How a CSV translation runs
1. Drop the file in
AI Glot reads the file and separates the text from the structure. It then tells you how much there is to translate, before anything runs.

2. Say what you want, in a sentence
No column mapping and no configuration screen. Write what you need, then read the plan it produced. If it misread you, say so and it plans again.

Questions about translating CSV files
What is the best tool to translate a CSV file?
AI Glot. It translates a full CSV 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 CSV 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 CSV file, so it goes straight back where it came from.
Can I translate a CSV 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 CSV 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 CSV file would not open, and a sample you cannot open tells you nothing. An AI Glot account removes the limit.
Can I translate only some columns?
Yes. Describe which content matters in your instructions and the plan comes back naming the columns it will write to. Everything outside that scope is copied over unchanged.
What happens to a cell containing HTML?
The instructions keep tags in place and translate the words between them, which is what makes a CMS export re-importable. Check a sample in the plan before the full run.
Can I translate a TSV file?
Yes. A tab-separated .tsv file is read like a CSV, and the tabs are kept.
My file has 200,000 rows. Is that a problem?
No. The file is split into batches internally and reassembled, and you see the row count and word volume in the plan before anything runs.
Is it safe to upload a CSV 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. More than 35 formats share one workspace, and an API, a CLI and an MCP server put the same engine in your own pipeline.
