Ready to download?The default is UTF-8 BOM, which opens cleanly in Excel.

Excel still shows garbled text?

Keep “UTF-8 with BOM” selected. The marker at the start of the file helps Excel recognize the encoding.

Is the preview still wrong?

Change the source encoding to GBK, Big5, Shift-JIS or EUC-KR until the preview looks right.

Seeing ? or �?

The original characters may already be gone. Encoding conversion cannot restore text that was replaced during export.
