About the NDJSON Viewer

Columns are collected from the first thousand records, so a log file with a consistent shape lines up immediately. Records missing a field show an empty cell rather than shifting the columns.

This is the quickest way to read a structured log export without loading it into anything.

Questions people ask

Is your document uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your document never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
