Extract PDF To JSON

Overview

Extract text, tables and images from PDF documents to Json file.

Standard table and non-standard table

Commonly, tables can be divided into two categories: standard tables and non-standard tables. The specific definitions are as follows:

• Standard table: The table border and the inner lines of the table are complete and clear. There is no need to manually add table lines to divide the table content.
• Non-Standard Tables: Tables lacking borders or clear inner lines, requiring manual additions of table lines to separate contents.

Table Extraction Option

ComPDF Conversion SDK supports the option json_contain_table, when enabled, will extract table content from PDFs and output the table structure; otherwise, table content will be treated as regular text.

Notice

• Without enabling AI layout analysis or OCR options, tables in the original PDF cannot be extracted. It is recommended to enable AI layout analysis or OCR for high-precision table recognition.
