JSON Parser and Visualizer

LogJson helps you parse JSON content visually: paste JSON, inspect the tree structure, search key paths, review structure insights, and open formatted output when you need it.

Visual JSON analysis

Formatting makes JSON readable, but visual structure makes it understandable. The tree view helps developers see objects, arrays, nesting, and important branches without scrolling through raw text first.

Built for JSON workflows

Input, JSON structure visualization, key path mapping, and formatted JSON sit side by side so users can analyze API responses, logs, and configuration data without losing context.

Developer self-tests

Run lightweight checks for JSON analysis helpers.
