JSON i18n Format

Most i18n frameworks (react-i18next, vue-i18n, i18next) use nested JSON files. This tool flattens them to dot-notation for easy auditing. 

// en.json
{
  "common": { "ok": "OK", "cancel": "Cancel" },
  "nav": { "home": "Home" }
}

// Flattened:
common.ok = "OK"
common.cancel = "Cancel"
nav.home = "Home"
