FAQ
What is key information extraction (KIE)?
KIE extracts specific fields from documents into structured outputs, so you can reuse the results in spreadsheets, databases, or downstream workflows.

How do I review the extraction results?
You can review results in JSON view or table view to validate fields and scan values quickly.
Can I export the extracted data?
