Very major bugs
Response from developer
Sorry to hear that you had an issue adding your data source. You can indeed upload CSVs into Zing. You may have experienced an issue reading in a CSV if the header field length is >59 characters, or there are duplicate column headers (or if the first 59 characters of a column are duplicate with the first 59 characters of another column). We've added clearer messages on the import step for CSVs which should make this easier to understand at import time so any issues can be corrected there. We're happy to help - just email us support@getzingdata.com with the specifics and we'll get you up and running!
