PullPDF's AI reads the entire document, identifies employee name, pay period, gross earnings, and exports a clean .json file — ready to use in API integration.

Why Extract Pay Stub Data to JSON?

Mortgage lenders and property managers require pay stub verification. Each employer uses a different format, making automated extraction nearly impossible with template-based tools. 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 paycheck stubs and earnings statements 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 pay stub: employee name, pay period, gross earnings, deductions (taxes, insurance, 401k), net pay, and YTD totals.

For batch processing, upload all your pay stubs 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 pay stub has tables that span multiple pages, PullPDF automatically merges them into one continuous table.
