Highlight Words from a Word List

by Allen Wyatt
(last updated September 11, 2021)

Paul has a document that he needs to check against a word list contained in another document. If the document being checked contains one of the words in the list, then the word in the document (not in the word list) needs to be highlighted by being made bold. The word list is large, on the order of 20,000 words, and Paul is wondering what the best way to do this is.

There are two ways you can proceed. The first is to write your own macro that will do the comparisons for you. If you put the words you want checked into a document named "checklist.doc" in the C: drive, then the following macro can be used:

Sub CompareWordList()
    Dim sCheckDoc As String
    Dim docRef As Document
    Dim docCurrent As Document
    Dim wrdRef As Object

    sCheckDoc = "c:\checklist.doc"
    Set docCurrent = Selection.Document
    Set docRef = Documents.Open(sCheckDoc)
    docCurrent.Activate

    With Selection.Find
        .ClearFormatting
        .Replacement.ClearFormatting
        .Replacement.Font.Bold = True
        .Replacement.Text = "^&"
        .Forward = True
        .Format = True
        .MatchWholeWord = True
        .MatchCase = True
        .MatchWildcards = False
    End With

    For Each wrdRef In docRef.Words
        If Asc(Left(wrdRef, 1)) > 32 Then
            With Selection.Find
                .Wrap = wdFindContinue
                .Text = wrdRef
                .Execute Replace:=wdReplaceAll
            End With
        End If
    Next wrdRef

    docRef.Close
    docCurrent.Activate
End Sub

All you need to do is have the document open that you want checked, and then run the macro. If the document containing the words to check is named differently or in a different location, just change the line that sets sCheckDoc so that it has a different full path name for the document.

Basically, the macro grabs each word from the word list and then does a Find and Replace operation using that word in the document. If you have many, many words in the word list, then the macro can take quite a while to run—20,000 Find and Replace operations is quite a few!

The other approach you can try is to use a third-party application to do the work for you. There is a good article and application available free at this site:

This approach is particularly interesting because it doesn't just make matched words bold, but allows you to set them to some color that you may desire.
