Paste any JSON data — get a clean, readable PDF report.
JSON (JavaScript Object Notation) is the universal data interchange format — used in APIs, configuration files, database exports, and web services. While JSON is machine-readable, it is often easier to review, share, or archive data as a formatted PDF document. Common use cases include generating API documentation samples, creating readable exports of configuration files, producing data reports for non-technical stakeholders, and debugging complex nested API responses.
Paste your JSON into the text area above — minified or pre-formatted. The server validates the JSON, prettifies it with consistent 2-space indentation using a monospaced font, and renders it as a clean PDF using WeasyPrint. The result is a professional-looking document that is easy to read, print, or share with colleagues who may not have JSON tooling available.
Ensure your JSON is valid before converting. Common issues include trailing commas, unquoted keys, and single-quoted strings — all of which are invalid in JSON. You can validate your JSON at jsonlint.com before pasting it here. Both objects ({}) and arrays ([]) are accepted as root values.
The converter accepts any valid JSON including objects, arrays, nested structures, strings, numbers, booleans, and null values. Both minified (single-line) and already-formatted JSON are supported.
Yes. The server validates that the input is well-formed JSON before converting. If your JSON contains syntax errors such as trailing commas, unquoted keys, or mismatched brackets, you will receive a descriptive error message.
Yes. JSON input supports up to 10 MB of text. For very large JSON payloads, the converter prettifies the content and it flows across multiple PDF pages for readable output.
Yes. Regardless of whether you paste minified or pre-formatted JSON, the converter always prettifies the output with consistent 2-space indentation and a monospaced font, making the PDF easy to read.
Your JSON is processed server-side and immediately discarded after the PDF is generated. We do not log, store, or analyze the content of your JSON data. All connections are encrypted via HTTPS.
