Your data files should be in CSV format as Wallet currently supports only CSV files.
Wallet only supports CSV files with the delimiter characters comma (,), semicolon (;) and hashtag (#). If your file has a delimiter character other than these, you could:
- Edit the file on MS Excel, change the delimiter character to one of the above, and save it as a CSV file.
- Make a request via this form to our developers for your delimiter character to be supported in future releases.
