CSV is not opening in mail attachment

I have successfully received email with.csv attached, but it is not opening, saying "We couldn't open this workbook in the browser."

The issue you're encountering with the CSV file not opening in Excel from an email attachment could be related to the encoding or format of the CSV file. In the Superset codebase, CSV files are saved with the encoding "utf8" before being sent as email attachments ^[1].

Here are a few things you can check or try:

1. Encoding Issues: Ensure that the CSV file is correctly encoded in UTF-8. Sometimes, Excel has trouble opening UTF-8 encoded files directly, especially if there are special characters.

2. File Association: Make sure that the file is being recognized as a CSV by your system. Sometimes, the file extension might not be correctly associated with Excel.

3. Open in Desktop App: As suggested by the error message, try opening the file in the Excel desktop application instead of the browser. This can sometimes bypass issues related to browser-based Excel viewers.

4. Check for Corruption: Ensure that the file is not corrupted. You can try downloading the attachment and opening it with a text editor to see if the content is readable.

If these steps don't resolve the issue, you might want to verify if there are any specific settings or configurations in your email client or Excel that could be affecting the opening of CSV files.
