Sum duplicate values then delete duplicate rows

This is a formula I use occasionally for something like this. (Each book title will need to be spelled exactly the same for this to work.)

First, sort list by book title then apply the formulas as shown in the example. (A list of 20,000 using this formula can take a little time to complete all calculations depending upon your PC configuration.) When it is complete, copy column D and paste special as values. (highlight column D, right click on it, select copy, right click again on column D and select paste special -as values) This converts the formulas to values. Now set a filter on column D and select blanks. Highlight all of the rows remaining and delete them. (You may want to first re-sort your list by column D before setting your filter and deleting so that all blanks in column D are together. Sometimes deleting rows non-adjacent rows on a large list will cause delays and sometimes you will get an error message. After you delete rows, you can re-sort your list.) Release filter and what you have left is the completed list showing one title per book and total number of times all copies have been checked out.

Hope this helps.

Thank you so much for replying but I'm having trouble getting the answer that you got.

i clicked on the empty cell in column D (#2) and pasted your formula...got 114.

I tried highlighting the entire column of D and pasting the formula but excel says it's a "circular reference".

I know this sounds silly. But could please explain step by step how to you did it? Did you highlight everything and then put in the formula? Do i copy the formula word for word? The first file that I am going through has only 3,176 titles. Should that number be someone in the formula you provided?


I really appreciate your help. I am totally a newbie with using formulas in excel.

i clicked on the empty cell in column D (#2) and pasted your formula...got 114.

Click to expand...

Are you saying 114 is not the correct result for D2? Based on the info you provided, I believe it should be. Did you sort your data first?

If you are saying 114 is correct for that cell but the problem you are talking about is filling in the formula for the rest of the column, then follow these instructions.

After pasting the formula in D2 and hitting enter, run your mouse over the lower right hand corner of the cell. (You will see a very small square in that corner.) When you run your mouse over this square, the cursor will change from a fat plus sign to a skinny plus sign. When you see the skinny plus sign, left click on it and hold while dragging down the page to the last row of data. This will copy your formula down the page. You can also just double click on the little square instead of dragging but in this case you have to make sure something is in all cells in C or that operation will stop at the first blank cell in column C.

The circular reference error comes from a formula in a cell that is referencing that cell so somehow pasting the formula into the entire column caused the formula to get out of sequence from the way it was original intended.

By the way, the dollar signs in the formula lock down that reference so that when copied that row and or column doesn't change. For example....A1 has 4 possibilities. A1, $A1, A$1, $A$1. A1 would change when either copying the formula down or across the page. $A$1 would not change if copying either down or across the page. $A1 would change when copying down the page but would not change when copying across the page. A$1 would not change when copying down the page but would change when copying across the page. The easiest way to learn this is to replace the $ with the word "Always". $A$1 would be Always Column A - Always Row 1 and so forth. I probably didn't do a very good job of explaining this as I am in a hurry but if you search for relative and absolute references on this site, you can probably find some very good explanations. Understanding this concept is important when trying to duplicate formulas.

When you get this to work, make sure to follow the original instructions of copying the formulas and pasting as values before you delete them. Otherwise your totals won't be accurate you'll have some errors in the formulas.

Good Luck

Hi,

A perfect job for pivot table.

Have a look at here

HTH

gnrboyd,

Thank you so much. I sent you a private message just a little while ago saying that i got it. So thank you, thank you, thank you!

I actually figured it out after toying with the formula for a while. I ended up pasting the formula in D1. It gave me 114 the correct answer. I then just copied that cell and pasted into the rest of the cells down to the last one. When I hit "paste" the formula worked for all of the titles...took only a few seconds for my first file, containing only 3,176 titles.

SO THANK YOU, THANK YOU, THANK YOU!!

Irina

Krishnakumar,

thanks for the reply!!
