Formatter, minifier, converter, decoder, parser, and generator outputs can be useful, but you are responsible for reviewing them before production use.
JWT and Base64 tools decode text for inspection. Decoding does not prove authenticity, authorization, encryption, or signature validity.
HappyFormatter is designed as a no-upload browser tool, but you remain responsible for following your employer, client, or regulatory requirements.
For production code, keep using your repository formatter, linter, type checker, tests, bundler, and CI pipeline.
