JSON Diff Checker
Compare two JSON values structurally and report changed paths.
Method
Both inputs are parsed as JSON. Objects are compared by key, arrays by index, and primitive values by both type and value. Differences are reported using root-based paths such as $.count or $.items[1].
Worked example
Comparing {“count”:1} with {“count”:2,”live”:true} reports a changed $.count path and an added $.live path.

Limitations
Array order is significant. This tool does not perform semantic set comparison, JSON Patch generation, or schema-aware equivalence.
