search entire Excel workbook for text string and highlight cell

Question

I need to search an entire Excel workbook containing multiple sheets for text strings that may be present in multiple columns (say in the range column A to column

Answer 1

This code, based on the first set of code you posted, will highlight all occurrences of whatever text you type in within the workbook.

Public Sub find_highlight()

    'Put Option Explicit at the top of the module and
    'Declare your variables.
    Dim FindString As String
    Dim wrkSht As Worksheet
    Dim FoundCell As Range
    Dim FirstAddress As String

    FindString = InputBox("Information")

    'Use For...Each to cycle through the Worksheets collection.
    For Each wrkSht In ThisWorkbook.Worksheets
        'Find the first instance on the sheet.
        Set FoundCell = wrkSht.Cells.Find( _
            What:=FindString, _
            After:=wrkSht.Range("A1"), _
            LookIn:=xlValues, _
            LookAt:=xlWhole, _
            SearchOrder:=xlByRows, _
            SearchDirection:=xlNext, _
            MatchCase:=False)
        'Check it found something.
        If Not FoundCell Is Nothing Then
            'Save the first address as FIND loops around to the start
            'when it can't find any more.
            FirstAddress = FoundCell.Address
            Do
                With FoundCell.Interior
                    .ColorIndex = 6
                    .Pattern = xlSolid
                    .PatternColorIndex = xlAutomatic
                End With
                'Look for the next instance on the same sheet.
                Set FoundCell = wrkSht.Cells.FindNext(FoundCell)
            Loop While FoundCell.Address <> FirstAddress
        End If

    Next wrkSht

End Sub

To find more than one value and format you could use the following code.
It relies on a sheet I've called Info which has the values to look for in the range A1:A3.
The background to these values have been coloured as you want and the code just finds the matching values and copies the colour over.

You could add extra code to allow for more values, or use a dynamic named range to return your source values.
A dynamic named range would consist of a formula such as: =Info!$A$1:INDEX(Info!$A:$A,COUNTA(Info!$A:$A)) with a given name of 'SourceValues'.
Select Define Name on the Formula ribbon and paste the formula into the Refers To: box and the SourceValues into the name.

You'd then refer to the range with Set Information = Range("SourceValues")

Public Sub find_highlight()

    'Put Option Explicit at the top of the module and
    'Declare your variables.
    Dim FindString As String
    Dim wrkSht As Worksheet
    Dim FoundCell As Range
    Dim FirstAddress As String
    Dim InfoBit As Range
    Dim Information As Range

    Set Information = Range("SourceValues")
    'Set Information = ThisWorkbook.Worksheets("Info").Range("A1:A3")

    'Use For...Each to cycle through the information we're looking for.
    For Each InfoBit In Information
        'Use For...Each to cycle through the Worksheets collection.
        For Each wrkSht In ThisWorkbook.Worksheets
            'Ignore the "Info" sheet as it holds our values to search for.
            If wrkSht.Name <> "Info" Then
                'Find the first instance on the sheet.
                Set FoundCell = wrkSht.Cells.Find( _
                    What:=InfoBit, _
                    After:=wrkSht.Range("A1"), _
                    LookIn:=xlValues, _
                    LookAt:=xlWhole, _
                    SearchOrder:=xlByRows, _
                    SearchDirection:=xlNext, _
                    MatchCase:=False)
                'Check it found something.
                If Not FoundCell Is Nothing Then
                    'Save the first address as FIND loops around to the start
                    'when it can't find any more.
                    FirstAddress = FoundCell.Address
                    Do
                        'Copy all formatting - bit of screen flicker.
'                        InfoBit.Copy
'                        FoundCell.PasteSpecial Paste:=xlPasteFormats

                        'Just copy the Interior colour.
                        FoundCell.Interior.Color = InfoBit.Interior.Color

                        'Look for the next instance on the same sheet.
                        Set FoundCell = wrkSht.Cells.FindNext(FoundCell)
                    Loop While FoundCell.Address <> FirstAddress
                End If
            End If
        Next wrkSht
    Next InfoBit
