Comparing the two excel sheets using MACRO

Comparing the two excel sheets using MACRO

Step1:- Create one sample text file with data like below

Sno|EmployeeId|EmployeeName
1|23423|krishnaRaju
2|32423|Ranja
3|45653|venkat

 Step2:- Create one sample text file with different data like below

Sno|EmployeeId|EmployeeName
1|23423|krishnaRaju
2|7456|Ranja
3|45653|yhy

Step3:- Create one excel file and click Alt+F11 to display the macro space the past the below code

Sub Button1_Click()

'Declare variables here
Dim sh As Long
Dim Row As Long, col As Long
Dim max_Row As Long, max_Column As Long
Dim DataSh1 As String, DataSh2 As String, FP1 As String, FP2 As String
Dim outcome, lastRow, lastCol, colNum As Integer

            DataSh2 = CStr(ThisWorkbook.Sheets(3).Cells(Row, col))
            If DataSh1 <> DataSh2 Then
                ThisWorkbook.Sheets(2).Cells(Row, col).Interior.Color = vbYellow

    If cell.Value = "LOADDATE" Then cell.EntireColumn.Delete
        Next

End If

End Sub

Step4:- Run the code first it will asks to select the first source file again it will ask one more text file to load the second sheet, once two sheets are loaded one more new sheet will create and display the matched and unmatched rows with different colors as below

Sno	EmployeeId	EmployeeName
TRUE	TRUE	TRUE
TRUE	FALSE	TRUE
TRUE	TRUE	FALSE
