Add columns and lookup values in two different workbooks - excel

Question

I have three workbooks, Workbook A, Workbook B and Workbook C.
To Workbook A, I want to add two columns at the end and call them "Item code" and "store code". The existing fields in Workbook A are "Item Descr" and "Store Descr".
To populate the field "Item code", I have to perform a lookup against Workbook B which has the columns "Item code" and "Item Descr".
To populate the "store code" column in Workbook A, I have to perform a lookup against Workbook C which has the columns "store code"and "store Descr".
This is my code so far:
Sub Macro1()
Dim LastRow As Long
Dim LastCol As Long
Dim iRow As Long
Set ws = Sheet1 ' NOTE: Change this if your data is not in Sheet1.
With ws
LastRow = .Cells(.Rows.Count, 1).End(xlUp).Row
LastCol = .Cells(1, .Columns.Count).End(xlToLeft).Column
.Cells(1, LastCol + 1).Value = "Brand_item"
.Cells(1, LastCol + 2).Value = "Brand_code"
End With
Range("A2").Select
Selection.End(xlToRight).Select
Range("G2").Select
Windows("PE CLOSING OCT R2trial.xls").Activate
ActiveCell.FormulaR1C1 = _
"=INDEX([PEcodez.xlsx]Sheet1!R1C2:R2338C2,MATCH(RC[-3],
[PEcodez.xlsx]Sheet1!R1C1:R2338C1,0))"
Range("G2").Select
Selection.AutoFill Destination:=Range("G2:G2110")
Range("G2:G2110").Select
Range("G2").Select
Selection.Copy
Range(Selection, Selection.End(xlDown)).Select
Application.CutCopyMode = False
Selection.Copy
Range("G2").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
Range("H2").Select
Application.CutCopyMode = False
Windows("PE CLOSING OCT R2trial.xls").Activate
ActiveCell.FormulaR1C1 = _
"=INDEX([PEdoorcodes.xlsx]Sheet1!R1C3:R29C3,MATCH(RC[-7],[PEdoorcodes.xlsx]Sheet1!R1C1:R29C1,0))"
Range("H2").Select
Selection.AutoFill Destination:=Range("H2:H2110")
Range("H2:H2110").Select
Range("H2").Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Copy
Range("H2").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
Range("H2").Select
Application.CutCopyMode = False
End Sub
How do I include the file path of the workbooks?
Update, I tried the following code to update my path:
ActiveCell.FormulaR1C1 = _
"=INDEX(C:\Users\amy\Documents\amyTrial\[PEcodez.xlsx]Sheet1!$A:$A,MATCH(RC[-3],C:\Users\amy\Documents\amy\[PEcodez.xlsx]Sheet1!R1C1:R2338C1,0))"
It gives me
Application-defined or object-defined error.

I have created some dummy workbooks/data on my end, as you did not provide screenshots.
For me, this is "Sheet1" in workbook A,
this is "Sheet1" in workbook B.
and this is "Sheet1" in workbook C.
I use the code below to look up item descriptions and store descriptions. You will need to change the file paths to workbook B and C in the code itself (provided you place the code itself in workbook A and run it from there).
Option Explicit
Private Sub lookupDescriptions()
Dim pathToWorkbookB As String
pathToWorkbookB = "C:\Users\User\Desktop\New folder\3 workbooks\B.xlsx" ' Change this to the real file path.
Dim pathToWorkbookC As String
pathToWorkbookC = "C:\Users\User\Desktop\New folder\3 workbooks\C.xlsx" ' Change this to the real file path.
Dim workbookB As Workbook ' Contains: Item code, item descr
Set workbookB = OpenWorkbook(pathToWorkbookB)
If workbookB Is Nothing Then
MsgBox ("Could not locate workbook B at the path below" & vbNewLine & vbNewLine & pathToWorkbookB & vbNewLine & vbNewLine & "Check file path provided. Code will stop running now.")
Exit Sub
End If
Dim workbookC As Workbook ' Contains: Store code, store descr
Set workbookC = OpenWorkbook(pathToWorkbookC)
If workbookC Is Nothing Then
MsgBox ("Could not locate workbook C at the path below" & vbNewLine & vbNewLine & pathToWorkbookC & vbNewLine & vbNewLine & "Check file path provided. Code will stop running now.")
Exit Sub
End If
' Workbooks A and B both contain "Item code",
' Get "Item description" from workbook B for each match
With ThisWorkbook.Worksheets("Sheet1")
Dim itemCodesInA As Range
Set itemCodesInA = .Range("A2:A" & .Cells(.Rows.Count, 1).End(xlUp).Row)
Dim storeCodesInA As Range
Set storeCodesInA = .Range("B2:B" & .Cells(.Rows.Count, 1).End(xlUp).Row)
End With
With workbookB.Worksheets("Sheet1")
Dim itemCodesInB As Range
Set itemCodesInB = .Range("A2:A" & .Cells(.Rows.Count, 1).End(xlUp).Row)
Dim itemDescriptionsInB As Range
Set itemDescriptionsInB = .Range("B2:B" & .Cells(.Rows.Count, 1).End(xlUp).Row)
End With
' Workbooks A and C both contain "Store code",
' Get "Store description" from workbook C for each match
With workbookC.Worksheets("Sheet1")
Dim storeCodesInC As Range
Set storeCodesInC = .Range("A2:A" & .Cells(.Rows.Count, 1).End(xlUp).Row)
Dim storeDescriptionsInC As Range
Set storeDescriptionsInC = .Range("B2:B" & .Cells(.Rows.Count, 1).End(xlUp).Row)
End With
' This is workbook A, change sheet name if necessary
With ThisWorkbook.Worksheets("Sheet1")
Dim lastRow As Long
lastRow = .Cells(.Rows.Count, 1).End(xlUp).Row
Dim lastColumn As Long
lastColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column
.Cells(1, lastColumn + 1).Value2 = "Item description"
With .Range(.Cells(2, lastColumn + 1), .Cells(lastRow, lastColumn + 1))
.Formula = "=INDEX(" & itemDescriptionsInB.Address(True, True, xlA1, True) & ",MATCH(" & itemCodesInA(1).Address(False, True, xlA1, False) & "," & itemCodesInB.Address(True, True, xlA1, True) & ",0))"
.Value2 = .Value2 ' Comment/delete this line to keep formulas
End With
.Cells(1, lastColumn + 2).Value2 = "Store description"
With .Range(.Cells(2, lastColumn + 2), .Cells(lastRow, lastColumn + 2))
.Formula = "=INDEX(" & storeDescriptionsInC.Address(True, True, xlA1, True) & ",MATCH(" & storeCodesInA(1).Address(False, True, xlA1, False) & "," & storeCodesInC.Address(True, True, xlA1, True) & ",0))"
.Value2 = .Value2 ' Comment/delete this line to keep formulas
End With
End With
' Close workbooks without saving
If Not (workbookB Is Nothing) Then workbookB.Close False
If Not (workbookC Is Nothing) Then workbookC.Close False
End Sub
Private Function OpenWorkbook(ByVal fullPathToWorkbook As String) As Workbook
If Len(Dir$(fullPathToWorkbook, vbNormal)) = 0 Then
Exit Function
End If
Dim workbookName As String
workbookName = VBA.Strings.Mid$(fullPathToWorkbook, VBA.Strings.InStrRev(fullPathToWorkbook, "\", -1, vbBinaryCompare) + 1)
Dim outputWorkbook As Workbook
On Error Resume Next
Set outputWorkbook = Application.Workbooks(workbookName)
On Error GoTo 0
If outputWorkbook Is Nothing Then
Set outputWorkbook = Application.Workbooks.Open(fullPathToWorkbook)
End If
Set OpenWorkbook = outputWorkbook
End Function
What I get in workbook A (after running the code above) is:
Owing to the differences between your workbooks and mine, it is unlikely that the code will work for you as is. You will likely need to change/tweak the code in certain places, if:
your sheets in workbook A, B, C are named something other than "Sheet1"
your data (including headers) has a different location/structure/layout
there are blanks/missing items (that would cause the lookup to fail)
Nonetheless, the code and accompanying screenshots may give you an idea on how to do it.
