# Citations for Content Chunks

Verify the accuracy of AI responses grounded in your unstructured data with inline citations for content chunks. When you create a search index in Data Cloud, the index creates citations for each chunk.

Data Cloud adds these citations for unstructured data.

| PDF | Page number, file type |
| Excel | Page number, page name, and file type |
| PowerPoint | Page number, file type |

Note If you have existing search indexes, [rebuild those indexes](https://help.salesforce.com/s/articleView?id=data.c360_a_search_index_rebuild_search_index.htm&release=264.0.0&type=5 "If a Data 360 search index doesn't process properly, you can trigger a full rebuild of the index from the list page or the object record view.") for Data Cloud to add the `citation__c` field to the chunk DMO and populate it with citations.
