Excel公式计算签入时间

Question

I have a file from restaurant log of 1 month. I need to calculate the Checkin Time time from Time and Bill Number column.

My Format is:

Date |Time| TableNumber| Checkin time |Bill Number ..|...|...|  

I can calculate it manually one at a time by copying the 1st data of Time column and copying in Checkin time where bill number is same.

I have attached a Screenshot of the data.

Example 1: Blue square

Here in the blue square we can see that first value of Time column is 0:02:37 and I have pasted it in Checkin time which has Bill Number 29 .

Example 2: Red square

First value of Time is 16:08:40 And I have pasted in Checkin time column which have bill number of 1 and so on..

I did it manually without any equation or formulas. But the problem is the data is of 1 month and I have about 6 to be calculated.

What I tried From the formula given to me by @girlvsdata
I tried

 =MINIFS(B:B,E:E,E3) 

I did get the data for 1st two unique Bill numbers, but after dragging down the forumla further down, I get different Time for new bill number. + as the bill number repeats in further down rows many times, it gives me same time of 1st bill number for repeated bill numbers. Here is the screenshot of after What I tried Screenshot_after

Answer 1

If you have the latest version of Excel, you can use =MINIFS() to find the first Time for that particular Bill Number (the Checkin time ).

In cell D3 enter this formula:

=MINIFS(B:B,E:E,E3)

Make sure that the cell has Time formatting for it to show correctly.

Answer 2

So if i'm reading this correct you want to correspond the 'checkin time' with the first occurence of its bill number's 'time'?

You should use a formula in D2 like:

=INDEX($B$2:$B$1000,MATCH(TRUE,EXACT(E2,$E$2:$E$1000),0))

Confirm with Ctrl + Shift + Enter and drag down your formula

Note: Change $B$1000 and $E$1000 to whichever rownumber your sheets ends

EDIT 1

Here is an example of how this would work;

EDIT 2

Here is how it worked for me in your data:

Answer 3

I propose the following:

=IF(AND(E3=E1,C3=C1,A3=A1),D1,MIN(OFFSET(E3,0,-3,MATCH(0,(E3:E$18=E3)*(C3:C$18=C3)*(A3:A$18=A3),0)-1,1)))

It is a bit long and will likely take a while to calculate if you have lots of rows. The above formula is to be entered as an array formula, ie copy/type the formula then instead of pressing Enter, use Ctrl+Shift+Enter. If you do it right, excel will insert {} around it like in the screen shot below:

Change the ranges E3:E$18 , C3:C$18 and A3:A$18 accordingly and notice that they are all one row below the end of the table (otherwise you get #N/A for the last bill).
