-name citation mapping.

Frequently Asked Questions
Why does my Custom Copilot display Citation-1 instead of the document name?
This generally happens when Copilot cannot extract the required title metadata from your offline knowledge sources. If the search index does not have a mapped 'title' property for citations, the system defaults to numbered labels.
Can I customize the citation format manually in Microsoft Copilot Studio?
Customizing the display often requires modifying how your data sources are mapped in the generative answers node or ensuring your Azure AI Search index specifically exposes document names as retrievable title fields.
Do offline knowledge sources support named citations?
Yes, they can support named citations, but this requires strict adherence to Microsoft's metadata schema configurations. If the provided metadata format is unsupported by your specific Copilot version, the fallback is a numbered citation.
