I get a text report from our time keeping system that i dump into excel through a data connection and I need to calculate the total hours for a day, the problem is, some employees clock in and out for lunch, so there could be up to 4 punches per day per employee. I am trying to automate it so that it will subtract the clockin time from the lunch clock out time, and the lunch clock in from the end of the day clockout to give me total hours worked for the day. Example, if I have these 4 times:
7.82
12.60
13.02
16.66
I need to subtract 7.82 from 12.60 and 13.02 from 16.62, and then add the two numbers together for the total for the day. I have no problem doing this if everyone clocked 4 punches a day, but some clock 2 times, and others 4, just depends on whether they leave for lunch. I get the data with a date and time stamp, is there a way to do this either with vba or a formula? I need excel to recognize whether there are 2 or 4 punches so it will know what to subtract from what? Any help is greatly appreciated! Here is an example of what the data looks like:

I convert it 100 minute time also.

Sorry, hit post before i was ready! There is quite a bit of vba that refreshes the adminreport-utf8 tab, then moves all the data to the corresponding tabs. Columns A B and C get cleared each time, but Column D (where your formula is remains untouched. Also, I tried adding your formula as an if statement, saying if A1 is blank, then blank, else your formula, but couldnt get it to work.

My functions require that there's an unused row 1 for it to work. That's why I put headings on my data example, and my formulae must start in row 2.

If you can change your VBA to leave row 1 empty and start populating from row 2 it should work.

I see you have a maximum of 30 rows per person so all the $16 in my formula should be changed to $30


Would you like me to take your adminreport-utf8 table and provide the calculation in some unused columns there?

Awesome! I get it now! I will change my vba to start everything on row 2, and I will change the 16 to 30. Do I still need to put the formula in row 1, or start it in row 2?

Start the formulae in row 2
That works great! Any thoughts on the "if" part? I need for the cell to stay blank if there is nothing in column A, but when I put the if statement in, it doesnt work, here is what I am trying:
=if(a2="",'"",CHOOSE(COUNTIFS($A$1:$A2,A2,$B$1:$B2,B2),"",24*(C2-INDEX($C$2:$C$16,AGGREGATE(15,6,ROW($C$2:$C$16)-ROW($C$1)/(($A$2:$A$16=A2)*($B$2:$B$16=B2)),1))),"",24*(C2-INDEX($C$2:$C$16,AGGREGATE(15,6,ROW($C$2:$C$16)-ROW($C$1)/(($A$2:$A$16=A2)*($B$2:$B$16=B2)),3))))

Looks like you picked up a single apostrophe in your double-quotes.

Hey! I was wondering if you could help me one more time with your formula? It works great for the people who clock in and out on the same day, the problem is, we have people who work nights that clock in before midnight on one day, and clock out after midnight, so that puts them on the following day, and it doesnt calculate them due to the diff in the dates? Example below. TIA
