Using Notepad++
This will fix the corrupted CSV file saved by Excel and re-save it in the proper encoding.
- Export CSV from Excel
- Load into Notepad++
- Fix encoding
- Save
Excel saves in CP-1252 / Windows-1252. Open the CSV file in Notepad++. Select
Encoding > Character Sets > Western European > Windows-1252
Then
Encoding > Convert to UTF-8
File > Save
First tell Notepad++ the encoding, then convert. Some of these other answers are converting without setting the proper encoding first, mangling the file even more. They would turn what should be ’
into 達
. If your character does not fit into CP-1252 then it was already lost when it was saved as CSV. Use another answer for that.
