Connects Claude to an Excel translation pipeline that preserves formulas, formatting, and merged cells while translating content via Claude's API. Exposes operations to translate entire workbooks or specific sheets, estimate costs before processing, preview translatable cells, and list available sheets. The translation engine batches cells together for efficiency and supports domain context to improve accuracy for specialized terminology. You'd reach for this when you need to localize spreadsheets without manually reconstructing layouts or breaking cell references. The underlying API handles both streaming progress updates via SSE and standard file uploads, so you can track long translations in real time or fire and forget for smaller files.
