CSV Encoding Fixer

CSV / EXCEL · GARBLED TEXT

Chinese characters
look broken in Excel?

The file is often readable, but Excel is using the wrong source encoding. Preview the CSV, choose GBK, Big5 or another encoding, then download an Excel-friendly UTF-8 BOM file.

Common signs of an encoding mismatch

If Chinese text turns into question marks, replacement characters, or strings such as Ã, æ, or other unexpected symbols, the CSV may be decoded with the wrong character set.

GBK / GB18030

Common in Windows exports and older Chinese business systems.

Big5 / CP950

Often used by older Traditional Chinese software and exports.

UTF-8 BOM

A practical output choice when the file needs to open cleanly in Excel.

Preview before you download

Upload the file, compare the preview with the original data, and only then download the converted CSV. If the preview is still wrong, switch the source encoding manually.

A converter can fix a decoding mismatch. It cannot recover characters that were already replaced with ? or � in the original file.
