# How to Localize Product Descriptions with Copilot

Copilot brings translation directly into your i18n workflow, treating localization as a code task rather than an external handoff. Translate locale files, UI strings, and documentation without leaving your editor, then review the changes in your diff view alongside the rest of your code. This is ideal for developers who maintain localization as part of the build process, ensuring that new features ship with translations rather than accumulating a backlog of untranslated strings that need a separate localization pass.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Translate the product descriptions in products.json to French using the translate tool"
3. Copilot translates and writes the output to products-fr.json
4. Review the diff to verify translations
5. Repeat for additional languages

## Example Prompt

```
Translate all product description fields in our data/products.json file to Spanish. Write the result to data/products-es.json.
```

## Tips

- Copilot handles structured data files (JSON, CSV, YAML) natively
- Ask Copilot to preserve all non-text fields (IDs, prices, URLs) unchanged
- Use for headless CMS content that lives in your repo
