Find the Difference in two cells (or Columns), and Highlight/Change Color of Difference

[abro16]

For Example:
I have a text in cell A1 "I have a cat." and in cell B1 "I have a dog." now excel formula or VBA code compare both cells and highlight the specific difference.
in above case, dog and cat should be highlight in same cell.
.
Or another example (one step ahead), if we have data in Number format.
If I have number like "123456789" in cell A1 and "128456789" in cell B1. both looks similar...
but in cell B1 there is one typo mistake at place 3.
Excel compare both cells, and highlight/or change font color/and bold, the specific difference.
in above case... 3rd place digit (in same cell) should be highlight, as in both cells it does not match.
.
Real life scenario is .. if we have data in one column with Original Number (say some Social Security Number, or Contact No.), but in column B, we have same number but with little typo mistake...
maybe somwhere one digit difference, or two digits difference, or might be more... So how to know comparing both columns.... what is actual difference.

*Remember: whole cell should not be highlighted. as we already know. both cells have minor difference.
but we want to know EXACT WHAT IS DIFFERENCE....

Hi and Welcome to the MrExcel forum. Please accept my warmest greetings and sincere hope that all is well.

Your description says that your data is in column A-B, but in your image the data is in column J-K.
I prepared the macro for the data in column J-K, but if it is another, it is very easy to make the change, just adjust the columns in this line of the macro:

With Range("J2", Range("K" & Rows.Count).End(3))

Run this macro:

Sub HighlightDifference()
  Dim c As Range
  Dim j As Long
  
  With Range("J2", Range("K" & Rows.Count).End(3))
    .Font.ColorIndex = xlAutomatic
    .Font.Bold = False
    
    For Each c In .Columns(1).Cells
      For j = 1 To Len(c.Value)
        If Mid(c.Value, j, 1) <> Mid(c.Offset(, 1).Value, j, 1) Then
          With c.Characters(j, 1).Font
            .Color = vbRed
            .Bold = True
          End With
          With c.Offset(, 1).Characters(j, 1).Font
            .Color = vbBlue
            .Bold = True
          End With
        End If
      Next
    Next
  End With
End Sub

HOW TO INSTALL MACROs
------------------------------------
If you are new to macros, they are easy to install and use. To install it, simply press ALT+F11 to go into the VB editor and, once there, click Insert/Module on its menu bar, then copy/paste the above code into the code window that just opened up. That's it.... you are done. To use the macro, go back to the worksheet with your data on it and press ALT+F8, select the macro name (HighlightDifference) from the list that appears and click the Run button. The macro will execute and perform the action(s) you asked for. If you will need to do this again in this same workbook, and if you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "Yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.

Note XL2BB:
For the future, it would help greatly if you could give us the sample data in a form that we can copy to test with, rather that a picture.
MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here: XL2BB Add-in
Note that there is also a "Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.

For example:

	A								I	J	K
1
2										4310592542883	4310592542993
3										1245689232345	1245689232845
4										4322223104983	4322223109983
