Supported File Types

Raw document types

The upload endpoint supports several raw document types. Vectara extracts text from these documents and sections them as best it can. This provides a convenient way to index text, yet the caller has less control compared to when providing the Document proto message themselves. The following raw document types are supported:

• Commonmark / Markdown (md extension).
• PDF/A (pdf).
• Open Office (odt).
• Microsoft Word (doc, docx).
• Microsoft Powerpoint (ppt, pptx).
• Text files (txt).
• HTML files (.html).
• LXML files (.lxml).
• RTF files (.rtf).
• ePUB files (.epub).
• Email files conforming to RFC 822.

Semi-structured documents

In addition, the upload endpoint supports sending semi-structured documents through this endpoint that reflect a Document proto message. Those can be sent in the following formats:

• pb: Contains binary serialized Document proto message.

• pbtxt: Contains Document proto message in proto text format.

• json: Contains Document proto message in json text format.
