I have this column in excel. The format is dd/mm/yyyy hh:mm:ss.SSS where SSS is milliseconds.
How can I make calculations such as subtracting two cells from each other? I keep getting an incorrect format error but I cannot find a format that includes date and time with milliseconds.
I am able to change the notation of the DateTime value but not split it into two cells.
Comments up above will suggest the built in test to columns method which works really well. Scotts tip about the third step is imperative. Jeroen's comments is using the DATEVALUE function which can be picky and somewhat dependent on your system settings. There is a third choice of using DATE. Jeroen's formula already does most of the work but needs a little tweaking. The nice part of DATE is it is not picky nor reliant on system settings.
Important tidbit of info. Excel stores dates as an integer with 1 representing 1900/01/01. Time is stored as a decimal which represents percentage of a day. So 0.5 is 12:00 noon. Also 24:00 is not a valid time for excel but will still work with some functions.
The DATE function looks for 3 arguments to be passed to it. Year, month, and day in that order. So it is just a matter of pulling the applicable parts of your timestamp as a string out and placing them in the right location. There is a Similar function for TIME.
Let assume one of your timestamps is located in C3
in D3 you can place the following formula to convert the date from text to an excel date:
=DATE(MID(C3,7,4),MID(C3,4,2),LEFT(C3,2))
In E3 you can place the following formula to convert the time from text to an excel time:
=TIME(MID(C3,12,2),MID(C3,15,2),MID(C4,18,6)
To get the information together its simply D3+E3. however if you want to place the whole formula in one cell and avoide helper columns, the formula would look like:
=DATE(MID(C3,7,4),MID(C3,4,2),LEFT(C3,2))+TIME(MID(C3,12,2),MID(C3,15,2),MID(C4,18,6)
Now that the time in in excel format you can perform operations on it, apply formatting to make it look like you want, and use various excel functions with it.

I am trying to link two Excel files and compare the values from first one in the second one, but I have a problem at some point.
So the date 28/07/2021 comes from the other file (which is call 3WLA). I had to use the function TEXT(..., "dd/mm/yyyy") otherwise it displays 44405 which is an other form of the date. Now I want to compare this date with other ones but it doesn't work as showed in the pictures below.
The picture shows the comparison of two dates coming from the other excel file 3WLA (still using the function TEXT(..., "dd/mm/yyyy")). We clearly see that there is a problem as it should display TRUE. In the same way, when I compare a date from 3WLA (i.e. using TEXT(..., "dd/mm/yyyy")) with a date random in my file it give me the following
where 28/07/2021 is given by = TEXT('[3WLA.xlsx]Block-First-Fix'!$AM$1,"dd/mm/yyyy") and 29/07/2021 by = 29/07/2021
chris neilsen already gave you the answer in the comments.
To clarify further: The text "29/07/2021" and the date formatted to look like "29/07/2021" are different data types. To help with this MS Excel automatically formats numbers and dates to be aligned to the right and normal text to be aligned to the left
In B1 you can see that the date has been formatted in the same way as per the formula in A2, but since the output in B2 is of the text data type, the two are not considered the same.
You can use the formula DATEVALUE to convert from text to date serial number. (Read more about date serial numbers here).
If your texts with dates are too different from your local settings date formats, DATEVALUE might not give you correct results. In that case use DATE function in combination with some text functions such as LEFT, MID, RIGHT
You can format the cell to make the date more readable using either the number formatting field or the dropdown from the ribbon
I have a combination of two reports into a master file. I'll be eventually transforming the data into a more readable format, but I have a date column that has two different types of date formats:
(yyyy-mm-dd & mm/dd/yyyy)
Is there a formula I can use to convert this so every cell reads: mm/dd/yyyy?
I know I can do it via text-to-columns, but that will take a bit longer than I'd like.
I will repost the question if it only can be done via VBA, but I figure there may be a way to just complete it via one formula and an auto fill.
You can probably just use:
=DATEVALUE(A1)
And copy it down. You can then format the date to whatever format you like.
DateValue() Takes a date stored as a string and converts to excel's date type.
I am simply importing CSV into Excel, In which I have a date column. it seem like this.
10.22.2014 13:34:00
When I am finish Importing Now I want to convet the whole date column to look like this in the format cell section but it is not working for me. Can you suggest another way. What can be the main reason SUppose i put a formula on the column then Everytime user import the data he need formula which might be not a good idea, Is there something I can do when I m importing or just like wondering what could be done?

Here's one approach:
Substitute dots with slashes
Use DATEVALUE, TIMEVALUE functions on relevant subsections of this substituted string. Subsections are fetched using LEFT and RIGHT string functions.
These return a serial number for dates (days since 1900) and time (a floating point between 0 and 1). When summed, the value can be represented as both date and time, in a format of your choice, as shown below:
Or, showing formulas:
EDIT: adding all-in-one formula.
Note that this will give you the serial value (41934.5652777778), which can then be formated using the built in formats for dates / times--just select the one you want. This does not actually render a string:
=DATEVALUE(LEFT(SUBSTITUTE(A1,".","/"),10))+TIMEVALUE(RIGHT(SUBSTITUTE(A1,".","/"),8))
If, however, you do want a string returned, you can use the TEXT function.
=TEXT(DATEVALUE(LEFT(SUBSTITUTE(A1,".","/"),10))+TIMEVALUE(RIGHT(SUBSTITUTE(A1,".","/"),8)),"m/d/yyyy h:mm AM/PM")
(This is done in libreoffice, but the same formulas and arguments exist in MS Excel)
I have some dated in this format "09-MAY-13 06.42.46.097127000 PM" and need to convert to this format "2013-05-09T18:42:47.132Z". my goal is to find out which happend earlier. I am not sure how to format these dates.

How I can do that??
I originally posted an answer which converted one of your formats to the other. I now see that you need to compare them, so you can convert this format in A2 to date/number values ....
09-MAY-13 06.42.46.097127000 PM
.....with this formula
=SUBSTITUTE(SUBSTITUTE(A2,".",":",1),".",":",1)+0
and this format in A3
2013-05-09T18:42:46.097z
....with this formula
=SUBSTITUTE(SUBSTITUTE(A3,"T"," "),"z","")+0
You can format the results how you like, leave as numbers or format as m/d/yyyy hh:mm:ss.000 or similar. you can now compare easily with a formula like
=B2>B3
or get the smaller or larger with MIN or MAX
If have a value of your original style in cell A1, place the following formula in a different cell:
=DATE((2000+MID(A1,8,2)),MATCH(MID(A1,4,3),{"JAN","FEB","MAR","APR","MAY","JUN","JUL","AUG","SEP","OCT","NOV","DEC"},0),LEFT(A1,2))+TIME(MID(A1,11,2)+IF(RIGHT(A1,2)="PM",12,0),MID(A1,14,2),MID(A1,17,12))
Then, in that target cell, apply the following format:
yyyy-mm-ddThh:mm:ssZ
Please note the following:
This assumes that all of your months are 3 characters (JAN, FEB, MAR). Since your example was "MAY" (already 3 characters), I don't know with certainty how your other months appear. Longer month names complicate the formula a bit. I can help with this if you need it and don't know how to do it.
I couldn't find a way to force Excel to display fractional seconds in the context of such complex date/time formatting, even though your example showed seconds subdivided to the thousandths. Hopefully this isn't a deal-breaker. If it's necessary to display fractional seconds, you may need to handle this with a separate formula to display the result as text, independent of the formula above, which you can use for your calculations of which date came earlier.
To add to Joe's answer...
To get Excel to compare one column to the other you need to do the same sort of manipulation from the first column as the second.
That would look like
=DATE(LEFT(A1,4),MID(A1,6,2),MID(A1,9,2))+TIME(MID(A1,12,2),MID(A1,15,2),MID(A1,18,5))
Once you have a new column for each of these transformations it should be simple to have Excel compare them.
I have 100.000 rows of data in Excel. Some of the fields are dates, but the fields in Excel are as text. I need these fields in number format including both dates AND time (e.g. 21.10.2011 13:10:50). Formatting the cells doesn't work because that doesn't change the datatype. I can pick out the date and time with formulas but not get them in the same cell.
So what I am looking for is the formula to calculate the number representation of a date (the one you see if you format a date as a number).
Have you tried the =DateValue() function?
To include time value, just add the functions together:
=DateValue(A1)+TimeValue(A1)
To accomodate both data scenarios you have, you will want to use this:
datevalue(text(a2,"mm/dd/yyyy"))
That will give you the date number representation for a cell that Excel has in date, or in text datatype.
I was struggling with this for some time and after some help on a post I was able to come up with this formula =(DATEVALUE(LEFT(XX,10)))+(TIMEVALUE(MID(XX,12,5))) where XX is the cell in reference.
I've come across many other forums with people asking the same thing and this, to me, seems to be the simplest answer. What this will do is return text that is copied in from this format 2014/11/20 11:53 EST and turn it in to a Date/Time format so it can be sorted oldest to newest. It works with short date/long date and if you want the time just format the cell to display time and it will show. Hope this helps anyone who goes searching around like I did.
The best solution is using DATE() function and extracting yy, mm, and dd from the string with RIGHT(), MID() and LEFT() functions, the final will be some DATE(LEFT(),MID(),RIGHT()), details here
