After partitioning and chunking, you can have Unstructured generate representations of each detected table in HTML markup format.

This table-to-HTML output is done by using GPT-4o, provided through OpenAI.

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.

Generate table-to-HTML output

To generate table-to-HTML output, in an Enrichment node in a workflow, for Model, select OpenAI (GPT-4o).

Make sure after you choose this provider and model, that Table to HTML is also selected.

You can change a workflow’s table description settings only through Custom workflow settings.

Table-to-HTML output is generated only when the Partitioner node in a workflow is set to use the High Res partitioning strategy. Learn more.
