Extract PDF to JSON ​

Overview ​

Extract text, tables, and images from PDF documents to a 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, table content is extracted from PDFs together with table structure; otherwise, table content is 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.

Sample ​

Full sample code which illustrates the text extraction capabilities.

python
input_file_path = "***"
password = "***"
output_file_name = "***"

json_options = ConvertOptions()
error = CPDFConversion.start_pdf_to_json(input_file_path, password, output_file_name, json_options)
