What does the JSON output structure look like?

The output is a JSON object with top-level keys for 'metadata' (title, author, dates, etc.), 'pages' (array of page objects each containing text content and dimensions), and optionally 'tables' (extracted tabular data as arrays). The schema is consistent across all PDFs so you can build reliable integrations.

Can I use this output in an automated data pipeline?

Yes. The JSON output follows a consistent schema designed for programmatic consumption. You can feed it into ETL pipelines, search indexers, document management systems, or any application that accepts JSON input. The structured format makes it easy to query specific fields or pages.

Does it extract images or just text?

The tool focuses on text content, metadata, and tabular data. Image data is not included in the JSON output. If you need to extract images, use the Extract Images tool instead. The JSON output does include information about image positions and dimensions on each page.

How does it handle multi-language PDFs?

Text is extracted as Unicode, supporting all languages and character sets present in the PDF. The JSON output preserves the original text encoding, including right-to-left scripts, CJK characters, and special symbols.
