How to translate Word

  1. Sign in — 500 free credits a month.
  2. Drop the file and pick the language.
  3. Run Translate and download the same file, translated.

What happens to your file

The file is opened as the ZIP of XML it is; each paragraph’s text is read across its runs, translated by the Qwen 2.5 model in Fylane’s own sandbox, and written back into the paragraph’s first run — so the paragraph’s style, numbering and alignment, the pictures, tables and layout all stay. Nothing leaves the platform.

A sentence split across bold and plain runs comes back in the first run’s formatting; the metadata counts those. Up to 3 000 characters of text a run — about a page, two or three minutes on the sandbox model; a longer document is refused with the count, split it first.

Questions

How good is the translation?

A small local model: faithful on plain prose, weaker on idiom and long sentences. It is the private, formatting-keeping option, not a replacement for a translator on a contract.

Why is there a size limit?

The model runs on one CPU in the sandbox at a few words a second; 3 000 characters is two or three minutes. Longer documents are refused rather than timed out halfway.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "document.translate",
    "options": {
      "language": "en"
    }
  }'

The same operation, document.translate — A Word or PowerPoint file translated in place by the sandbox model (`language`, 16 codes): every paragraph’s words replaced, its style, numbering, layout and pictures kept; up to 3 000 characters of text a run. Runs merged where a sentence was split across formatting. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
