How to Extract Purchase Order Data from PDF to JSON

To extract data from a purchase order PDF into JSON (JavaScript Object Notation), upload the document to PullPDF and describe what you need in plain English. PullPDF's AI reads the entire document, identifies PO number, vendor, ship-to address, and exports a clean .json file — ready to use in API integration. No templates, no manual field mapping, no code. Works with any purchase order format from any source.

Why Extract Purchase Order Data to JSON?

Matching purchase orders to invoices and receipts (3-way matching) is a core AP process. When PO data is locked in PDFs, the entire matching workflow becomes manual. 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 purchase orders and procurement documents 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 purchase order: PO number, vendor, ship-to address, line items (item number, description, quantity, unit price, total), delivery date, and payment terms.

For batch processing, upload all your purchase orders 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 purchase order has tables that span multiple pages, PullPDF automatically merges them into one continuous table.
