Import and Translate JSON

Use this guide when you already have translation JSON and want Lezu to fill in missing target languages.

Source File

Example en.json:

{
  "nav": {
    "home": "Home",
    "pricing": "Pricing"
  },
  "checkout": {
    "pay": "Pay now",
    "items": "You have {count} items"
  }
}

Import With Translation

POST /v1/i18n/projects/project_123/import
Authorization: ApiKey lez_...
Content-Type: application/json

{
  "locale": "en",
  "targetLocales": ["nl", "fr", "de"],
  "translateMissing": true,
  "content": {
    "nav": {
      "home": "Home",
      "pricing": "Pricing"
    },
    "checkout": {
      "pay": "Pay now",
      "items": "You have {count} items"
    }
  }
}

What Lezu Does

• Creates keys such as nav.home and checkout.items.
• Stores the English source values.
• Creates Dutch, French, and German translations for missing values.
• Preserves placeholders such as {count}.
• Records translation usage for the account.
