AI-Powered PDF to Structured JSON Conversion

Discover how AI-powered file conversion from PDF to structured JSON can revolutionize your data processing.

Parse by Conversion Tools - Document Data Extraction API

Extract structured data from PDFs, invoices, receipts, and forms with a single API call.

Convert PDF to JSON online. Upload a PDF and the AI returns one JSON file that follows the structure of the document: tables become lists of rows keyed by their column names, headings become nested sections, and details like dates, document numbers and totals become named fields.

That is the difference from a plain text dump of the page. The result is data you can load into a script, a database or a spreadsheet right away, without cleaning it up first. It works on scanned PDFs and photos of documents too.

How to Convert PDF to JSON

Sign in, or create a free account. Every account gets 100 AI credits each month, enough for 10 pages.
Choose your PDF, or a photo or scan of a document.
Click "Run Conversion" and download your .json file.

Each page uses 10 credits. If your credits run out partway through a long PDF, you get the pages that were converted and a note telling you how many of the total that is. More credits can be bought at any time.

What the JSON Looks Like

Here is the kind of result you get from a one-page invoice. The header details become fields, and the table of items becomes a list with one object per row:

json

{
  "invoice_number": "INV-2026-0157",
  "invoice_date": "2026-05-28",
  "vendor": "Acme Supplies GmbH",
  "currency": "EUR",
  "line_items": [
    { "description": "A4 paper (500 sheets)", "quantity": 6, "unit_price": 12.5, "amount": 75.0 },
    { "description": "Ballpoint pens (box)", "quantity": 4, "unit_price": 8.2, "amount": 32.8 }
  ],
  "subtotal": 107.8,
  "tax": 20.48,
  "total": 128.28
}

Tables: every row becomes an object with the same keys, taken from the column headers.
Text documents: reports, contracts and papers come out as nested sections, with headings, paragraphs and lists in their original order.
Document details: dates, document and reference numbers, names and totals are kept as their own fields, not buried in a block of text.

The key names come from your document, so two different invoices can use slightly different names. If you need the same fields every time, for example to feed a database or an app, use Parse by Conversion Tools, where you choose the fields once and every document comes back in that shape.

Which PDFs Work Best

Invoices, receipts, purchase orders and bank statements: header fields plus item or transaction tables.
Forms: each label and its filled-in value become a field.
Reports, price lists and catalogs: tables become lists of rows, and the text around them becomes sections.
Scans and photos: scanned PDFs work, and so do JPG, PNG, WebP, TIFF, BMP and GIF images of documents. A sharp, straight photo gives the best result.

Large drawings and schematics, where the text sits inside the picture, are the hardest case and may come out incomplete.

PDF to JSON: Frequently Asked Questions

How do I convert PDF to JSON online?

Sign in, choose your PDF, click "Run Conversion" and download the .json file. A free account converts 10 pages every month.

Can I convert a scanned PDF to JSON?

Yes. Scanned PDFs and photos of documents (JPG, PNG, WebP, TIFF, BMP, GIF) are read the same way as digital PDFs, and the result has the same structure.

How much does it cost?

Each page uses 10 AI credits. Every account gets 100 free credits a month (10 pages), and credit packs cover anything beyond that.

Can I get the same JSON fields for every document?

This converter names the keys after what it finds in each document. For a fixed set of fields across many documents, through the web or an API, use Parse by Conversion Tools.

Is my document safe?

Uploads travel over encrypted HTTPS. To read the document, this converter sends its content to our AI provider; it is processed for your conversion only and not used to train AI. Your PDF and the JSON result are deleted from our servers automatically within 24 hours.
