Did you know?
We process your documents privately in local sandbox storage. Your actual data remains in your browser tab. We never log, view, or store file contents.
Printing JSON so people can read it
Turn a JSON document into a paginated PDF with consistent indentation — useful for attaching an API response to a bug report, sharing a configuration with a reviewer or keeping a snapshot of data on file.
Structure you can follow on paper
Nested objects and arrays are indented so the hierarchy stays visible, and long documents flow across as many pages as they need.
Catch errors first
For large or hand-edited JSON, run it through the JSON formatter before converting; it pinpoints problems like trailing commas that are easy to miss by eye.
Strip secrets before sharing
API responses often contain tokens, email addresses or internal IDs. The PDF contains exactly what you paste, so remove anything that should not leave your team.
Generated in the browser
The PDF is built locally; the JSON is not transmitted.
