Excel - Comparing two cells from different spreadsheets

December 2016





Issue

Consider the following situation:
Spreadsheet A
Sheet1

Name Expenses Date Project 
John 10 23/10/2011 (Get data from Spreadsheet B)
Mark 50 12/5/2011 (Get data from Spreadsheet B)
Patricia 34 4/11/2011 (Get data from Spreadsheet B)
Anthony 88 19/3/2011 (Get data from Spreadsheet B)
Mark 20 5/7/2011 (Get data from Spreadsheet B)

Spreadsheet B
Sheet1

Name Project Date 
Mark Painting 12/5/2011
Anthony Singing 19/3/2011
Patricia Teaching 4/11/2011
Mark Reading 5/7/2011
John Painting 23/10/2011


What I need is to get the name of the project from Spreadsheet B (sheet1) and add to the column PROJECT in Spreadsheet A (sheet1). How to automate this process?

Solution

Try this
Sample Call :
=projectLookup(A2,C2) 

A2= Cell in which name is found
C2= cell in which date is found
Sheet1: name where the information about project is present

Option Explicit

Public Function projectLookup(nameCell As Range, dateCell As Range) As String

Dim sourceSheet As String
Dim nameRow As Long
Dim maxRows As Long

sourceSheet = "Sheet1"
projectLookup = vbNullString
With Sheets(sourceSheet)
maxRows = getItemLocation("*", .Cells)
If maxRows = 0 Then Exit Function
nameRow = 1

Do
nameRow = getItemLocation(nameCell.Value, .Range(.Cells(nameRow, "A"), .Cells(maxRows, "A")), bLastOccurance:=False)
If (nameRow > 0) Then
If (.Cells(nameRow, "C") = dateCell) Then
projectLookup = .Cells(nameRow, "B")
nameRow = 0
ElseIf (nameRow = maxRows) Then
nameRow = 0
Else
nameRow = nameRow + 1
End If
End If
Loop While (nameRow <> 0)
End With
End Function

Public Function getItemLocation(sLookFor As String, _
rngSearch As Range, _
Optional bFullString As Boolean = True, _
Optional bLastOccurance As Boolean = True, _
Optional bFindRow As Boolean = True) As Long

'find the first/last row/column within a range for a specific string

Dim Cell As Range
Dim iLookAt As Integer
Dim iSearchDir As Integer
Dim iSearchOdr As Integer

If (bFullString) _
Then
iLookAt = xlWhole
Else
iLookAt = xlPart
End If
If (bLastOccurance) _
Then
iSearchDir = xlPrevious
Else
iSearchDir = xlNext
End If
If Not (bFindRow) _
Then
iSearchOdr = xlByColumns
Else
iSearchOdr = xlByRows
End If

With rngSearch
If (bLastOccurance) _
Then
Set Cell = .Find(sLookFor, .Cells(1, 1), xlValues, iLookAt, iSearchOdr, iSearchDir)
Else
Set Cell = .Find(sLookFor, .Cells(.Rows.Count, .Columns.Count), xlValues, iLookAt, iSearchOdr, iSearchDir)
End If
End With

If Cell Is Nothing Then
getItemLocation = 0
ElseIf Not (bFindRow) _
Then
getItemLocation = Cell.Column
Else
getItemLocation = Cell.Row
End If
Set Cell = Nothing

End Function
