What is document to JSON conversion?
Document to JSON conversion is the automated process of extracting structured data from any document format (invoices, receipts, contracts, forms, and scanned paperwork) and returning it as clean, typed JSON. The output is immediately usable in databases, APIs, and automation workflows without additional processing.
Parselyze integrates OCR internally, so you submit the original document file and receive structured JSON back. You define the fields you want once in the Template Builder; the AI handles the rest across any document variant or layout.
How to convert a document to JSON
Instead of building custom parsing logic, developers can send documents to the Parselyze document parsing API and receive structured JSON data in return.
Upload a document
Send your document to Parselyze via our API. You can upload any document, whether it's a digital file or a scanned document.
Fields are detected
Parselyze analyzes the document structure and detects fields to extract structured data from documents based on the provided template.
Receive structured JSON
Structured JSON data is returned via API or webhook.

Frequently asked questions
Everything you need to know about document to JSON conversion.
What is document to JSON conversion?
Document to JSON conversion is the automated process of extracting structured data from documents — such as invoices, receipts, contracts, and forms — and returning it as clean JSON. Parselyze handles OCR internally and maps the extracted content to your predefined field schema.
What document types are supported?
Parselyze supports invoices, receipts, contracts, forms, financial reports, scanned paperwork, and any document with structured content. If it has fields you can identify visually, Parselyze can extract them.
How long does document to JSON conversion take?
Most documents are processed in under 5 seconds via the synchronous API. For large volumes, use the async job queue and receive results via webhook as each document completes.
Do I need to train a model on my documents?
No. Define your extraction fields once in the Template Builder or use the AI Template Wizard to auto-generate a template from a sample document. No model training or data labeling required.
How do I define which fields to extract?
Use the Template Builder in the Parselyze dashboard to specify the fields, their types, and how they should appear in the JSON response. The AI Template Wizard can auto-detect fields from a sample document in seconds.
Can I process documents in bulk?
Yes. Use the async job queue to submit batches of documents and receive structured JSON results via webhook as each one completes. You can also upload ZIP archives containing multiple documents in a single API request.
