How do i use a lookup in excel to return a value from a third column, if criteria are met in 2 other columns

Question

I have a dataset which has columns as follows. It shows me the number of people (in the time columns) that are in the room (resource) on date.

Sample Dataset:

I am attempting to return the following.

Sample Result:

Essentially, im trying to search my dataset, and return the number of people in each room, at each time and date, in a more digestible manner.

Apologies if i havent explained myself correctly, and i havent really worked out how to use this forum properly yet, but i'm hoping to use the collective to help with this problem. I'm not an excel newbie, but i can't seem to get the right mix of match/index/v/hlookups to do what i need! Thanks :)

Ok, so updating based on NightCrawler's assistance, still getting random errors at 1 and 4pm! any tips?

Answer 1

I achieved your desired result using this formula. I added another column to get correct dates in each row because i did not want to deal with merged cells (see image).

=SUMIFS(OFFSET($C$2:$C$7,0,MATCH($D11,$C$1:$L$1,0)-1),$A$2:$A$7,$B11,$B$2:$B$7,E$10)

Drag the formula to all cells

Answer 2

Here is another method you could use

Select your data. Goto Data Tab. Under Get & Transform, click From Table. In the pop-up check My Table has headers -> OK

A window(Query Editor) will pop-up.

Select your time columns and in the transform tab click Unpivot Columns. This is what you will get

Notice that the time column is now renamed and there is a new colunm "value".Now select your resource column and click on Pivot column (Transform tab). For Values Column, choose Value(the new column that was added) . In advanced options, make sure "Sum" is selected.

Click OK . you should have your result. In the Home tab click close and Load.

The rows may not be in the correct order, coz you are using it as a string. You may use numbers for better sorting.
