What's Good
Apache-2.0 (AykutSarac/jsoncrack.com), release v5.0.0 (2026-03-11), with commits into September 2026. Converts between formats such as JSON to CSV or YAML, generates JSON Schema, and exports images. There is a VS Code extension, and you can self-host the web app. ★~44.5k.
The Catch
Large files get slow in the graph view. The maintainer also builds ToDiagram, a paid product, and the open-source app gets fewer releases. It is a viewer and converter, not a full data tool.
Verdict
The quickest way to make sense of an unfamiliar JSON blob.
