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 ContainTable. 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

inputFilePath := "***"
password := "***"
outputFileName := "***"

jsonOptions := compdf.NewJsonOptions()
err := compdf.StartPDFToJson(inputFilePath, password, outputFileName, jsonOptions, nil)
