JSON en PDF

Readable JSON, On Paper

JSON is built for machines. The moment you need to share an API response with a colleague, archive a config file, or attach a data export to a report, a wall of unformatted braces stops being useful. This tool parses your JSON, pretty-prints it with proper nesting indentation, and renders it to a PDF with real syntax highlighting — keys, strings, numbers, booleans and null each get their own color, the way your editor shows them.

Paste JSON straight into the editor or import up to ten .json files at once. The editor highlights as you type and flags invalid JSON with the exact line and column, so you fix the input before converting instead of discovering the problem in the output.

What You Can Control

The output is a code-style document, so the options are about how that code reads on the page.

Built for API Responses, Configs and Exports

Documenting an endpoint? Paste the response body and get a highlighted PDF you can drop into a spec or email. Auditing a deployment? Convert the JSON config to a paginated document with line numbers you can cite in a review. Collecting data exports? Batch-convert a folder of .json files into shareable PDFs in one pass.

Large files are paginated automatically — long lines wrap at token boundaries instead of spilling off the page, and continuation lines are indented so the structure stays visible.

How It Compares

Plenty of tools turn JSON into a table or plain text. This one keeps the code view.

Your Data Never Leaves Your Device

JSON files tend to carry exactly the data you should not hand to a stranger — API payloads with customer records, configs with internal hostnames, exports with credentials someone forgot to strip. Most online converters upload your file to a server to process it.

OxygenPDF parses and renders everything in your browser. Nothing is sent anywhere, and closing the tab wipes the data. If your JSON is covered by an NDA, GDPR, or plain common sense, client-side conversion is the safe default.
