Using COUNTIFS with multiple columns
I have a large sheet of 800,00 rows and about 50 columns.
Some of these rows have the same values in certain cells as other rows. I want to be able to identify the duplicates by certain columns.
ie, if the data in column A, D, F and R is the same as another row, it should be marked as a duplicate.
I hope this makes sense. I can find duplicates in one column by using a countif and then counts of 2 or more are duplicates. But I don't know how to bring in other columns to the calculations, can I use 2 countifs in the same calc?
I have attached an excel sheet with two questions to set up a countifs formula for multiple conditions. I have tried to explain it fully in the attachment if anyone would be kind enough to look at it.
I'd like to use multiple if countifs, I tried a couple of formulas and even though the formulas work I keep getting the wrong results.
I've tried the following:
What's the problem with the above?
I am wondering how to use an IF function nested within a COUNTIFS function, or if this is even possible. Specifically, I have three columns of data - Team, Points For, Points Against. Then, each row represents a "game". So team "XYZ" will have multiple rows of data.
I am trying to consolidate the info into a new sheet with again three columns, but this time they are as follows: Team, Wins, Losses. However, there would only be one row per team.
Can I use COUNTIFS to return the number of times a given Team's "Points For" value is greater than its "Points Against" value, thus giving me total number of wins?
All I can think to do is somehow nest an IF function within the COUNTIFS function (which I have been unable to figure out so far), but maybe I am just way off in the first place.
Can the countifs function be used to count cells across multiple worksheets? I keep getting a #VALUE! error. I have tried changing the format of the cells in question but I cannot resolve the error.
