JSON Shape Analyzer
Analyze and visualize the structure of JSON data
Paste a JSON blob and get a visual map of its structure. Objects, arrays, strings, numbers, and booleans each get their own shape and color, nested recursively so you can see the overall architecture at a glance.
It also generates a complexity score and an inferred TypeScript type definition, which can be useful when working with unfamiliar API responses or data files.
Nothing is stored — paste, analyze, close. Your data stays in your browser.
