About CSV to UTF-8

A CSV exported from Korean, Japanese, Russian or Chinese Excel or a bank shows garbled characters in Google Sheets, Numbers or a database import? Upload it: we detect the code page (EUC-KR/CP949, Shift-JIS, Windows-1251, KOI8-R, GB18030, Windows-1252…) and give you the same CSV in UTF-8 – with a BOM so Excel opens it correctly too.

Frequently asked questions

Why does my CSV show broken characters (�, 占쏙옙, пр)?

The file was saved in an old regional code page – EUC-KR/CP949 (Korean Excel), Shift-JIS (Japanese Excel), Windows-1251 (Russian), GB18030 (Chinese) or Windows-1252 – but your app reads it as UTF-8. We detect the code page and re-save the file as UTF-8, which every app reads correctly.

Does it change my data?

No. Only the text encoding changes. Columns, separators and line breaks stay exactly as they are.

Is my document kept?

No. Files travel over an encrypted HTTPS connection, are converted automatically and are permanently deleted after 1 hour. Nobody looks at them and they are never used for AI training.

Is CSV to UTF-8 free?

Yes – completely free, with no account, no daily limit and no watermark.

Are my files safe?

Files are sent over an encrypted HTTPS connection, processed automatically by our servers, never shared and permanently deleted after 1 hour. Nobody looks at your documents.

Do I need to install software or sign up?

No. It works in any browser on Windows, Mac, iPhone and Android. No account needed.

Is there a watermark?

Never. Your converted files are clean, with no watermark or branding.
