Does it work with NDJSON (one-per-line)?

No — NDJSON is a sequence of independent objects, not a single JSON document. Wrap them in an array first: [{...},{...}].

Are line numbers included?

Yes — line numbering is on by default, which is helpful for referencing specific keys in code reviews.

How does the JSON to PDF work?

Drop a .json file (or paste a payload) and get a paginated, line-numbered PDF back. We re-format the JSON with the indent of your choice (2 spaces, 4 spaces, or tabs) so it's readable, even if the source was minified. Common uses: archiving API responses for an audit trail, sending a config snapshot to a non-technical stakeholder, or printing test fixtures for a code review.

🔒 Security & Privacy

All processing happens on your device. Your files never leave your browser, never touch our servers, and are not stored anywhere. Close the tab and the file is gone.

Frequently asked

You'll see a parse-error message identifying where the problem is. Fix it in the source and try again — the tool won't produce a PDF from invalid JSON.
