I have data for start and end times on specific dates. The data in start
date/time is formatted as 10/01/2006 7:30, and in end date/time as 10/01/2006
15:30. When importing the data from another application into Excel, I only
want data returned from 7:30 to 15:30, but the application isn't doing that.
For example, it's pulling data such as 10/01/2006 16:00 for start time and
10/01/2006 18:00 for end time. Is there an IF statement (or other statement)
I can write in these cells to include only cases that start at and between
7:30 AM and end at and between 15:30 (3:30 PM)?

Just select the date/time combinations, right click, format cells and format
as time. The date will be stripped out.

XL stores time as fractions of a 24 hour day. 7.5 is the numerical
equivalent of 7:30 AM (i.e., 7.5 hours of the 24 hour day have elapsed).
15.5 is the numerical equivalent of 3:30 PM.

The square brackets are an indication that you need to put the appropriate
cell reference there. Eliminate the square brackets and re run your formula.

There are a number of reasons why that won't work:

1 If you want to include only times between 7:30 and 15:30 you need AND,
not OR
2 Your OR function has opened the parentheses for this list of arguments,
but closes them after the first argument. You need to delete the
parentheses either side of that next comma.
3 The formatting to time doesn't change the value, so the date part is
still in there.

I took out the square brackets and ran the formula as you wrote it, but Excel
now says I've entered too many arguments. Suggestions please?

Ah, you've just fallen victim to one of the oldest traps in computing. If
you look at the =MOD(A2,1)*24 term, with enough decimal places visible,
you'll see that it says 15.5000000000582, rather than 15.5. This is because
the original time is stored as a fraction of a day, and 15.5/24 is
0.6458333333333...
The latter number can neither be expressed exactly in decimals, nor in
binary. When you've got a binary approximation to that and multiply it back
by 24, it doesn't come quite back to the number you first thought of.
It is always dangerous looking for exact equality in a computer's
representation of a loating point number. Integers are OK, but for
non-integer you'll run into problems with anything other than 0.5, 0.25,
0.125, etc. and multiples thereof.

in
start
date/time is formatted as 10/01/2006 7:30, and in end date/time as
10/01/2006
15:30. When importing the data from another application into
Excel,
I only
want data returned from 7:30 to 15:30, but the application isn't
doing that.
For example, it's pulling data such as 10/01/2006 16:00 for start
time and
10/01/2006 18:00 for end time. Is there an IF statement (or other
statement)
I can write in these cells to include only cases that start at and
between
7:30 AM and end at and between 15:30 (3:30 PM)?

maybe precisely
=IF(AND(round(MOD(A1,1)*24,2)7.5,round(MOD(A1,1)* 24,2)<=15.5),"Include","Exclude")...a modified integer version

There are a number of reasons why that won't work:

1 If you want to include only times between 7:30 and 15:30 you need AND,
not OR
2 Your OR function has opened the parentheses for this list of arguments,
but closes them after the first argument. You need to delete the
parentheses either side of that next comma.
3 The formatting to time doesn't change the value, so the date part is
still in there.

Try
=IF(AND(MOD(A1,1)*247.5,MOD(A1,1)*24<=15.5),"Incl ude","Exclude")

XL stores time as fractions of a 24 hour day. 7.5 is the numerical
equivalent of 7:30 AM (i.e., 7.5 hours of the 24 hour day have elapsed).
15.5 is the numerical equivalent of 3:30 PM.

Just select the date/time combinations, right click, format cells and

I thought David explained rather well the problems with decimal
representations of binary numbers.

The conversion could be avoided if the formula used were
=IF(AND(A1Time(7,30,0),A1<=TIME(15,30,0),"Include ","Exclude")

Ah, you've just fallen victim to one of the oldest traps in
computing. If
you look at the =MOD(A2,1)*24 term, with enough decimal places
visible,
you'll see that it says 15.5000000000582, rather than 15.5. This is
because
the original time is stored as a fraction of a day, and 15.5/24 is
0.6458333333333...
The latter number can neither be expressed exactly in decimals, nor
in
binary. When you've got a binary approximation to that and multiply
it back
by 24, it doesn't come quite back to the number you first thought of.
It is always dangerous looking for exact equality in a computer's
representation of a loating point number. Integers are OK, but for
non-integer you'll run into problems with anything other than 0.5,
0.25,
0.125, etc. and multiples thereof.
