I'd like to use array function to get conditional sum based on two columns. Given the example, for each ID I want to calculate the sum of value column if column B is -1
ID | B | value |
________________
A1 1 2
A2 1 3
A3 1 4
A3 -1 5
A3 -1 1
A2 1 5
A1 1 1
A2 -1 2
The outcome should be
ID | value_total |
__________________
A1 1 0
A2 1 2
A3 1 6
You want to sum
col C
for each unique value incol A
whencol B
is-1
? And you want a formula, not a macro? – Raystafarian – 2013-07-31T13:32:45.1771
You probably want a sumifs
– Raystafarian – 2013-07-31T13:39:24.900@Excellll What is the point in having "Microsoft-excel" and "Microsoft-excel-2010" both as tag? You can have all Excel questions in your favorite list with
*excel*
as tag. Note the placeholders – nixda – 2013-11-04T20:28:45.733@nixda See meta in a few places: http://meta.superuser.com/q/7105/76571 http://meta.superuser.com/q/1261/76571
– Excellll – 2013-11-04T21:53:23.593@Excellll Thank you, I already know them. In fact I thought a lot about them. I realized that there is confusion about this topic, so I try to convince others to remove redundant tags too. In this specific question, I may have chosen the wrong one since its more of a general Excel question. Please note that I would never remove e.g "debian" and let "linux" in place. This is only about Excel and its versions – nixda – 2013-11-04T22:04:11.577
@nixda ha I didn't look to see that your previous edit was to remove the general tag. I just happened to see it on the front page and I thought I'd fix it. Anyhow, I think the general tag is useful because it lets users of other versions know that the solutions here should apply to them as well. For instance I wouldn't want a novice Excel 2007 user to think
SUMIFS
was new to Excel 2010 and unavailable to them based on the tagging of the question. I suggest posting on Meta if you think Excel tagging should work a certain way. – Excellll – 2013-11-04T22:12:53.810
