@Anonymous , Use any excel to json online convertor. Caution that the excel that is provided only has the above column. 

OR

Replace every ' by " and } by }, and in the same way introduce commas between every key-value pair. Paste all of the values in [ ]  in notepad and save it as .json .

Also that no two values have , between them, i.e. notificationID and unreachableCount are not differentiated.

@Anonymous Make a json where all of these are objects, then just uploading the data through json should do the work.
