# Concatenate An Array (using Array Formula)

May 18, 2007

I just wanted to concatenate a few cells using an array formula like this:

{=SUM(IF(B2:J2="";0;B2:J2))}

Well, this does not work. I have no idea why it fails. Any solution to this without scripting?

## Concatenate Multiple Cells With Array Formula

Jan 21, 2009

If I have the following data set in cells A1:C9:

IDCommentFirst Unique
109876Low OilTRUE
109876Checked On 12/12FALSE
109877Checked on 12/15TRUE
109878Correct LevelTRUE
109877Correct LevelFALSE
109878PerfectFALSE
109877NewFALSE
109878Correct LevelFALSE

In the First Unique column (column C) I have formulas. In C2 I have this formula (and then I copied it down):

=COUNTIF(A\$2:A2,A2)=1

In cell E2, I have this formula to count unique occurrences:

=SUMPRODUCT(C2:C9*1)

In cell G2 I have this formula to extract unique records (entered with Ctrl + Shift + Enter):

=IF(ROWS(G\$2:G2)

## Converting 3x10 Array To A 1X30 Array To Run A Match Formula

Apr 7, 2009

Say I have 3 columns of data: A1:C10 and I want to run a Match() function on them all together to see if I get a match any one those cells, say the value of have in X1.

Since, Match only allows a One-Column lookup array.. is there a way to "concatenate" or "append" the 3 columns together within a formula so now I would be looking to Match in an array that is 1 column * 30 rows?

Basically want to convert =Match(X1,A1:C10,0) to =Match(X1,A1:A30,0) without moving around the raw data in the sheet.

And I want to avoid doing an AND or OR formula that uses 3 separate MATCH() for each column.

I have a hunch that the MMULT or MMULT/TRANSPOSE functions are involved, but can't seem to get it right.

## Index Match Array New Formula Not Array?

Nov 6, 2013

Is there anyway to recreate this formula w/o it being an array ?

{=IF(C3="","",IFERROR(INDEX('Master List'!\$B\$1:\$B\$2000,MATCH(TRUE,ISNUMBER(SEARCH('Master List'!\$A\$1:\$A\$2000,C3)),0)),"ADD TO MASTER"))}

## Array Concatenate Function VBA

Aug 8, 2012

I use a existing code and want to add the Concatenate in the code.

VB:
Sub Subtotal()

Dim myAreas As Areas, myArea As Range, x As String
Dim y As Long

Worksheets("INVOICE_hulp").Activate
Range("Q1").Select

[Code] ....

The array sum function works but Concatenate not. In Excel I get the formula Concatenate(H2:H3) in stead of Concatenate(H2,H3). What should I change to get the code working?

## Using Array Variable Instead Of Array Formula

Jun 30, 2006

i need to replicate what i did using array formulas with VBA macro (array variable). to make things clear and simple i created an example for illustration only. look at it & u will find what i did & what i need to do ,much of it
in writing so that i accurately describe my problem. attached is my example

## Concatenate Array Value From Cells For INDEX / MATCH?

Aug 2, 2012

Why this formula code:

Code:
=INDEX(INDIRECT(\$A\$3&D7&\$A\$4),MATCH(B7, INDIRECT(\$A\$3&D7&\$A\$5),0),5)

Where A3 D7 and A4 concatenate to form a workbookname!named range1 and equally A3 D7 and A5 form workbookname!named range2 works perfectly well for a fixed range as named range, but not if the named range is dynamic using the typical OFFSET, COUNTIF method?

I need to be able to concatenate the range reference in this way, but for the named range reference to be a dynamic range that will grow and change with additions etc.

## "You Cannot Change Part Of An Array" When Editing Array Formula

Aug 25, 2006

I am trying to copy or edit a cell thats has the following formula (see below), I keep getting this message "You cannot change part of an Array!"

=If(ROW(\$A2:\$A8)-ROW(A2)+1>COUNT(W2:W8),"",INDEX(\$A:\$A,SMALL(W2:W8,ROW(INDIRECT("1:"&ROWS(A2:A8))))))

## Treating String As Array And Correct Array Format For Unicode Characters?

Jul 30, 2012

in C a string is nothing more than an Array of characters ending with a null character.

in VBA this does not seem to be the case.I am trying to use the BlowFish code from David Midkiff for some encryption, however the code sometimes fails:

When encrypting a string a string of a specific length should be returned. however sometimes one of the characters of the encrypted string is a null character, and the returned encrypted string (with a embedded null character) is causing me problems. I want to check for the null character and if present redo the encryption. But how do I check for the presence of this null character in a unicode (double-byte) string?

Checking with Len(encrypted) gives the correct length (!) but trying to move each (unicode)character into an array fails when using the Mid() function past the null character in the string.

Now I can use

byteArray() = StrConv(unicodetext,vbFromUnicode)

to get the lower byte of each character into an array easily, but how do I do this for both bytes of the unicode characters?

Using an integer array does not work other than through

intArray(j) = CInt(AscW(Mid(Outp, j, 1)))

which fails on the nullstring in my encrypted text.

I have tried with variants but so far no luck. I thought if the string was entered into a variant then I could also address the variant as an array of bytes, but that does not seem to be accepted by VBA.

## Populate Multiple Array Variables With Same Code By Dynamically Changing Array Name

Sep 9, 2012

I am trying to populate many arrays with the same code using something like this. For this test, assume the following data in A1.

1
2
3
4
5

6
7
8
9
10

11
12
13
14
15

16
17
18
19
20

21
22
23
24
25

Code:
Sub populate()
Dim firstArr(5), secondArr(5), thirdArr(5), fourthArr(5), fifthArr(5) As Integer
Dim r, c, num As Integer

[Code]....

The above code does not work of course and falls over. I am unsure whether I should try and concatenate with something like this eg "" & arrName(i) = Cells (r,c) or go down a different route.

## String Array Values To Array Of User-Defined Types

I have a class module with several private variables, including one that is an array of a user-defined type. I am trying to set the values of a single element of this array with "Property Let ..." from a string array:

## VBA To Output From Array Based On Variable In One Element Of Array

May 2, 2013

I'm only starting to get to grips with arrays. I have what I consider to be a lot of data that I need to 'cut' into separate workbooks. I have written some code that does this by simply looping through each line, 250k+, checking against a variable and copying the row into a separate sheet. This took longer than it would have doing it manually. It was suggested to me that I use arrays to speed up the process. I have managed to store the test data into an array but am struggling to find a way to loop through and pull out an entire 'row' from the array based on a variable. I have looked for 2 days in various places to find some way to loop through the data held in the array, but to no avail.

That code will appear here from about 8am GMT tomorrow. I know that once I've cracked this I'm on the road to some very significant time saving and comprehensive report writing.

## Passing Array To OFFSET - Array Height Parameter

Aug 5, 2014

I want to pass an array to Offset in the "Height" parameter, without having to type the array.

{=MAX(SUBTOTAL(9,(OFFSET(A1,ROW(1:5),,{1,2,3,4,5}))))}

I can't seem to figure out how to build the {1,2,3,4,5}. I've tried another ROW(1:5) and have tried nesting that like N(ROW(1:5)) but nothing works.

How I can get the {1,2,3,4,5} without having to type it out (so that I can expand this to a larger list)??

## Filter An Array (the Longer One) Using The Shorter Array As The Criteria

Aug 26, 2009

I am trying to filter an array (the longer one) using the shorter array as the criteria. I am currently doing this using the following method

IF(LOOKUP(lookup cell, array)=lookupcell, lookupcell, "FALSE")

I then copy and paste 'values' and filter out the 'false' to get my final result.

This has worked in the past, but for some reason that I simply can't figure out, the formula isnt working! I've attached the example, and I've highlighted a number in blue (cell E522 and C103), (that should be being found in the 'LOOKUP' function) but is returning a "FALSE". I have looked over the code and simply can't figure out why Excel isn't returning the right value.

This is obviously happening for a quite a few of my numbers, as my filter result is returning an array that is about 1500 shorter than it should be. I have highlighted E522 as the 'example cell' to look at.

## Convert Boolean Array To Integer Array?

## Multiply Each Element In A 6x6 Array By A Similar 6x6 Array

Mar 22, 2007

I've tried to multiply each element in a 6x6 array by a similar 6x6 array, both on the same sheet, and it worked.(see Macro2 and attached xls file "Test").Then I got more ambitious and tried to do the multiplication from a standard array in sheet "TestA", with the result on the same sheet, by each array in sheet "TestB" and failed.How do I solve this problem? Pgualb PS:I'm using the R1C1 style.

## Creating Array From 2-dimensional Array

Nov 28, 2011

I'm new to arrays. They seem promising for what I want to do though...

Heres where I'm at. I have some data like this:

items freq 1 0.5 2 0.5 3 0.5 4 0.25 5 0.25 6 0.125

Now, I've created a 2 dimensional array, as such:

Code:
Sub testarray()
Dim arr1 As Variant
Dim rng1 As Range
Dim lngX As Long

Set rng1 = [A2:A6]
ReDim arr1(1 To rng1.Count, 1 To 2)
For lngX = 1 To rng1.Count
arr1(lngX, 1) = rng1.Cells(lngX, 1)
arr1(lngX, 2) = rng1.Cells(lngX, 2)
Next
End Sub

Now, what I need to do, is create an array for each freq of all the items that share that freq. Essentially I need this:

0.5 {1,2,3} 0.25 {4,5} 0.125 {6}

Now, I was thinking, if I could create a dictionary object and make the key the freq (so my keys would be 0.5,0.25,0.125) then I could assing the "item" an array (or another dictionary) holding the items that apply to that freq.

## Looking Up Row Array Data In Column Array

Jul 11, 2007

On one sheet (KPI) I have either the values "x" or "" in the range A84:A89 to mark wheter to use the corresponding project in the range B84:B89. On the sheet X-ref I have the same project names in range T4:Y4 and a corresponding target value in T8:Y8

What I want is the sum (or average) of the marked-projects target-values. The result should end up in KPI!G31.
In other words I want

=sumif(A84:A89;"x";'X-ref'!T4:Y4)

but it doesn't work since the first range is an column-array and the second range is an row-array.

## Return Array Elements From 2D Array

Feb 11, 2008

I'm trying to use an array to carry out string function on a range of excel cells.

Here is the code I am using

Dim arrXl As Variant

arrXl = ws.Range("F1:F" & ws.Range("D1").End(xlDown).Row)

For i = LBound(arrXl) To UBound(arrXl)
MsgBox (LBound(arrXl))
'If 1st char is different from 3rd char then remove all of string after 1st char

If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then
arrXl(i) = Left(arrXl(i), 1)
End If
'If 1st char is different from 7th char then delete string after 5th char
If Left(arrXl(i), 1) <> Mid(arrXl(i), 7, 1) Then
arrXl(i) = Left(arrXl(i), 5)
End If

The lbound function returns the value of 1 as the lower bound, I do not have "Option base 1" set so I was expecting the lbound value to be 0. The first 2 cells in the F column are blank so this may have something to do with it, I am unsure if cells in excel can be null if they can be null one cell may be null and the other may be a zero length string but I am unsure about this.

The ubound function returns a value of 487.

The code breaks when I try to access an element in the array so it breaks on the line:

If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then

and returns the "Subscript out of range" error message.

## Multiple A Logical Result Array With A Text Array And Return Text

Aug 6, 2009

I need to multiply an array of logical results ( returned as {1,0,0,0,1,0 et.}) with a text array (a reference column) and return the text in the reference column in case the value in the logical array is 1.

## VBA Find Partial String In Array And Output Found String Array Value?

Mar 31, 2014

I am trying to do a sort of index match thing using VBA. What I am attempting to do is to use the prefix of a long number and try to find that exact prefix in a string array, and output that string array value. So this is what I have so far as a test:

[Code].....

So I can match the text exactly so if I put PREFIXB in cell A1 in this example, i will get the msg box saying "YES", but if I make it PREFIXB1231k4j3jj1kj32cj, it will display "NO". I want to get it so that PREFIXB will be displayed in the cell that I put the formula in. So if A1 = "PREFIX1AAA100CF" and cell B1 = "=ABC(A1)", cell B1 will display "PREFIX1AAA".

Now the thing is that these prefixes can have different lengths, but will never encompass the exact prefix of another. So if I had a prefix of: PRE1AB, I won't have a prefix of PRE1A.

## Using An Array Formula To Sum

Mar 6, 2007

I want to use an array formula to sum about 5 rows each of which has 5 columns, e.g.

1 2 3 4 5 15
2 3 4 5 9 23
5 4 3 2 5 19
9 8 7 6 5 35
7 6 4 2 1 20

The final column is the total for each row. Instead of using =sum(a1:a5) then dragging the formula down thus creating a new formula for each line, I want to use a single array formula to achieve the same result. I have tried =sum(\$a\$1:\$a\$5:\$e\$1:\$e\$5), even though all my instincts said it did not look right. And I was right!

I'm sure it is easy, but I just cannot work out the syntax.

## Array Formula In V.B.A.

Aug 2, 2007

I have an formula for calculating the factor of a number this a fairly long array formula I decided to try to write this in vba to use as a user defined function. I first decided to record a macro of me writing the formula in excel to see what the code looked like, this I then adapted in another module copying the basic formula in a function procedure. my recorded macro works fine when I run it but my adapted function shows an error namely that the FormulaArray is not defined. I've tried all kinds of variations but with no success. how do I write an array formula in V.B.A.

## Array Formula

Oct 16, 2005

I have a list in excel that contains the same sku more than once on a
workbook in no paticular order, however i want to bring back the last
time that this sku appeared on the workbook for example:

SKU 271562 date counted 11 september
SKU 275555 date counted 12 september
SKU 271562 date counted 12 september
sku 255212 date counted 13 september
& so on
SKU 271562 date counted 11 october

The date range is only applicable to the date counted therefore i
cannot search via a date

## IF & MAX Formula With Array

Aug 27, 2009

The following formula works, but takes far too long for an efficient user to run (note the array):

{=(MAX(IF((\$B\$4:\$B\$50000=\$B4)*(\$I\$4:\$I\$50000=\$X\$1),1*\$J\$4:\$J\$50000)))}

B = Number Values (e.g. 3431003)
I = Simple Text Values (e.g. I, P)
J = Dates (e.g. 4/15/2009)

Is there a formula that would provide the same result in a quicker fashion?

Note: Unfortunatly, the data will get up to 50,000 rows.

## 3D Array Formula

## Can Formula Be Placed In An Array I.e. { } ?

Jun 1, 2007

Seems not.

For example,

=SUMPRODUCT({1,0,1,0},F24:F27)

is ok. But

=SUMPRODUCT({if(F24=1,1,0),0,1,0},F24:F27)

is not.

Why is this so or is there a way to go aroung this?
