Fix CSV Encoding (UTF-8 vs. CP949) in One Click
Stop garbled text and open CSV files correctly on Windows and Excel.
Why CSV text breaks
Windows and Excel often default to CP949, while many tools export UTF-8. A mismatch causes broken characters.
How to fix it
Detect the encoding, convert it to the target format, and re-open in Excel. If you share globally, UTF-8 is the safest default.
