ExcelTranslator

ExcelTranslator.ai is an AI-powered translation tool built specifically for spreadsheets. Most people who need to translate an Excel file end up with one of two bad options: copying cells into Google Translate and pasting them back one by one, or running the whole workbook through a generic document translator that returns a file with broken formulas, shifted columns and lost formatting. Fixing that afterwards often takes longer than the translation itself.

ExcelTranslator.ai solves the specific problem of translating spreadsheet content without touching spreadsheet structure. You upload an XLSX, XLS or CSV file, choose the target language, and the tool translates the text in cells, headers, sheet names and comments while leaving formulas, cell references, charts, number formats, conditional formatting, column widths and styling exactly as they were. Multi-sheet workbooks are handled sheet by sheet, so a 12-tab financial model comes back with all 12 tabs intact and still calculating.

The tool supports over 100 languages and is built on modern AI translation models, which means it handles context better than word-for-word engines — a column header like "Balance" is translated according to how it is used in a financial sheet rather than in isolation. For teams that need consistent terminology, translated output stays consistent across the whole workbook rather than varying cell by cell.

Typical use cases include: sharing financial reports and budgets with overseas offices, localising product catalogues and price lists, preparing multilingual inventory or logistics spreadsheets, translating survey results for analysis, and handing localised data files to clients or regulators. It is used by finance and operations teams, translators and localisation managers, e-commerce sellers working across markets, and anyone who regularly receives spreadsheets in a language they do not read.

Everything runs in the browser — there is nothing to install, no Excel add-in to configure and no macro to enable. Files are processed and returned as a downloadable spreadsheet in the same format you uploaded. A free tier is available so you can run a real file through it before deciding whether to pay, and the interface is available in eleven languages including English, Japanese, German, Spanish, French, Italian, Dutch, Polish, Portuguese, Korean and Turkish.

Alongside the translator, the site publishes practical guides on translating in Excel — covering the built-in TRANSLATE function and its limits, the Review-tab translator, Google Sheets workarounds, and when a full-file tool is the better choice — so users can pick the right method for their situation rather than being pushed toward one answer.
