About JSON Analyzer
JSON Analyzer dissects a JSON document into a full report: node count, maximum depth, value-type distribution (object/array/string/number/boolean/null), total & unique key counts, and raw vs minified size.
It also gives warnings (e.g. excessive depth, too many nulls) and recommendations (e.g. potential minify savings). Unlike a validator that only judges valid/invalid.
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".
