Security
HappyFormatter is designed for local browser processing. That reduces exposure compared with server-side formatter APIs, but you should still follow your organization’s rules for secrets and sensitive code.
Formatter and utility actions are designed to execute in the browser tab. HappyFormatter does not provide an upload endpoint for pasted code snippets.
There is no login, workspace, saved project, or cloud history attached to the tools. That keeps the product surface intentionally small.
Formatters and converters can change whitespace, representation, or generated output. Review important output before using it in production systems.
Use private/no-upload tools for quick snippets, examples, configs, and troubleshooting.
Avoid pasting production secrets, private keys, long-lived tokens, or regulated data into any web page unless your policy allows it.
For JWTs, remember that decoding is not verification; verify signatures in a trusted server-side workflow.
For generated formatter output, run your local tests and project formatter before committing.
