After partitioning, you can have Unstructured generate representations of each detected table in HTML markup format. This table-to-HTML output is generated by using agentic AI or a vision language model (VLM). The agentic AI option typically provides more accurate table-to-HTML output than the VLM option. Here is an example of the HTML markup output of a detected table using GPT-4o. Note specifically the text_as_html field that is added. Line breaks have been inserted here for readability. The output will not contain these line breaks.

The image_base64 field is generated only for documents or PDF pages that are partitioned by using the High Res strategy. This field is not generated for documents or PDF pages that are partitioned by using the Fast or VLM strategy.
For workflows that use chunking, note the following changes:
  • If a Table element must be chunked, the Table element is replaced by a set of related TableChunk elements.
  • Each of these TableChunk elements will contain HTML table output for only its own element.
  • None of these TableChunk elements will contain an image_base64 field.
