About JSON Formatter & Validator — SolveBar

Format, beautify, minify and validate JSON right in a toolbar popup. Paste any JSON and see it pretty-printed with 2-space, 4-space or tab indentation, a one-click minify, and instant valid / invalid feedback. One-click copy of the result. Everything runs locally in your browser — no data is uploaded, nothing is stored, no analytics, no tracking. Safe for API keys, tokens and private payloads.
