Formula names, named ranges, sheet names referenced in formulas and data-validation lists all break a workbook if translated, and locale decimal and date handling breaks it quietly.[Vitra.ai Universe](https://www.vitra.ai/platform) translates in place, then checks what it changed. ## The risk is arithmetic, not language A spreadsheet is a small program with words on top. Translating the words is easy; the failure mode is translating something the program depends on. Break a label and someone squints. Break a named range and the workbook returns errors on every dependent sheet. ## What to translate and what to protect Cell content Translate Column and row headers Yes Free-text notes and comments Yes Chart titles and axis labels Yes Formula function names No Named ranges No Sheet names referenced in formulas No Data-validation list values Only with the validation rule Lookup keys used by VLOOKUP or XLOOKUP No Lookup keys are the quiet one. Translate the text in column A and every `VLOOKUP` pointed at it stops matching, so the sheet fills with `#N/A` and somebody spends an afternoon working out why. Data-validation lists fail the same way: translate the dropdown values and the rule that validates them no longer recognises what users pick. ## Locale breaks more files than language Decimal separators differ. A German locale reads `1.234` as one thousand two hundred and thirty-four, and an English one reads it as roughly one and a quarter. Date order differs the same way, so `03/04` is two different days depending on who opens it. Neither is a translation problem and both arrive with translated files, which is why a workbook should be checked against the destination locale rather than only proofread. ## Doing it without touching the logic [Document translation](https://www.vitra.ai/features/document-translation) works on the workbook structure, so formulas, named ranges and validation rules stay addressable while the labels change around them. Then [quality control](https://www.vitra.ai/features/quality-control) runs the checks on the output — proofreading, a back-translation comparison for anything carrying a claim or a condition, and a region-aware pass — and terminology stays pinned through [translation memory](https://www.vitra.ai/features/translation-memory), so a column header matches the [document](https://www.vitra.ai/general/how-to-translate-a-word-document) and the [deck](https://www.vitra.ai/general/how-to-translate-a-powerpoint) reporting from it. Open the translated file once in the destination locale before sending it. That single check catches most of what proofreading cannot. Where the numbers are product specifications, formatting carries more risk than wording — [spec sheet translation](https://www.vitra.ai/consumer-electronics/electronics-spec-translation). ## FAQ **What should not be translated in an Excel file?** Formula function names, named ranges, sheet names referenced in formulas, and any text used as a lookup key. Translating a lookup key breaks every VLOOKUP or XLOOKUP pointing at it. **Why does a translated spreadsheet return #N/A errors?** Usually because text in a lookup column was translated while the formulas referencing it were not. The lookup no longer finds a match, so every dependent cell returns an error. **What locale problems affect translated spreadsheets?** Decimal separators and date order. A German locale reads 1.234 as one thousand two hundred and thirty-four where an English one reads about one and a quarter, and 03/04 is two different dates. **How should a translated workbook be checked?** Open it in the destination locale before sending. Proofreading catches wording, but only opening the file where it will be used catches decimal, date and validation problems.
