so you need to convert it to a t6 format, follow the steps:
1) Edit the script CSVtoHistory by giving to the String format the following value:
string Format = "+%Y.%m.%d %H:%M,f3,f1,f2,f4,f6";
2) save and run the script by clicking test
3) select the csv file
and then you are good to go, you will have an output of the same csv as a T6 file
