the columes are already seperated, just a bit hard to see, I am using a
program which returns time values into excel as an array where the length of
column values varies dependend upon operating houors, it also pastes a "1" at
random intervals in the next column, where there is a "1", I want to find
each occurnace and return the value in column 2, hoever need to do this using
an array formula so I end up with this at column 4


4:05
0:16
0:04

i.e no spaces.

cheers

It's unclear whether the date and time is contained in one column or
two. Therefore, try the following...

If Column A contains the date, Column B contains the time, and Column C
contains 1:

D1:

=IF(C1=1,B1,"")

D2, copied down:

=IF(C2=1,B2-B1,"")

If Column A contains both the date and time, and Column B contains 1:

C1:

=IF(B1=1,A1-INT(A1),"")

C2, copied down:

=IF(B2=1,(A2-INT(A2))-(A1-INT(A1)),"")

Hope this helps!

when the number 1 is found return, 4:05,0:16 etc, but have these grouped
togther at the top of the column, as I have a varing array of numbers,
