how to CONCATENATE different cells based on same sku - excel

I have a csv with 2 columns
sku,color
001,blue
001,red
001,pink
001,yellow
002,blue
002,red
002,pink
002,yellow
etc..
how can i create a new cell and combine the colors based on sku number? like this:
sku,combinedColors
001,"blue,red,pink,yellow"
002,"blue,red,pink,yellow"
thanks

There isn't a single formula that will do this and a macro is the best way.
But there is a way to do it with 2 formulas.
Open the CSV in Excel and you MUST sort column A ascending/descending.
Then in C2 , add this formula and drag it down
=IF(A2<>A1,B2,C1 & "," & B2)
in D2 ,add this formula and drag it down
=IF(A2<>A3,CONCATENATE(A2,",""",C2,""""),"")
Put the Autofilter on Row 1 and select NON BLANKS in column D.
You can then copy column D as you wanted!

You can do this with a VBA Macro. To enter this Macro (Sub), alt-F11 opens the Visual Basic Editor.
Ensure your project is highlighted in the Project Explorer window.
Then, from the top menu, select Insert/Module and
paste the code below into the window that opens.
You may want to make some changes depending on the location of your source data and where you want the results written. The macro assumes your source data is in columns A:B with a header row, and that your results will be written in columns D:E
I also assumed, since this is tagged with Excel, that you have imported the csv data into excel and you want the results in two columns.
To use this Macro (Sub), alt-F8 opens the macro dialog box. Select the macro by name, and .
Option Explicit

Set rRes = Range("D1")
'Unique SKU's
Set colSKU = New Collection
On Error Resume Next
For I = 2 To UBound(vSrc)
colSKU.Add Item:=CStr(vSrc(I, 1)), Key:=CStr(vSrc(I, 1))

On Error GoTo 0

For I = 1 To colSKU.Count
vRes(I + 1, 1) = colSKU(I)
For J = 2 To UBound(vSrc)
If vSrc(J, 1) = vRes(I + 1, 1) Then _
vRes(I + 1, 2) = vRes(I + 1, 2) & ", " & vSrc(J, 2)
Next J
vRes(I + 1, 2) = Mid(vRes(I + 1, 2), 2)

How do I copy column where column header is "Testing"

I am new to VBA and am trying to copy the column from Row 2 onwards where the column header (in Row 1) contains a certain word- "Unique ID".
Currently what I have is:
Dim lastRow As Long
lastRow = ActiveWorkbook.Worksheets("Sheets1").Range("A" & Rows.Count).End(xlUp).Row
Sheets("Sheets1").Range("D2:D" & lastRow).Copy
But the "Unique ID" is not always in Column D
You can try following code, it loops through first row looking for a specified header:
Sub CopyColumnWithHeader()
Dim i As Long
Dim lastRow As Long
For i = 1 To Columns.Count
If Cells(1, i) = "Unique ID" Then
lastRow = Cells(Rows.Count, i).End(xlUp).Row
Range(Cells(2, i), Cells(lastRow, i)).Copy Range("A2")
Exit For
End If
Next
End Sub
When you want to match info in VBA you should use a dictionary. Additionally, when manipulating data in VBA you should use arrays. Although it will require some learning, below code will do what you want with minor changes. Happy learning and don't hesitate to ask questions if you get stuck:
Option Explicit

'if you don't dim a var in vba it will be set as variant wich will sooner than you think give you a lot of headaches

'Set some vars and get data from sheets in arrays
'''''''''''''''''
'as the default is variant I don't need to add "as variant"
Dim arr, arr2, arr3, j As Long, i As Long, dict As Object
'when creating a dictionary we can use early and late binding
'early binding has the advantage to give you "intellisense"
'late binding on the other hand has the advantage you don't need to add a reference (tools>references)
Set dict = CreateObject("Scripting.Dictionary") 'create dictionary lateB
dict.CompareMode = 1 'textcompare

'e.g. we could now copy cel by cel to the new sheet => Sheets(arr(j,1).Range(... but this would create significant overhead
'so we'll use an intermediate array (arr3) to store the results
'We use a "dictionary" to match values in vba because this allows to easily check the existence of a value
'Together with arrays and collections these are probably the most important features to learn in vba!
For j = 1 To UBound(arr) 'traverse source, ubound allows to find the "lastrow" of the array
If Not dict.Exists(arr(j, 1)) Then 'Check if value to lookup already exists in dictionary
dict.Add Key:=arr(j, 1), Item:=arr(j, 1) 'set key if I don't have it yet in dictionary
End If
Next j 'go to next row. in this simple example we don't travers multiple columns so we don't need a second counter (i)

how to divide data in excel

There is an excel issue where we have one column with values like below and we want the respective values to go into corresponding new columns like allocation, primary purpose etc.
data is like
Allocation: Randomized|Endpoint Classification: Safety/Efficacy Study|Intervention Model: Parallel Assignment|Masking: Double Blind (Subject, Caregiver)|Primary Purpose: Treatment
Allocation: Randomized|Primary Purpose: Treatment
Allocation: Randomized|Intervention Model: Parallel Assignment|Masking: Open Label|Primary Purpose: Treatment
There are many such rows like this.
First use text to columns to split data using | delimiter.
Assuming data layout as in screenshot:
Add the following in A6 and drag across/down as required:
=IFERROR(MID(INDEX(1:1,0,(MATCH("*"&A$5&"*",1:1,0))),FIND(":",INDEX(1:1,0,(MATCH("*"&A$5&"*",1:1,0))),1)+2,1000),"")
It uses the MATCH/INDEX function to get the text of cell containing the heading, then uses MID/FIND function to get the text after the :. The whole formula is then enclosed in IFERROR so that if certain rows do not contain a particular header item, it returns a blank instead of #N/A's
You did not ask for a VBA solution, but here is one anyway.
Determine the column headers by examining each line and generate a unique list of the headers, storing it in a dictionary
You can add a routine to sort or order the headers
Create a "results" array and write the headers to the first row, using the dictionary to store the column number for later lookup
examine each line again and pull out the value associated with each column header, populating the correct slot in the results array.
write the results array to a "Results" worksheet.
In the code below, you may need to rename the worksheet where the source data resides. The Results worksheet will be added if it does not already exist -- feel free to rename it.
Test this on a copy of your data first, just in case.
Be sure to set the reference to Microsoft Scripting Runtime (Tools --> References) as indicated in the notes in the code.

String split and count in Excel

I have the following column K in Excel:
K
2 Apps -
3 Appointed CA - Apps - Assist - Appointed NA - EOD Efficiency
4 Appointed CA -
5 Appointed CA -
I want to split at - and count the number occurrences of the specific words in the string.
I tried the following formula which splits my string and returns everything LEFT to the -
=LEFT( K2, FIND( "-", K2 ) - 2 )
But the ideal output should be:
Apps Appointed CA Assist Appointed NA EOD Efficiency
1
1 1 1 1 1
1
1
Based on the above data.
Regards,
Here is a VBA macro that will
Generate a unique list of phrases from all of the data
Create the "header row" containing the phrases for the output
Go through the original data again and generate the counts for each phrase
As written, the macro is case insensitive. To make it case sensitive, one would have change the method of generating the unique list -- using the Dictionary object instead of a collection.

Assuming result range starts in column L:

etc.
Autofill downwards.
EDIT:
Assuming all possible string combinations we're looking for are known ahead of time, the following should work. If the possible string combinations are not known, I would recommend building a UDF to sort it all out.
Anyway, assuming the strings are known, following the same principle as above:
L2: =IF(FIND("Apps", K2, 1) <> 0, (LEN(K2) - LEN(SUBSTITUTE(K2, "Apps", "")) / LEN(K2)), "")
M2: =IF(FIND("Appointed CA", K2, 1) <> 0, (LEN(K2) - LEN(SUBSTITUTE(K2, "Appointed CA", "")) / LEN(K2)), "")
Increase for as many strings as you like, autofill downwards.

Splitting specific information in one excel cell to several others

I need to find a way to split some data on excel: e.g.
If a cell has the following in: LWPO0001653/1654/1742/1876/241
All of the info after the / should be LWPO000... with that number.
Is there anyway of separating them out and adding in the LWPO000in? So they come out as LWPO0001653
LWPO0001654
etc etc
I could do manually yes, but i have thousands to do so would take a long time.
Appreciate your help!
Here is a solution using Excel Formulas.
With your original string in A1, and assuming the first seven characters are the one's that get repeated, then:
B1: =LEFT($A1,FIND("/",$A1)-1)
C1: =IF(LEN($A1)-LEN(SUBSTITUTE($A1,"/",""))< COLUMNS($A:A),"",LEFT($A1,7)&TRIM(MID(SUBSTITUTE(MID($A1,8,99),"/",REPT(" ",99)),(COLUMNS($A:A))*99,99)))
Select C1 and fill right as far as required. Then Fill down from Row 1
EDIT: For a VBA solution, try this code. It assumes the source data is in column A, and puts the results adjacent starting in Column B (easily changed if necessary). It works using arrays within VBA, as doing multiple worksheet read/writes can slow things down. It will handle different numbers of splits in the various cells, although could be shortened if we knew the number of splits was always the same.

I'm clearly missing the point :-) but anyway, in B1 and copied down to suit:
=SUBSTITUTE(A1,"/","/"&LEFT(A1,7))
Select ColumnB, Copy and Paste Special, Values over the top.
Apply Text to Columns to ColumnB, Delimited, with / as the delimiter.
There's a couple of ways to solve this. The quickest is probably:
Assuming that the data is in column A:
Highlight the column, go to Data>>Text To Columns
Choose "Delimited" and in the "Other" box, put /
Click ok. You'll have your data split into multiple cells
Insert a column at B and put in the formula =Left(A1, 7)
Insert a column at C and pit in formula =Right(A1, Length(A1)-7)
You'll now have Column B with your first 7 characters, and columns B,C,D,E,F, etc.. with the last little bit. You can concatenate the values back together for each column you have with =Concatenate(B1,C1), =Concatenate(B1,D1), etc..

This is what is happening:
1) Set range to process

4) Skip the first record and concatenate "LWPO000" plus the current string to adjacent cells.

Excel transpose formula

I've been wraping my head around it for some time and just don't know how to approach this problem. My table consists of groups of data which I want to transpose from rows to columns. Every row has an index number in first column and all of the rows in one group have the same index.
1 a
1 b
1 c
1 d
1 e
1 f
1 g
1 h
2 as
2 bs
2 cs
5 ma
5 mb
5 mc
5 md
and I want my final result to be:
1 a b c d e f g h
2 as bs cs
5 ma mb mc md
is it possible to do this with formulas or do I have to do it in VBA?

Yes its possible. You would need the following functions:
IF
MATCH
ISNA
INDEX
Assume you have the data in sheet 1 in columns A and B:
C1:
place the value "1" in cell C1
C2:
=C1+1
drag down as much as needed
D1
=MATCH(C1,A:A, 0)
Drag down as much as cell C2
E1
=MATCH(C1,A:A, 1)
Drag down as much as cell C2
Sheet 2:
Now place the following formulas in cell A1 in sheet2:
=IF(ISNA(Sheet1!$D1), "", IF(Sheet1!$D1="", "", IF(COLUMN()-1+Sheet1!$D1 <=Sheet1!$E1, INDEX(Sheet1!$B:$B, COLUMN()-1+Sheet1!$D1), "")))
