What is JSON Crack?

JSON Crack is a free, open-source tool that turns JSON, YAML, CSV and XML into an interactive graph, making nested data much easier to read. You can format, validate and query data, and export the visual as an image, all in the browser.

Pros: what JSON Crack does well

  • Clear graph view of nested data
  • Supports JSON, YAML, CSV and XML
  • Export diagrams as images

Cons: where it falls short

  • Very large files can slow down
  • Advanced features point to a paid sister product

Who JSON Crack is for

Developers and analysts who need to understand complex API responses or config files.

Who can skip it

People who rarely work with structured data.
