I exported my channel feed to CSV format, deleted the channel feed data, then tried to import the CSV back into the channel without making any modification to the CSV file. I recieve the error "The file was not uploaded because it contains duplicate timestamps. See Channel Data Import for more information." I have confirmed that there is no duplicate timestamp data in the CSV. This seems to have been an issue in the past: https://www.mathworks.com/matlabcentral/answers/506094-can-t-import-csv-file-into-thingspeak How can I upload the CSV data back into the channel? Thanks!

How do i upload manual data for visualization to the other visualizations i have?

Hi, There is some kind of problem in one of my channels (Weather Station). Data is not showing in downloaded data file although channel is reflecting that there are already some records. I've recently changed POST procedure by GET in software, but it is not still showing data. Should I change anything else in code for data to appear? Thank you very much in advance for your support.
