Traduire JSON en ligne: clés et imbrications

Need to translate a JSON file without breaking your app's data structure? ForgeFile is an AI-powered JSON translator that converts your localization files into 100+ languages while preserving every key, placeholder, array, and nested object. Whether it's i18n strings, API responses, or config data, your translated JSON is valid, diff-friendly, and ready for production.

How ForgeFile Translates JSON Files

Our translation engine understands JSON semantics. When you translate a JSON file, ForgeFile:

• Parses the full object tree - keys, values, arrays, and nested structures
• Translates only string values using context-aware AI that understands UI text and app terminology
• Preserves keys, placeholders ({name}, {{count}}, %s), ICU patterns, and variable references

The result is a valid JSON file you can drop directly into your project - no broken syntax, no missing keys, no corrupted placeholders.

Placeholder-Safe & Developer-Friendly Output

ForgeFile is built for developer workflows:

• Keys are never translated or modified - only string values are localized
• Placeholders like {username}, {{count}}, %d, and $t() references are preserved
• ICU MessageFormat patterns (plurals, selects, numbers) stay valid
• Nested objects and arrays maintain their exact structure and depth
• Output is diff-friendly with consistent formatting for clean version control

Built for App Localization, APIs & SaaS Products

ForgeFile handles the JSON files development teams work with every day:

• i18n & App Localization - translate React, Vue, Angular, and Next.js localization files (i18next, react-intl, vue-i18n)
