Convert time to Half Hour inverval

[BenS]

I have a list of date/time values which I plan to use text-to columns to
strip away the time.

Next, I need to convert these time values into half hour interval values but
don't know how to do this.

For example
Original Value Converted Value
23:16 23:00
09:56 09:30

So, you can see I'm converting the time to the last half hour that passed.
Can anyone suggest a formula or method to simplify this for me? Many thanks
in advance for any assistance.

=TIME(HOUR(A2),IF(MINUTE(A2)<30,0,30),0)

Note that this will also strip away date values as well.

HTH,

saved me a great deal of time and effort. Have a fantastic day!
