List Table Extractors API Definition

Tabular data extraction plays a crucial role in document processing, enabling efficient indexing and retrieval of structured information. The List Table Extractors API allows users to query available table extractors, ensuring seamless integration with Vectara's document processing pipeline. This API helps users identify the extractors supported by the platform, along with their specifications, to optimize document indexing.

Table extractors process documents to extract and structure tabular content. Users can choose from multiple extractors, each providing different extraction capabilities, or rely on the default extractor provided by Vectara.

List Table Extractors Request and Response Details​

To retrieve the available table extractors, send a GET request to /v2/table_extractors. This request returns a list of all supported table extractors, their names, descriptions, and whether they are the default extractor for document indexing.
