I have a datetime string:
20221025133811 which is -> year month day hour minutes seconds
I want to paste it into an excel cell and make it a date-time object so that
I can subtract it from another date-time. I also want to keep it in the cell as 20221025133811.
I tried formatting the cell as 'Custom' and yyyymmddhhmmss but it doesn't work. How to do this?

Is there a way for me to format a column where the values I enter in the format HH:MM (elapsed time, not datetime) are converted to hours in decimal, preferably in the same column via some custom formula?
For example,
HH:MM
H (Decimal)
07:39
7.65
02:15
2.25
06:00
6
At the moment, I manually calculate the equivalent and enter them into the column but it would be nice to directly copy a timestamp and have the column automatically format it but I couldn't see an option for this in Date/Time formatting settings.
Simply multiply your hh:mm durations by 24, ensuring that the cells where you want the decimal hours returned are formatted as 'Number'. Or to force formatting as a number using a formula: =text(duration_cell*24,"#.##") where duration_cell is a cell with the duration in hh:mm format.
There is no way to do that I know of because Excel stores times/dates as floats. Each 24 hour period equals 1, therefore 7:33 equals .31458 Therefore, you won't be able to do this without a helper column.
You can do this with either #The God of Biscuits answer, or alternatively your helper column can have the formula:
=(A1*24)
and you set that column's cell format to Number.
All date and time is a format of a double value.
Time is the amount after the comma.
And all in front of comma is days since 00.01.1900.
Meaning 07:37:00 = 0,32 days.
Excel have a ways to pull the amount of hours with =HOUR('Your referance date time cell value')
You can aply this formula: =HORA(A2)+(MINUTO(A2)/60)
I have intial date time in this format
'2017-01-01 09:00:00.000'
I want to increment it by preferably by millisecond. Even second will do. I can't find formula for to increment Date time in particular format.
What I found was Time(hours,minutes,seconds) but it does not work.
Assuming your date is in Cell A1. The formula to add 1 second would be =A1+1/86400. To add a millisecond would be =A1+1/86400000. To add 5 milliseconds would be A1+5/86400000
I have got a start date and end date in this custom format
dd.mm.yyyy hh:mm in excel cells.
What i need is to fill specific row with dates incremented by half hour from start date to end date using VBA code. And i havent got any idea how to do this.
On web there are some examples with similar problems but with only months or only hours and those are dates format not custom.
You can do this with a simple formula.
Write your start date into cell A1
In A2 write =A1+(1/48)
Copy formula from A2 down
done.
How does this work?
Excel dates are represented as count of days since 1900. That means 1900-01-01 is the first day and represented by 1. All other dates are just the count of days since then. 1 represents one day. So since 1 day has 24 hours 1/48 represents half an hour.
The number format dd.mm.yyyy hh:mm how Excel shows the date is not relevant, because Excel only saves the value (amount of days since 1900) in the cell value.
So if you type the date of today into a cell 2018-10-11 Excel actually saves 43384 in the cell value (today it is 43384ᵗʰ day since 1900-01-01).
One option is to find the interval between start and stop point. Remember that excel dates that are actually dates and not strings are actually integers. The second thing to remember is time is the decimal part which represent fraction of a day. Test if your date (assuming it's in A1) is an actual date or a string with
=ISNUMBER(A1)
If that comes back TRUE you do not need to worry about converting your date. If it comes back FALSE, its actually a string and will need to be converted for excel to work with it.
Divide this interval by 30 minutes, or 30/60/24 to and add 1. This will tell you how many iteration you will need which you can put into a For loop
Start_Number = Range("A1")
End_number = Range(("A2")
Stamp = Start_Number
Interval_number = End_Number - Start_Number
Counter = integer of (Interval_number / (30/60/24))
For x = 1 to counter
write Stamp to cell
Stamp = Stamp + 30/60/24
Next x
Allternatively you could set up a while loop.
Do While datetime < Stop_Point
Write datetime to cell
Datetime=datetime + 30/60/24
Loop
Please note, not actual code but giving idea where OP had no idea where to start.
Is there any option to compare dates with Date format yyyymmddhhmmss with the current date?
Basically one of my external source have this type of date and I have to compare this date with the current date and check difference in between. I have tried to split those date with LEFT,MID,RIGHT functions, so basically, I have two columns - first with date, second with time, but I cannot find any option to subtract current date with date in column, because results are not coming correct.
Sample of date: 20161112203545
after splitting: 2016-11-12 20:05:45.
Any ideas?
Image produced below with formulas is self explanatory.
Your date :20161112203545 in D4
Formula to convert date in E4 :
=DATE(LEFT(D4,4),MID(D4,5,2),MID(D4,7,2))+TIME(MID(D4,9,2),MID(D4,11,2),RIGHT(D4,2))
Today's Date in F4 : =TODAY()
Formula to get date difference in days in G4 : =DATEDIF(F4,E4,"d")
EDIT
The alternative to Excel DATEDIF would be a User defined function (UDF) that internally uses the VBA DATEDIFF function:
This UDF accepts three parameters:
Start_Date: The days from which the period begins.
End_Date: It is the last date of the period that you wish to calculate.
Unit: It specifies the interval by which you want the difference. Here the unit accepts following values.
Value Description
YYYY Year
Q Quarter
M Month
Y Day of year
D Day
Public Function xlDATEDIF(Start_Date As Date, End_Date As Date, Unit As String) As String
xlDATEDIF = DateDiff(Unit, Start_Date, End_Date)
End Function
In this case usage will be, put formula in H4 =xlDATEDIF(F4,E4,"D")
HTH
Taking the date as
20161112203545 after splitting: 2016-11-12 20:05:45
Is going to cause you some issues as Excel assigns date values with a serial number, and it's going to throw that number off. You could use the =today() function and set it up where you have the date entered, say it is in cell A1, then =A1-today() (formatted as a number) should give you the difference in the amount of days.

I have a date in text form that excel is not recognizing as a date and hour like i want it to. Is there a formula to break down this text and then build it back up as the correct date and time?
01.01.2012 08:00:00.000
=DATE(MID(C5,7,4),MID(C5,4,2),LEFT(C5,2)) + TIME(MID(C5,12,2),MID(C5,15,2),MID(C5,18,2))
When the date string is in cell C5
