No, Rosetta translates text while preserving formulas, calculations, formatting, merged cells, charts, images, and dropdown menus.

### What API key is required to use Rosetta?

You need a Claude API key from Anthropic to use the service.

You can add domain-specific context to the command to help the AI understand specialized terminology.
