## The Hook

JSON Crack turns JSON, YAML, CSV and XML into interactive graphs or trees, so you can explore deep nested data, plus format, validate, convert and query it in the browser.

## 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.
