In Excel, if you have in a cell with date and time (like the use of the NOW function) it's easy to split them with 2 formulas.
Your cells have Date and Time
Let's start from the following document where you have in column A Date & Time

We want to split
- The date in column B
- And the time in column C
To perform this separation, we must keep in mind that 1 represents 1 day.
Time is a fraction of a day, for example, 0.33333 is 8 hours (1/3 of a day). Have a look at this article about the Date and Time format.
Step 1: Extract only the date
So, to extract the date, you just have to insert your value in column A in the INT function.
=INT(A2)



INT means integer, so you extract the whole part of the cell in column A. And the whole number is the date (the decimal part is the time).
It is possible that you need to change the format of column B to display the format 'Date'.
Step 2: Extract the time
To extract the time, simply subtract the data in column A with the entire value calculated in column B.
=A2-B2



Again, it is possible that you have to change the format of column C to display the cell format to 'Time'
And the final result is
