Excel Magic Trick 473: Extract Unique Records with Formula (Complex Array Formula)

So I used Excel Magic Trick 185 to dynamically pull content from a spreadsheet: http://www.youtube.com/watch?v=6bGKhbUYOas

However,
It is only working for a few of my columns though and I am getting reference errors, http://www.mediafire.com/?gje8srbp8x2j48w

Can anyone check into my spreadsheet and help me understand why I get these ref errors? Is it because I have spaces in the column names or within the cells? I know a macro is probably a better way to do this, or an auto-filter, but I need it to dynamically update. Any ideas on how to fix this problem or a better way to solve it?

Thanks!

Hello There,

I have another question for you all. What I am trying to do it extract unique data from a list that I have. I know that I can do this through filters but this is not what I want. What I have is a list that looks like this

shoes
shoes
shoes
shirt
shirt
shoes
shirt
pants
shirt
pants
hats

now what I am wondering with out using a macro or a filter if there is a way to use a formula to extract the unique data and end up with a list like this

shoes
shirt
pants
hats

Any help would be greatly appreciated.

Thanks

I am following this tutorial from youtube. It is a search function to search for a specefic word in an entire row. Here is the first part of the code:

Code:

=SEARCH(C$3,Table2[[#This Row],[DESCRIPTION]])

except i only get a value in the cell that i typed this in, instead of it searching the rest of the row like in the tutorial. i can't figure out how to fix this. anyone know what im doing wrong?

Good morning,

trying to find out what to do with my spreadsheet and the formulas in it.

If you look into the file 369. I can get to the stage where it outlines the mismatch figure. In the example it is 6 Mismatches.

But I cannot seem to get the table belwo right. Everytime I try and copy past the formula, the first set of data is the one from the first line and then I get a #NUM error, due to the fact that there seems to be a number reoccurence somewhere.

I took the youtube tutorial, but even copying that formula did not work.

My table consist of 2 sets of 600 values each.

Can someone tell me why I am getting this error and help me resolve the issue that the result is an existing set of data?

THANK YOU

Hello there.
First, and before all, I must admit that I am a kind a "dumb" for Excel, because I always were using it, only for better look's of simple tables, schedule's and similar. Although, I was all the time aware of great power's of this program, but newer tested it.
So, finally after few years of tempting, I decided to make a proper "order-list" for the shop in which I work. What I needed is to ,based on products and their prices, make a drop-down box, with list of the products, and after choosing one , proper price will be shown in next column. I find out how to do it with "Excel magic trick #5" on Youtube.
This is what i achieved:

However,
You see that in row 16, or line 2 in the order box ,we have #N/A below Cena (Price), Iznos PDV (amount of VAT), Cena sa PDV (Amount with VAT), and Iznos (Total amount). If we choose one of the product from drop-down box (now, as You can see none is chosen) and type number in Kolicina(Quantity) column, all this would be automatically changed into proper value.
But what if we have only one thing in order box, instead of 2 or all of 10 ? How to avoid those #N/A, and make instead to be blank cell, which is to be counted as 0, because of final calculation?

In this order-form we have only line 1 and 2 programed to have drop-down box in line Naziv robe (Name of the product). If I putted same drop-down boxes in rest 8 columns, #N/A would be shown in all programed cells bellow, like in line 2...

Kind regards from Serbia

Hello,

I am constructing a make-shift database in excel but can't seem to find a way to get magic trick #213 to work.

What I am trying to do is create a dynamic filter via 16 criteria. I would like any results that match all criteria that I specify and then displays results in a separate table to the right.

Thank you so much for your help - I would attach my spreadsheet to this message if I knew how.

Looking for a little help tweaking Excel Magic Trick 185. I've reached what is probably just a mental block.

I'm trying to adjust a spreadsheet for work using the processes described in Excel MagicTrick 185. (Great series, by the way...) The catch is that the source data table can not be modified under any circumstances (we've already asked).

The problem is different than EMT_185 in that there are 9 columns that can potentially define a match as opposed to just the one shown in EMT_185. There are two user options ('I-III' and 'A-C') which in combination establish the headings for the 9 possible conditions (I-A, II-A, III-A ...) .

(See the linked spreadsheet) I've been able to:
determine if a row in the source matches user provided conditions (col Y),
get the count of matched source rows (row 26),
determine the match instance (col AA), and
place the source data in the output table (col AC)

What I can't quite get my mind around is suppressing the blanks in the output (i.e.:getting match 1 on row 1, match 2 on row 2, etc.)

What am I missing? Please help. A spreadsheet showing what I have so far is located on google docs. Perhaps you could make a new EMT out of it!

BTW.. this used to be done via vba, however that is no longer an option (don't ask... It just isn't, and it's not a topic that is open to discussion -- we tried).

I am trying to duplicate the concept on my spreadsheet. It is conceptually the same, the formula is slightly different.

Mine is as follows:
{=IF(ROWS(A$5:A5)>$B$2,"",
INDEX(US!A$5:A$72,
SMALL(IF(US!$AU$5:$AU$72=Sheet1!$A$2,ROW(US!$AU$5:$AU$72)-ROW(US!$AU$5)+1),ROWS(A$5:A5))))}

Resulting in a #VALUE! error. Can anybody advise me what should the formula me?

Thank a million!

Hi

I have a column A1 to A750 with many duplicated values. I need a formula to extract the unique values from this column to an array. I want to use the array to act as a data validation list.

I would like to avoid using advanced filtering if possible.

Any help would be much appreciated.

Hi, back again asking for help. I need to lean a worksheet of all array formulas and I don't know how to "translate" this one.

Code:

{PRODUCT(alfa+a1:z1)}

where alfa is a cell. This formula appears everywhere and alfa is always different so I cannot simply create a row with the argument of the PRODUCT formula for I would have to create a lot of rows. Of course the array formula works beautifully but as I said I need to remove them all (if it is manageble)

Is there any trick which would do the job ?

thanks a lot for any suggestion

Paolo
