About JSON Complexity Analyzer
JSON Complexity Analyzer computes a complexity score from depth, average branching, and node count, then tiers it (simple → very complex). Useful for comparing structures and finding overly intricate JSON.
The score is heuristic — most useful for comparing several documents, not as an absolute number.
FAQ
Is my data sent to a server?
No. The entire analysis runs in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
How is this analyzer different from a parser, validator, or viewer?
An analyzer produces an insight report — metrics, statistics, warnings, and recommendations — to help you judge the quality or characteristics of the input. A parser breaks it into structure, a validator gives a valid/invalid verdict, and a viewer just displays it. An analyzer focuses on "how good / what are its characteristics".
