The code is taken from this post.

Option Explicit

Sub CompareInterpolation()
    Dim wsOriginal As Worksheet, wsInterpol As Worksheet
    Dim rwOriginal As Long, rwOriginalMax As Long
    Dim rwInterpol As Long, rwInterpolMax As Long
    Dim arOriginal() As Variant, arInterpolData() As Variant, arInterpolResult() As Variant
    Const Limit As Single = 0.02
    Set wsOriginal = Worksheets("Original Data")
    Set wsInterpol = Worksheets("Intepolation")
    rwOriginalMax = wsOriginal.Range("A1").CurrentRegion.Rows.Count
    rwInterpolMax = wsInterpol.Range("A1").CurrentRegion.Rows.Count
    arOriginal = wsOriginal.Range("A1:E" & rwOriginalMax)
    arInterpolData = wsInterpol.Range("A1:B" & rwInterpolMax)
    wsInterpol.Range("K2:O" & rwInterpolMax).ClearContents
    arInterpolResult = wsInterpol.Range("K1:O" & rwInterpolMax)
    For rwInterpol = 2 To rwInterpolMax
        For rwOriginal = 2 To rwOriginalMax
            If Abs(Round(arInterpolData(rwInterpol, 1), 3) - arOriginal(rwOriginal, 1)) <= Limit _
             And Abs(Round(arInterpolData(rwInterpol, 2), 3) - arOriginal(rwOriginal, 2)) <= Limit Then
                arInterpolResult(rwInterpol, 1) = arOriginal(rwOriginal, 1)
                arInterpolResult(rwInterpol, 2) = arOriginal(rwOriginal, 2)
                arInterpolResult(rwInterpol, 3) = arOriginal(rwOriginal, 3)
                arInterpolResult(rwInterpol, 5) = arOriginal(rwOriginal, 5)
                Exit For
            End If
        Next rwOriginal
    Next rwInterpol
    wsInterpol.Range("K1:O" & rwInterpolMax) = arInterpolResult
End Sub
