About JSON Crack
JSON Crack is an online viewer that turns structured data into a visual tree graph. It works with JSON, YAML, CSV and XML, and its editor is open source.
What it does
You paste or upload your data, and the tool builds an interactive graph that you can explore. You can also format and validate JSON, convert between formats such as JSON to CSV or YAML to JSON, and generate TypeScript interfaces, Go structs or JSON schemas from sample data. Graphs can be exported as PNG, JPEG or SVG images. The site also offers a VS Code extension for working with data inside your editor.
Key features
- Interactive graph view of nested data
- Format and validate JSON and YAML
- Convert between JSON, CSV, YAML and XML
- Generate TypeScript types and JSON schemas
- Export graphs as PNG, JPEG or SVG
Who it's for
Developers, analysts and anyone who needs to understand a large or messy data file quickly. It suits people who prefer a visual view of a structure to reading long nested text.
Pricing and good to know
The web editor is free to use, and the source code is on GitHub under the Apache-2.0 licence. The site says your data is not stored on its servers and that everything happens on your device. Upgrade options are listed on the site for extra features.
