Hi @MD_Farhan1
Could you try the following Invoke code and let me know if it works:
LLM Generated Code. I’ve verified it as you can see below
INPUT:
Old.xlsx
The WORKFLOW:
INVOKE CODE:
Code:
' Clone the structure of dtNew for output
dtChanges = dtNew.Clone()
' Loop through each row in the new data
For Each newRow As DataRow In dtNew.Rows
Dim email As String = newRow("Email").ToString.Trim()
' Find matching row in old data
Dim oldRow As DataRow = dtOld.AsEnumerable() _
.FirstOrDefault(Function(r) r("Email").ToString.Trim() = email)
' If match found, compare columns
If oldRow IsNot Nothing Then
Dim isChanged As Boolean = False
For Each col As DataColumn In dtNew.Columns
If col.ColumnName <> "Email" Then
Dim newVal As String = newRow(col.ColumnName).ToString.Trim()
Dim oldVal As String = oldRow(col.ColumnName).ToString.Trim()
If newVal <> oldVal Then
isChanged = True
Exit For
End If
End If
Next
If isChanged Then
dtChanges.ImportRow(newRow)
End If
End If
Next
Argument:
Use Write Range to write the dt_Changed to Sheet2 of New.xlsx
OUTPUT:
The Output in Sheet2

Hi @MD_Farhan1
You can use a simple Query
dt_result = dt_input.AsEnumerable().Where(Function(x) Not dt_output.AsEnumerable().Any(Function(y) y.ItemArray.SequenceEqual(x.ItemArray))).CopyToDataTable()
I have tried with same inputs you have provided and it works
Output
Do mark it as solution if it helps 
check the argument of Invoke code.
You have mentioned dt_Change not dt_Changes. Obviously it will give an error.
