Match two sheets to find differences - sql

Question

I have one document (two sheets) that I am trying to compare between. I have cleaned up the columns so both have our unique reference number in column A, the vendor expense in column B and the revenue in column C. I am trying to do an internal audit of sorts without going through every one individually.
One sheet contains data from two years whereas the other contains data from one year. It is not a definitive date so I didn't want to remove any.

How would I go about matching the unique identifier in column A and highlighting if there is a difference in the information in column B or C?

Answer 1

here is the code to do it in VBA
I suppose for both Sheet1 and Sheet2 that:
ColumnA is "Pro", ColumnB Gross Rate and ColumnC "Carrier Exp"
All headers are in Row1 and the data starts in row2
Here is the code:
Sub test()
Dim wb As Workbook
Dim ws1 As Worksheet, ws2 As Worksheet
Dim Lastrow As Long, Lastrow2 As Long
Dim i As Integer, j As Integer
Set wb = ThisWorkbook
Set ws1 = wb.Sheets("Sheet1")
Set ws2 = wb.Sheets("Sheet2")
Lastrow = ws1.Range("A" & Rows.Count).End(xlUp).Row
Lastrow2 = ws2.Range("A" & Rows.Count).End(xlUp).Row
For i = 2 To Lastrow
For j = 2 To Lastrow2
If ws1.Range("A" & i).Value = ws2.Range("A" & j).Value Then
If Not ws1.Range("B" & i).Value = ws2.Range("B" & j).Value Then
ws1.Range("B" & i).Interior.Color = vbYellow
ws2.Range("B" & j).Interior.Color = vbYellow
End If
If Not ws1.Range("C" & i).Value = ws2.Range("C" & j).Value Then
ws1.Range("C" & i).Interior.Color = vbYellow
ws2.Range("C" & j).Interior.Color = vbYellow
End If
End If
Next j
Next i
End Sub
