How to find and replace part of a cell with formatted text

Question

In an Excel 2007 spreadsheet I want to find-replace with highlighting part of the text in a cell. Using find-replace reformats the entire cell though.

For ex

Answer 1

To make the search item case agnostic you can use:

Sub FormatSelection()

Dim cl As Range
Dim SearchText As String
Dim StartPos As Integer
Dim EndPos As Integer
Dim TestPos As Integer
Dim TotalLen As Integer

On Error Resume Next
Application.DisplayAlerts = False
SearchText = Application.InputBox _
(Prompt:="Enter string.", Title:="Which string to format?", Type:=2)
On Error GoTo 0
Application.DisplayAlerts = True
If SearchText = "" Then
Exit Sub
Else
For Each cl In Selection
  TotalLen = Len(SearchText)
  StartPos = InStr(Ucase(cl), Ucase(SearchText))
  TestPos = 0
  Do While StartPos > TestPos
    With cl.Characters(StartPos, TotalLen).Font
      .FontStyle = "Bold"
      .ColorIndex = 3
    End With
    EndPos = StartPos + TotalLen
    TestPos = TestPos + EndPos
    StartPos = InStr(TestPos, cl, SearchText, vbTextCompare)
  Loop
Next cl
End If
End Sub
