ClearJSON

ClearJSON is a free, local-first JSON viewer, formatter, validator, and inspector for iPhone and iPad.

Paste JSON, open files from Files or iCloud, validate payloads, format readable output, minify compact JSON, sort keys, search paths and values, copy formatted output, and export cleaned JSON.

ClearJSON is built for everyday personal and professional use: checking API responses, reviewing config files, cleaning JSON snippets, debugging payloads, and inspecting nested data.

Privacy is the default. JSON is processed on device and is not uploaded to a server. There are no accounts, no analytics, and no tracking.

The app includes optional creator-style support through Apple In-App Purchase. Support does not unlock extra features or content.
