Why Extract Contract Data to JSON?

Legal teams review hundreds of contracts during due diligence. Extracting key terms manually is slow and error-prone, creating risk of missed obligations or non-compliance. JSON preserves hierarchical data structure — nested objects, arrays, key-value pairs. Ideal for feeding extracted PDF data into APIs, web applications, or NoSQL databases like MongoDB. By converting business contracts, service agreements, and NDAs from PDF to JSON, you eliminate manual data entry and get structured, usable data in seconds instead of minutes.

Pro Tips

Be specific in your prompt — mention the exact fields you want from your contract: parties, effective date, term/duration, payment terms, key obligations, termination clauses, governing law, and signatures.

For batch processing, upload all your contracts at once and use the same prompt — PullPDF applies it consistently to every document.

Specify your desired JSON structure in the prompt for nested output that matches your API schema.

If a contract has tables that span multiple pages, PullPDF automatically merges them into one continuous table.
