回答1:
"no the data is downloaded not imported" <--- what they mean is.. when you have the original downloaded data.. don't format it as "Date". Leave it as is it.. ("General"). Then use 5 extra columns to check the date and time.. put in these formulas and drag it downwards.
column 1 --> =month(A87)
column 2 --> =day(A87)
column 3 --> =year(A87)
column 4 --> =hour(A87)
column 5 --> =minute(A87)
From the pattern , you should see a pattern if the month/day was formatted wrongly. If it is.. just use one more extra column to combine the "correct" date & time by using =date(...)+time(...) .
Have a try and share if these works or not. We can proceed from there.
Hope this helps. ( :
