Adarsh_Murthy on Can't use data from thingSpeakRead to parse comma delimited values

Hi, 

thingSpeakRead() by default returns data back as a numeric array. For your case, since the data on the ThingSpeak channel is a string, you should use the 'OutputFormat' names parameter to request for data back as a table:

data = thingSpeakRead(readChannelID,'ReadKey', readAPIKey,'NumPoints', 1, 'Fields', [1], 'OutputFormat', 'table');

You will then need to access the data in the table (data.<columnName>) to apply strsplit() function. Refer to the following link on how to access data in a table:

If this doesn't work, share the values stored in the data table and we might be able to provide additional suggestions.

HTH!
