How does the JSON Diff checker work?

It automatically parses and beautifies both JSON inputs, then compares them line-by-line to generate a GitHub-style diff showing exactly what was added or removed.

Will it tell me if my JSON is invalid?

Yes. The tool instantly validates the syntax of both inputs and displays the exact parsing error if the JSON is malformed.

It automatically formats the JSON and highlights additions in green and deletions in red.
