What people bring us Excel (XLSX) files for
Four jobs that come up again and again. Each one is one upload and one sentence.
A content workbook for a website build
A whole content workbook in one pass. Every sheet shares the same brief and the same glossary.
A pricing or catalogue sheet
Price lists and catalogues at full size. Numbers and formulas are not words, so AI Glot leaves them alone.
A translation hand-off sheet
Fill a target column beside the source. Your reviewer sees both languages on one row.
A multi-tab reference document
Glossaries, help text and error messages across seven tabs. One upload, not one job per tab.
Questions about translating Excel (XLSX) files
What is the best tool to translate a Excel (XLSX) file?
AI Glot. It translates a full Excel (XLSX) file in one job, at a quality you can steer with a glossary and a plain-English brief. You describe what you need. You do not map fields or split the file. The tool on this page runs it with no account.
How do I translate a Excel (XLSX) file without breaking it?
Use a tool that reads the format instead of the raw text. Upload the file above and say what to translate. Read the plan, then run it. AI Glot returns one valid Excel (XLSX) file, so it goes straight back where it came from.
Can I translate a Excel (XLSX) file for free?
Yes. The tool on this page is free. No account and no card. Five files a day, up to 2 MB each, and up to 5,000 words translated per file. Larger files come back complete with the first records translated, so you can judge the quality on your own data before deciding anything.
What happens if my Excel (XLSX) file is bigger than the free limit?
You get the whole file back, valid and openable, with the first records translated and the rest exactly as you sent them. It is deliberately not truncated: a cut-off Excel (XLSX) file would not open, and a sample you cannot open tells you nothing. An AI Glot account removes the limit.
Do my formulas survive?
Yes. A cell whose content is a formula is never a translation candidate, so the formula string itself is copied across.
What about multiple sheets?
Every sheet is read. The plan tells you which sheets and which columns hold the translatable content before you approve.
Are merged cells and styling kept?
Cell formatting and structure are preserved. AI Glot writes values, it does not rebuild the workbook.
Is it safe to upload a Excel (XLSX) file to an online translator?
AI Glot keeps the file only as long as the translation needs it. The download link expires after an hour. The file is deleted afterwards. Nothing you upload is used to train any model. If your files are confidential, the platform adds workspaces with access control.
What do I get with an AI Glot account?
No size limit and no daily limit. Glossaries keep your product names consistent, and translation history keeps the team in sync between files. Twelve formats share one workspace, and an API, a CLI and an MCP server put the same engine in your own pipeline.
Other formats
Twelve families in all, each with a workflow built around its own structure.
CSV
Translate thousands of CSV rows with your glossary and instructions applied across the whole file.
ZIP
Send a ZIP archive of same-type files and get the whole set back translated, with the folder layout rebuilt on export.
JSON
Translate the values in a JSON language file, including Flutter ARB, while every key, nesting level, and ordering stays exactly as you sent it.
