    Different date formats in same source

    Hey, glad to be back here!

    I am automating some worksheets so that I can hand them over to someone else without them having to do (ideally any) manual effort. The file handles timesheet entries (people log the hours they work) and from there I run a pivot table that shows me hours worked per week/month/project etc

    The source of my spreadsheet is a time & date field, coming from an external system. The values are exported in 2 US formats:

    02/14/2019 07:15 AM - so mm/dd/yyy hh:mm AM
    or
    02/06/2019 08:32 - so mm/dd/yyy hh:mm

    Using my manual solution I use the text to column to get these entries into a manageble dd/mm/yyyy format which Excel recognises. However, I want to avoid doing this type of manual manipulation if I can help it, so I just want to do this using formulas.

    How would you do this? My attempts using TEXT, LEFT, WEEKDAY have not worked just yet.

    Thanks for your reply Ace_XL. Unfortunately this doesn't do the trick in the first format.
    Find very small file attached. How can I get to WEEKDAY in column C?

    Odd, the file you attached gives me correct anticipated results.

    If you're looking for WEEKDAY, simply reference the data source i.e. Col. A of your sample rather than Col. B

    =WEEKDAY(A2)

    Does that work for you>

    Your second value is text in your example, you may need to change the , to ; in your locale


    =IF(ISNUMBER(A3),INT(A3),DATEVALUE(LEFT(A3,10)))

    Thanks davsth. This doesn't work for me either on the second value. If I do text->columns to strip off the AM it does work but want to avoid that.

    Re: Different date formats in same source

    which is why you apply it to the above in #5

    or

    =weekday(IF(ISNUMBER(A3),INT(A3),DATEVALUE(LEFT(A3,10))) )

    Re: Different date formats in same source

    IF(ISNUMBER(A3),INT(A3),DATE(mid(a3, 7,4),LEFT(A3,2),mid(a3,4,2)))

    any better?

    Perhaps the locale is the issue. Whatever I do, row 3 gives me errors on every formula. See attached:

    PS really appreciating you taking the time to help out!

    Re: Different date formats in same source

    Nearly there... the formula is nearly perfect.

    Remaining problem is that when ISNUMBER is TRUE, the month and day are switched so something goes wrong with the INT function.

    In the attached you see how the date shown is 11-Jun but in fact it should be 6 November.

    Re: Different date formats in same source

    Try this amended version of davsth's formula

    =IF(ISNUMBER(A2),DATE(YEAR(A2),DAY(A2),MONTH(A2)),DATE(MID(A2, 7,4),LEFT(A2,2),MID(A2,4,2)))

    Re: Different date formats in same source

    Hi Deemo, if you look at the formatting of those first 2 cells, they are NOT in USA format, they are formatted as d/mm/yyyy h:mm

    That did the trick, thank you.
