Convert Date String To Date Time Excel Formula

To extract the time, the formula in D5 is: To assemble a datetime, the formula in E5 is:

Date

To get the date, we extract the first 10 characters of the value with the LEFT function: The result is text, so to get Excel to interpret as a date, we wrap LEFT in DATEVALUE, which converts the text into a proper Excel date.

Time

To get the time, we extract 8 characters from the middle of the text with the MID function: Again, the result is text. To get Excel to interpret this value as time, we wrap MID in TIMEVALUE, which converts the text into a proper Excel time.

Datetime

To get a final datetime, we just add the date value to the time value. The formula in E5 is: Once you have a valid datetime, use custom number formatting to display the value as desired.

All in one formula

Although this example extracts the date and time separately for clarity, you can combine formulas if you like. The following formula extracts the date and time, and adds them together in one step: Note that DATEVALUE and TIMEVALUE aren’t necessary in this case because the math operation (+) causes Excel to automatically coerce the text values to numbers.
