JSON (i18n)
Flat key-value JSON is the most common i18n format on the web — used by react-intl, i18next, vue-i18n, Angular and many other frameworks.
{
"welcome": "Welcome!",
"nav.home": "Home"
}
iOS .strings
.strings is the classic localization format for iOS and macOS apps (Localizable.strings). Each line is a "key" = "value"; pair, used by NSLocalizedString and String(localized:).
"welcome" = "Welcome, %@!"; "items_count" = "You have %d items";
FAQ
Is this converter free?
Yes, completely free and without registration. It is a small tool built on top of the Localization.One translation platform.
Are my files uploaded or stored anywhere?
The file is parsed in memory to produce the converted output and is never written to disk or stored. If you paste text, the same applies.
What happens to placeholders and special characters?
Placeholders like %s, %1$s, {name} or {{var}} are kept as-is. Special characters are escaped according to the rules of the target format.
