I have a big datatable from Excel that i want to sort into smaler datatables by month. but the date are all in format “dd/MM/yy”, how do i take this big datatable and put in in different tables by month when the colum date is “dd/MM/yy” ?
using this code we can sort .
(From p In dtDummy Order By DateTime.ParseExact(p.Item("datestring").ToString, "dd/MM/yy", System.Globalization.CultureInfo.InvariantCulture) Ascending Select p).CopyToDataTable
Refer this xaml file for sorting the date string from datatable.

Do you want to split each month in a different datatable from the main datatable???
Year wise also???

almost, i can’t post example program because i’m New to the forum, so i have to try to explain better.
i have example 100rows and 20 coulums in my DT.
the 100 rows is for one hole year.
i want to split these 100 rows into 12 DT’s by wich month it is and then put it back in 12 different Excel files.
one file each month With all the 20 coulums.
Yes you can get the 12 different datatable based on your input, only one thing you need to do you need write it into the excel file using write range activity.
Like the same thing . i need to sort the table based on dates . I am reading data from excel which contains the date and am using your for sorting but unfortunately am getting error stating that “string is not a valid date” . I am not sure whether my approach is right, can u help me out with this problem?

After sorting the dates in descending my output should get the nearest date (ie) 20/03/2018
Try below code.
(From p In dataTable Order By DateTime.ParseExact(p.Item("Date").ToString.SubString(0,10), "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture) Descending Select p).CopyToDataTable
@arivu96 Thanks for the reply. The code works well. but i need get the future most date (ie). 20/03/2018
but this codes sorts in the following order

Thanks @arivu96 its working fine ! but can you clarify me why have u added that subString(0,10)?
dd/MM/YYYY has a total length 10 so starting from 0 taking 10 characters. Hence subString(0,10)
