I am trying 2 compare 2 workbooks loops but it is taking time. I want to compare 2 workbooks and find the differences Colud you pleas help on this.
Below is the code for loops


VBA Code:
Public Function ExcelCmp(firstFile, secondFile, resultFile)
' Declaring varaibles
Dim objExcel1, objExcel2, objSpread1, objSpread2
Dim strCount, x1, x2, y1, y2, maxR, maxC, DiffCount, PDiffCount, limit, RowID
Dim cf1, cf2, fOffset, resOffSet, sMsg
Dim arrCol
    Dim keepColumn As Boolean
    Dim columnHeading As String
Dim returnVal  'As Boolean

returnVal = False
limit = 1
' Creates object of the two Excel files
Set objExcel1 = CreateObject("Excel.Application")

resOffSet = 2

    Set resBook = objExcel1.Workbooks.Add

    Set resWorkSheet = resBook.Worksheets("Result")
  
    'ID

How to fill five years of quarters?
Type 1Q-2023 in a cell. Grab the fill handle and drag down or right. After 4Q-2023, Excel will jump to 1Q-2024. Dash can be any character.

Hi Radhasweety and Welcome to the Board! A few things, why are U creating another XL application rather than just opening wbs? How do you want the differences displayed and in what wb? Here's some code that I had previous. You will need to adjust the filepaths. This code indicates differences in the comparison wb (see code notes). To return the comparison wb to normal, comment out the blue and yellow lines of code and remove the comment from both "white" lines of code. HTH. Dave
Code:
Public Sub Compare2Wbs()
Dim RowCnt As Double, ColCnt As Double, OrigWb As Object, CompareWb As Object
Dim LastRow As Double, LastCol As Double, Sht As Worksheet, StartTemp As Variant
'*Ensures sheet data in CompareWb is the same as OrigWb
' CompareWb cell(s) are blue in CompareWb IF data exists in OrigWb AND
'         the data is NOT the same in the CompareWb
' CompareWb cell(s) are yellow IF data exists in CompareWb
'                        that did NOT originally exist in OrigWb

On Error GoTo FixEr
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
'change file address to suit
Set OrigWb = Workbooks.Open("D:\test.xlsm")
Set CompareWb = Workbooks.Open("D:\Test2.xlsm")
'turn CompareWb cell(s) blue IF data exists in OrigWb AND
'         the data is NOT the same in the CompareWb
For Each Sht In OrigWb.Worksheets
'use StartTemp to set usedrange. Restore A1 @ end with StartTemp
'   (ie. need A1 cell filled to set usedrange)
StartTemp = OrigWb.Sheets(Sht.Name).Cells(1, 1) 'temp store A1
If OrigWb.Sheets(Sht.Name).Cells(1, 1) = vbNullString Then
