If a cell contains the combined date and time, use a formula to extract the date or time in separate columns. Or, split the date and time without formulas use Excel's Flash Fill feature.
Split Date and Time ValuesIf you download data into Excel, one column might have a combined date and time value. In this short video, see how to quickly split that value into separate date and time columns. The first example uses a simple formula, and the second example is done without a formula  just a bit of typing. The written instructions are below the video. The Video Transcript is at the end of this page 
Get Date Value With FormulaIf a cell contains a combined date and time, you can extract just the date value, by using the INT function. Excel stores dates as numbers, with a decimal portion representing the time. In the screen shot below, there is a combined datetime in cell B2. In cell B3, the date has been formatted as a decimal number.
The INT function returns just the integer portion of that number, which represents the date. In the next example, the combined date/time is in cell A2. To get the date, enter the following formula in cell B2: =INT(A2) If the data is in a named Excel table, the formula will use structured references with the field names. In the example below, the combined date/time is in the DateTime column. Enter the following formula in the first row of the Date column (cell B2): Date: : =INT([@DateTime]) The formula should automatically fill down to the last row in the table. After you enter the formulas, format those columns with your preferred Date and Time formats. 
Get Time Value With FormulaIf a cell contains a combined date and time, you can use the INT function to pull the time value into a separate column. Dates are stored as numbers in Excel, with the decimal portion representing the time. There are 3 Time formulas below: 1. Time  Hour, Minute, Second 2. Time  Hour, Minute 3. Time  Hour 1. Time  Hour, Minute, SecondTo calculate the time value, subtract the date integer value from the combined date and time. The remaining decimal portion is the time. In the example below, the combined date/time is in cell A2.
To format the times,

Time Formula in Excel TableIf the data is in a named Excel table, the Time formula will use structured references with the field names. In the example below, the combined date/time is in the DateTime column. Enter the following formula in the first row of the Time column (cell C2): Time: =[@DateTime]INT([@DateTime]) The formula should automatically fill down to the last row in the table. After you enter the formulas, format those columns with your preferred Date and Time formats. 2. Time  Hour, MinuteIn some worksheets, you might want the time with hour and minute only, excluding the seconds. Use this formula in cell D2, where the Date is in cell A2
The TIME function has 3 arguments  1Hour, 2Minute, 3Second
To format the time for hour and minute:

3. Time  HourIf you just want to show the hour, you can show that value as a number, or as a time Hour as Number To get the hour as a number, use this formula: =HOUR(A2) Format that result as a Number or as General, to just see the number in the cell. Hour as Time To get the hour as time, use this formula: =TIME(HOUR(A2),0,0) Format that result as a Time, such as 13:30 or 1:30 PM

How to Split Date and Time in ExcelIf you have a file with dates and times in the same cell, we'll see two quick ways that you can separate that into date and time columns. Split With FormulasThe first one will use a formula. So in here I'm going to click and type an equal sign. We'll use the INT function, which is for an integer and that is going to pull the whole number from this cell, which is just the date part of the date and time. When I press Enter we'll see a date. Now if you see a number, you can format that as a date. Then I can select that cell, doubleclick on the Fill Handle, and I very quickly have all the dates. Get the Time ValueIf a date has a time attached to it, that's a decimal number. So if it's 12 noon, it would be the date number 0.5. So we want to just get that decimal portion, so we'll type equals the date. So that's the full member including the decimal. And then minus the date portion, we want to subtract that full number. So we'll use the INT bracket and click on the date. And when I press Enter, we get the time. And again, you might have to format that as time, if you're just seeing a number. And then fill that down. Split Without FormulasWe can also pull this out without a formula. So here's another copy of the same list. And in here I'm going to just type the first two dates. So I'll type 2/1/16 and 2/3/16. And now we're going to use the Flash Fill. And if you're doing this with text, it would fill down automatically, usually, once we set a pattern, but for numbers or dates, it doesn't do that. We can go to the Data tab, and click Flash Fill, and then it will suggest the rest of the dates for you. And then you can come here and accept or undo or just leave it as is if you want to accept it. Get the Time ValueAnd we can do the same thing for the time. So I'll type the first couple, and 9:32 And now again, I'll go and click Flash Fill, and it fills down the rest and they look fine to me. So I'll leave those as is. Now those won't change if these dates change. On the sheet where we used a formula, if we update a time or the date, because we have formulas here, those would update.
