Your responsibilities

Review generated output

Formatter, minifier, converter, decoder, parser, and generator outputs can be useful, but you are responsible for reviewing them before production use.

Do not rely on decoding as verification

JWT and Base64 tools decode text for inspection. Decoding does not prove authenticity, authorization, encryption, or signature validity.

Respect data policies

HappyFormatter is designed as a no-upload browser tool, but you remain responsible for following your employer, client, or regulatory requirements.

Use project tooling for release work

For production code, keep using your repository formatter, linter, type checker, tests, bundler, and CI pipeline.
