Pingboard's CSV import tools require CSV files with UTF-8 encoding. If your CSV file isn't saved with UTF-8 encoding, we may not be able to process the file or you may run into other errors.
To save a CSV file with UTF-8 encoding in Excel (on a Windows computer):
Click Choose File->Save As from the menu.
In the "Save as type" dropdown, select
Comma Separated Values (*.csv).Select Web Options from the Tools... dropdown at the bottom of the dialog box.
Select the Encoding tab.
In the "Save this document as:" dropdown, select Unicode (UTF-8).
If you're using a Mac, the best option is to open and export the file as a CSV using Apple Numbers or Google Sheets instead.
