Rules & checks

Parses INI client-side to surface malformed lines.

Reports counts of sections and keys when valid.

No data is uploaded or persisted.

When to use it

  • Check INI before committing app or CLI config files
  • Validate snippets from user input in forms
  • Quick pre-commit sanity check for legacy INI-based configs

Tips

  • Keep key/value pairs on single lines with '=' separators
  • Group related settings under sections for clarity

Examples

Valid config

  • [server]
  • port=8080
  • host=localhost

Malformed line

  • [server]
  • port 8080 -> parser flags missing '='

FAQs

Do you store my config?
No. Validation is entirely in-browser and clears on refresh.
Do you enforce schemas?
No. This checks INI syntax only; add schema checks in CI/CD.
