What formats are supported for upload?

The tool strictly accepts PDF files for extraction.

Can I filter the output to only show tables?

Yes, you can use the Node Filter option to display only tables, headings, or lists.

What is the 'Use Struct Tree' option?

It tells the parser to utilize the PDF's internal structural tags, if available, to improve the accuracy of semantic extraction.

Can I extract data from specific pages only?

Yes, you can input a page range like '1,3,5-7' in the Pages field to limit the extraction to those specific pages.

Does this tool output raw JSON?

The tool generates an interactive HTML explorer view that visualizes the semantic nodes, which includes previews of the underlying JSON data.
