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 generation happens only when the Partitioner node in a workflow is set to use the High Res partitioning strategy and the workflow also contains a table-to-HTML enrichment node.

Setting the Partitioner node to use Auto, VLM, or Fast in a workflow that also contains a table-to-HTML enrichment node will not generate any table-to-HTML output, and it could also cause the workflow to stop running or produce unexpected results.

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