About This Tool

What does this tool do?

A diagnostic JSON inspection utility that parses arbitrary JSON input and renders an interactive, collapsible node tree. Annotates primitive types (String, Number, Boolean, Null, Array, Object), counts child elements, and highlights exact syntax errors with line and column indicators.

When should you use it?

Use this tool to inspect complex API responses, debug JSON parse exceptions, analyze payload hierarchies, or verify JSON structure validity before processing in code.
