❓ Troubleshooting

Tag Information is Blank

Cause: No tag information is embedded in the file.

Explanation:

If tags are not set in the original music file, the corresponding fields will be blank
This is not a tool issue but because the file itself has no tag information

Some Files Are Not Processed

Cause: The file is corrupted or in an unsupported format.

Solution:

Check the error message
Verify if the file can be played normally

CSV File is Garbled When Opened in Excel

Cause: Old version of Excel or configuration issue.

Solution:

The file is saved with UTF-8 BOM, so it normally doesn't get garbled
In Excel, import via "Data" → "From Text" and specify "UTF-8" encoding
