About JSON Crack

JSON Crack solves a common developer pain point: understanding deeply nested data structures. Whether you are debugging an API response or exploring a configuration file, the tool renders any structured data as a visual graph where each key-value pair and nested object becomes a connected node. You can collapse and expand sections, search for keys or values, and click any node to see its full JSON path.

The tool supports JSON, YAML, XML, CSV, and TOML formats. An integrated editor lets you modify data and see the graph update in real time. The comparison mode diffs two JSON documents with visual highlighting of changes. JSON Crack can generate shareable image exports for documentation.

JSON Crack is open source under Apache 2.0 with over 24,000 GitHub stars. The React component can be embedded in any web application. VS Code and JetBrains extensions bring visualization into the development workflow. All processing happens in the browser—nothing is sent to external servers.
