What export formats are supported?

You can export extracted tables as structured JSON, flat CSV, or HTML tables.

Can I extract tables from specific pages only?

Yes, you can specify a page range (e.g., 1,3,5-7) to limit extraction to specific parts of the document.

What is the difference between JSON and CSV output?

JSON retains metadata like page numbers, bounding boxes, and grid structure. CSV flattens the data into a simple table, page, row, column, and value format.

What does the Use Struct Tree option do?

It leverages the internal structural tags of the PDF (if available) to improve the accuracy of table boundary detection.

What are the table detection methods?

You can choose between Default and Cluster methods. The Cluster method groups text elements based on spatial proximity to identify table grids.
