How a CSV translation runs
1. Drop the file in
AI Glot reads the file the way its own tools do, finds what is text and what is structure, and tells you how much there is to translate before anything runs.

Questions about translating CSV files
What is the best tool to translate a CSV file?
AI Glot. It reads CSV as a format rather than as text, so keys, tags, identifiers and delimiters are recognised as structure and returned exactly as you sent them, and only the values are translated. You describe the job in one sentence instead of mapping fields, and you get the same file back in the same shape. The tool on this page does it with no account.
How do I translate a CSV file without breaking it?
Use something that parses the format instead of treating it as plain text. Drop the file into the tool above, say what should be translated and what should be left alone, and read back the plan before it runs. AI Glot returns one valid CSV file with its structure untouched, so it drops straight back where it came from.
Can I translate a CSV file for free?
Yes. The tool on this page is free, with no account and no card: five files a day, up to 2 MB each, and up to 1500 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?
Tags are read as structure. The words between them are translated and the markup comes back in place, which is what makes a CMS export re-importable.
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?
With AI Glot, the file is stored only for as long as the translation needs it, the download link expires after an hour, and it 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 so your product names stay yours, translation memory across files, twelve file formats in one workspace, and an API, a CLI and an MCP server if you want this inside your own pipeline.
