How to do it
- Drop your CSV file on CSVFix.
- Check the encoding shown in the summary line and the accents in the preview.
- Tick UTF-8 BOM (for Excel).
- Click Download CSV.
Why it helps
Excel on Windows often treats a UTF-8 file without a BOM as legacy text, so characters such as é, ñ or ü are read wrongly. The BOM tells Excel the file is UTF-8.
Questions
Does the BOM change my data?
It adds three invisible bytes at the start of the file. Excel hides them.
Should I always add it?
Not always. Some programs and importers read the BOM as part of the first column name, so use it only for files meant for Excel.
Is Windows-1252 supported?
Yes. CSVFix detects it when reading, and the download is always UTF-8.
