About JSON Schema Analyzer
JSON Schema Analyzer inspects a JSON Schema and reports the property count, required fields, references ($ref), definitions ($defs/definitions), draft version, and depth. Good for judging a schema's coverage and intricacy.
It gives recommendations like adding "$schema" or marking required fields when missing.
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".
