The JSON Formatter is an all-in-one workstation for malformed payload repair, structured exploration, query extraction, schema workflows, and model generation. Everything runs locally in your browser.

Paste strict JSON, JSONC, or JSON5, then switch between tree, table, graph, query, and schema tabs to inspect and transform complex data quickly. You can also generate TypeScript, Python, Go, and Java model stubs from the same input.
