JSON Translate AI — Preserve Keys & Structure

Translate JSON locale files with AI while keeping every key path, bracket, and placeholder intact. Built for React i18n, Vue i18n, Flutter arb exports, and mobile app localization pipelines.

Unlike generic chatbots, Routara validates JSON structure after each run, strips accidental code fences, and retries once with a repair prompt if keys drift — output is ready for CI/CD and GitHub Actions.

Why teams use Routara for JSON i18n

  • Structure validation: every JSON key path must match the source; failed runs auto-repair once.
  • File upload & download: drag a .json file in, export translated output with one click.
  • Side-by-side diff: compare input and output before committing locale bundles.
  • Batch translation: process up to 5 files per run (10 for VIP) with per-file validation.
  • GitHub Action: automate JSON locale translation in pull requests with structure checks.

How to translate JSON with AI

  1. Paste JSON or upload a .json file. Add Target: es (or any locale) on the first line.
  2. Sign in with a free account — verified users get 30 runs per tool per day.
  3. Click Run. Review the diff view and validation badge, then download the translated file.
  4. Optional: use the translate-json GitHub Action to run the same pipeline in CI.

JSON Translate AI — FAQ

Common questions about translating JSON files with AI while preserving keys and structure.

How do I translate a JSON file using AI without breaking keys?

Paste your JSON into Routara, add Target: es (or any locale) on the first line, and run the tool. Our json translate ai prompt instructs the model to modify only string values — object keys, array order, brackets, and placeholders like {{name}} stay unchanged.

Does this JSON i18n translator preserve nested objects and arrays?

Yes. Nested structures, indentation, escape sequences, and ICU-style placeholders are kept. The output is valid JSON suitable for React i18n, Vue i18n, Flutter arb exports, and mobile app locale bundles.

Is the JSON translate AI tool free?

Basic tool: 30 free runs per tool per day after email verification (3/day if unverified). Basic VIP unlocks unlimited runs. Sign in — no credit card required for the free quota.

What is the difference between ChatGPT and a dedicated JSON localization tool?

General chatbots often rename keys or break syntax. Routara validates that every JSON key path is preserved, auto-strips code fences, and retries once with a repair prompt if structure fails — output is machine-readable for CI/CD pipelines.

Which target languages are supported?

Any language you specify with Target: on line 1 (e.g. Target: ja, Target: de, Target: pt). The UI is available in 10 languages; JSON value translation itself supports all major locales.
