Search In Large Array For Value
Jun 20, 2007
Hi again, I am trying to find the easiest way to repeatedly search a large matrix (300,400) for a particular value. I have used two for loops in the past but its starting to get complicated now. Is there a workaround using application.worksheets.something that I could get a true of false reply? Someone may suggest that I create a function that replys back. I am new to VB and I am not sure how to send a matrix of integers to a function (syntax).

I'm having a difficulty using LARGE and SMALL.I want to return the 1st to 5th value of an array (each in a different row) choosing months as criteria. While the LARGE formula works fine, when I replace the LARGE() formula for the SMALL() leaving everything else unchanged, the formula returns ZERO and there are no ZEROS in the original data! Here is the function:

Column C contains the names of real-estate brokers.
Column E contains the colors of the homes for sale.
Column Q contains the values of the homes.
I want to return the sum of the 50 most expensive homes that are yellow and for sale by Century 21.
I'm familiar with array formulas, and with the large function. I just do not know how to incorporate the large function within the sum/array formula.

My problem is that whilst dealing with large datasets, i'd like to be able to create a macro which will give me a pop up box to input different types of keys words to search within a dataset. Once these keys words have been found, i would like excel to highlight the entire line so it can be extracted into a new worksheet.

I have some product SKU's in Exel all in the same column and all unique. The problem is I have been building a product database for my website and only just noticed that the CSV file my distribution company supplied me with didn't include the product description. Since then the distribution company has added a description field to the feed, however the company has added products within this time so it's not as if I can copy and paste the description field into my product database as the wrong descriptions will match with the wrong products. Is there any way I can highlight all of my sku's and the rows they are in? This would work a treat as I could just select all of my SKU's in my product database and then find those products only in the CSV file the company has supplied me with.

I am trying to calculate a matrix of array formulas that is roughly 365 x 137, or about 50,000 cells being calculated from a range of roughly 12,000 x 137. There are multiple if statements within the array formula, and then those 50,000 cells are referenced to another, but smaller matrix of array formulas (25 x 137). Each of these matrix sets is for one year, and there are three years that need calculated.
Problem: When calculating the 50,000 cells it takes roughly 2.5 hours to complete all calculations. So, for 3 years it will take roughly one work day of tying up my computer to just compile data that will then require several days of calculation/manipulation.
Question(s): Is there a way to speed this up to a reasonable amount of time (I'd even take 30 minutes at this point)? Or, is Excel simply the wrong tool to be using for this amount of data? Do I need a better machine to run these calculations? I am currently using a Dell XT3 with 2.5 Ghz i5 quad core processor.

From a large set of process data, I would like to copy those instances where there is indeed a measurement available to a different sheet automatically.
The original data looks like this:
Time Temperature
02-Jan-2010 11:41:50 156.1
02-Jan-2010 11:42:50
02-Jan-2010 11:43:50
02-Jan-2010 11:44:50 157.3
02-Jan-2010 11:45:50
02-Jan-2010 11:46:50 156.8
02-Jan-2010 11:47:50 156.4
02-Jan-2010 11:49:50
02-Jan-2010 11:50:50 157.2
The resulting data shoot look like this (in a different sheet):
Time Temperature
02-Jan-2010 11:41:50 156.1
02-Jan-2010 11:44:50 157.3
02-Jan-2010 11:46:50 156.8
02-Jan-2010 11:47:50 156.4
02-Jan-2010 11:50:50 157.2
I have actually been learning quite a few tricks on my own since I started this data analysis project but I believe this requires some experience with macros, which I really don't have.

I I have a excel document which has a sheet containing a large number of array formulas.
I turned the automatic calculation off.
However, even when I press F9 to calculate the cells it just crunches, gets stuck at “Calculating 0%” and then crashes.
The majority of the array formulas are IF queries with multiple criteria.
Would it speed up the calculation if I didn’t use array formulas?

could provide me a loop function in VBA for these calcultions.
Cell A1*E1 + B1*F1 + C1*G1
Cell A2*E1 + B2*F1 + C2*G1
......till
CellA100*E1 + B100*F1 + C100 * G1
These are the calculations for E1-G1.
The process must be repeated till E50-G50
So the second step is:
Cell A1*E2 + B1*F2 + C1*G2
Cell A2*E2 + B2*F2 + C2*G2
......till
CellA100*E2 + B100*F2 + C100 * G2

I have four named ranges (Segment, Keyword, Impressions and Dropdown) and I would like to create a formula-based ranking of keywords by impressions and clicks. Using the following array formula, I am able to return the correct values for impressions or clicks:
{=LARGE(IF(Segment=DropDown,Impressions),$H7)} where $H7 is the number ranking 1, 2, 3 etc.
My question is what array formula could be used to find which row in the array returned that number and then pulls the data from the same row in the other named ranges?
Essentially find row of {=LARGE(IF(Segment=DropDown,Impressions),$H7)} but return Keyword and Clicks on that row.
Other Notes: I cannot use pivot tables and some values might be the same which would make Vlookups not accurate for duplicate values.
Link to an example document to clarify this. [URL] .......

I need to be able to query a large date range by a small beginning and end date range and return a count when the value is = each search criteria. i.e. - Search one year of dates from a table by Beg: 7/23/2012 to End: 10/21/2012 and return a count. The beginning and end dates are dynamic and I will need to reference the cells, i.e. B102 "Beg" B102 "End" and not a static date.

I have a two dimensional array that I need to search, and copy a value to the sheet I am using.
Example Array
code1 name1
code2 name1
code3 name4
Sheet
ColumnA ColumnB
code2
code4
code1
code3
I need to fill in columnB with the corresponding name, leaving it blank if the code does not exisit in the array.
What I have attempted (unsuccessfully) so far is below. I keep getting an Error at the If DataArray(y, 0) = majorcode line.
Dim datatotalrows As Integer
Dim listtotalrows As Integer
Dim majorcode As String
Dim clientname As String
Dim y As Integer 'variable for array
Dim x As Integer 'variable for data
datatotalrows = Range("A1"). CurrentRegion.Rows.Count

Is there a way to find the last matching row in an array? For example, I can find the first matching row in an array by using the MATCH function. Is there a way to search through the array backwards?
Ex.
OrderID
10567
10569
10571
10573
10571
If I use =MATCH(10572, A2:A6,1), I will get the result "3". How can I get the result "5" (to tell me the row number of the last match)?
A more accurate example of what I am trying to do would be:
OrderID
1
1
1
3
3
3
If I feed the number 2 in as my search value, I want to know the range of rows where the OrderID is less than or equal to 2. In the case above, it would be rows (assuming "OrderID" is in row 1) 2 through 4. I can get "2" back by using =MATCH(2,A2:A7,1), but I don't know how to get "4".

I have a formula which I took from another post to return a particular value in a specified cell as follows;
=INDEX(A1:E9,M3+MIN(IF(A1:E9=K3,ROW(A1:E9)-3)),N3+MIN(IF(A1:E9=K3,COLUMN(A1:E9)-1)))
However I don't understand what the -3 and -1 does and I believe it is these entries that are causing the error.

4444EggsWaterFlourSugar
5555WaterMilkDirt
I looked for a way to represent my data in a cleaner way than this but couldn't find any tools....a point in the right direction would be helpful. I guess the old plug-in that converted Excel->HTML isn't available?
Column A is a finished product and B-D are the ingredients to make it however values in Column A are also ingredients (sometimes multiple times). I want a formula that searches for values in Column A within the table B1:D5 and returns an array, if possible, of the finished products where Column A was used.
For example, searching for Sugar would return "Flour, Water". Searching for Water would return "Milk, Eggs" (I'd rather not have Milk listed twice but beggars can't be choosers).

I wish to search for a substring within an array of strings and just return back an indication that the substring exists withing that array.
so for instance let the substring be "rang"
and let the array be
{"apple","orange","lemon"}.
I wish to put a single command line next to my substring and wish to search through that range and return a key code if it exists. And then I will repeat the same search for other substrings. For the moment being, I don't care too much about the number of occurences or the exact cell address where they occur. All I wish to know is whether they exist in that list or not.
So it looks to me it is like a SEARCH command but except on a range of text (Rather than a single text) with an array formula. I have tried MATCH but my case is not an exact match either.

i wish to have a result of the below.
there are random dates in a column say D6:D17 in the format of (10/02/2014), there could only be one date in this column array or there could be several, like:
1/02/2014
12/04/2014
17/06/2014
5/12/2014
i also have an aray below this in cells D19:D30 With the "A" column showing the months Jan to Dec.
i wish to look the array of D6:D17 and populate the below cells corresponding with the months only, see example below. the reason for this is i wish to then turn the cell green with conditional formatting if there is a date in that month fro the original array.
Date10/02/2014
Date10/04/2014
Date10/06/2014
Date10/08/2014
Date10/12/2014

I have a sheet with Names in it. I need to look those names up and find which org they belong to. The problem is the the names have many characters after them, and many names belong to a few orgs, with a the rest belonging to many orgs. (See below)
I have been trying to get a Vlookup to work, but since it can't go left, it won't look up the orgs that don't own at least three names. And I can't get the search to work on the names.
Names:
WSGHG1-8410YFH
WSSMXG-8401B8T
NBSMXG-0310V6R
NBXG-0310V6V

Here is the table I am working with
Date
Open
High
Low
Close
Volume
Adj Close
Semi-Annual Yield
Theoretical Bond Price
Index
Coupon
Total Value
Peaks
Troughs
[Code] ..........
The Relevant columns would be "Date" column A cell 1, "Total Value" column L cell 1, "Peaks" column M cell 1, and "Troughs" column N cell 1. What I basically want to do, in the next column, column O, is this: If cell N# = "Trough" find the previous M cell = "Peak" and take the L cell in that "Peak" row and subtract the L cell in the Trough row from it (like =(L4-L9)/L4)). Then in column P, if the percentage drop was 5% or greater, I want to find the days between the trough we are looking at, in cell n10, and the NEXT Peak, cell M11, using the corresponding dates in Column A.

I'm looking for a formula to search for a value in the SECOND (instead of first) column of a table array and return a value in the same row from FIRST (instead of the same or another) column in the table array. Formula would be searching for the unique production order number in the column B and return production line id from the column A.
A1 production line_id
B1 poduction_order_number
A2 L1
A3 L2
A4 L1
B2 505212
B3 504234
B4 505663
I was trying vlookup(504234;B2:A4;2;0) to make formula go search from right columns to the left but then excel is switching the search table to A2:B4 and gives #N/D!
One remark-there is no possibility to switch these 2 columns to simplify. I have to leave them as they are.

I want to search a data set and return the maximum value based on 3 criteria using (array) formulas.
Say the data set contained the following:
Row 1: column headings (date, name, data 1, data 2, data 3, etc)
Column A: dates
Column B: names
Columns C through G: data
I want to find the maximum value for a given name, in a certain month, and a nominated data column (e.g. data 2). For example:
Month = June
Name = Geoff
Data column = Data 2
Max value = ????
All of the data in the data columns is numeric.

I need to check each of 13,000 job titles to see if they include the string "VP".
For the time being, I want to find the most efficient way to check an individual title, before building an array or SUMPRODUCT function that will check all the titles in swoop.
So... I have tried:
=ISNUMBER(SEARCH(A1,B1))
..but it returns TRUE if A1 and B1 are both blank -- which they can be in my spreadsheet.
And I have tried:
=SIGN(SEARCH(A1,B1))
but it returns #N/A if A1 cannot be found within B1.
If I can, I want to avoid introducing an IF statement because, looking ahead, I am already concerned that this analysis will be complicated enough without multiple paths.
So.. what's the most efficient way to return a TRUE/FALSE, or 1/0, result depending on whether A1 is in B1?
EXTRA-CREDIT!
An extension of the above problem... arrays and SUMPRODUCTs welcome:
What's the most efficient way to return a TRUE/FALSE, or 1/0, result depending on whether (A1 or A2 or A3... or A99) is in B1?

Search Column A for a name (using an array if possible). If it finds this name, add a string of text to the AA cell on the same row that it found the name on.
For example,
If in A1 it finds the specified name. It then adds a string of text to AA1.

the task for the code below is to search through rows in array and check if there's no "text" in it like user inputed in box. But it always shows that there's no such email,i can't figure out the mistake, Maybe the problem is in the type the InputBox returns? But i've tried entering type := 2 (text),dunno what else i can do...I've also tried using p = InputBox("Please,eneter email!").

I have an array 20 Rows x 42 Columns, which contains a competition draw.
I need to search this array for a unique value and return whatever the time is in the first column on the same row as the value appears, and enter it into column C in the Womens Times sheet.
I also want to return into column D the court number from row 3.
The reason i want this automated is as teams enter / withdraw we may need to drag the games from court to court to fill gaps, so i want the Womens Times sheet to update accordingly.
I have been messing around with index and match, but cannot quite get it to return what i need.
I have attached an example ... on the sheet "Womens Times" in column A there is a list of game numbers ( #1W etc etc) indicating womens game #1 and so on. The main sheet i am using also has a seperate tab for the mens games, hence the designator of W or M on the end of the game number.
