What Is JSON to iOS .strings?

The iOS .strings file format is Apple's standard localization format used in iOS and macOS applications. JSON to iOS .strings conversion transforms JSON translation objects into the "key" = "value"; format that Xcode and Apple's localization system natively understand.

This is used for:

  • iOS/MacOS Localization: Converting JSON translations exported from web-based localization platforms into the .strings format required by Apple Xcode projects.
  • Cross-Platform Sync: Sharing translation resources between web and native Apple apps by converting shared JSON into platform-specific .strings files.
  • CI Automation: Generating Localizable.strings files automatically from JSON translation sources during build pipelines.

How to Use JSON to iOS .strings Online

  1. Paste your JSON: Enter a JSON object with string keys and values representing your translations (e.g., {"greeting": "Hello"}).
  2. Click Convert: Press the Convert to .strings button to transform each JSON key-value pair into the "key" = "value"; format used by Apple.
  3. Copy or download: Copy the output or download it as a .strings file for direct integration into your Xcode project.

Frequently Asked Questions

How are .strings files structured in Xcode projects?

.strings files are placed inside language-specific .lproj directories (e.g., en.lproj/Localizable.strings, es.lproj/Localizable.strings). Each file contains key-value pairs where both keys and values are quoted strings separated by an equals sign and terminated with a semicolon.

Real-World Examples

Mobile development teams building apps with both React Native (which uses JSON for translations) and native Swift/SwiftUI code can use this tool to convert the shared JSON translations into .strings files. This ensures translation consistency across the entire iOS app while maintaining a single source of truth in JSON format.
