Export PDF tables as structured JSON with a tables collection for downstream processing. This flow extracts table data rather than a full-page OCR transcript.
An empty collection means no tables were detected. Validate the extracted rows before importing them; use OCR JSON for page text and recognition blocks.

When to use it
Use it when a developer or an automated workflow needs table data from PDFs, for example to import supplier price lists or check reports on a schedule.

Common questions
What does an empty result mean?
The tables collection is empty when no tables were detected in the PDF.
Are numbers typed as numbers?
Cells are kept as text as they appear, so your code decides how to parse numbers and dates.
Does it include page numbers?
Tables are listed in page order. Check the JSON for the page each one came from before relying on it.
Can I run it on many PDFs?
Yes. Upload a batch and each PDF produces its own JSON file.
