Hello @balaji_yadav
convert the first row to date time datatype so that you can add 10 minutes to it than compare it with dates in the sheet than use if conditions to compare for all the three conditions
take a look at this workflow for better understanding Temper.xaml (16.7 KB) tempera.xlsx (9.1 KB)
You will get the value as row(“Date and Time”).Tostring and it is of type string,
Before If condition, assign the value to a variable of type DateTime and convert the value you got above as DateTime.Parse(variable you assigned value of row)
Use assign activity in THEN and get the index of that row as mentioned above and assign it to a variable
Again within THEN, use excel application scope, and set Range color activity in the body
