Formatting List of Text Strings in Excel - vba

Question

I am trying to turn the font to red for the occurrences of a list of words in excel. So far, I am able to find a single word, but I need to search for a whole array. I am a newbie with VBA and struggling. So far, I've been able to find this as a solution, but it deals with finding a single string, "F1":
Sub test4String2color()
Dim strTest As String
Dim strLen As Integer
strTest = Range("F1")
For Each cell In Range("A1:D100")
If InStr(cell, strTest) > 0 Then
cell.Characters(InStr(cell, strTest), strLen).Font.Color = vbRed
End If
Next
End Sub
Edit:
The cells I need highlighted have the items listed in comma separated format. For example, "Apple 1, Apple 3, Banana 4, Orange". The list of values to search from are in Different cells, "Apple", "Banana 4". I only want to highlight "Banana 4" because this is an EXACT match with the comma separated values. In the current formulation, the text that says "Apple 1" or "Apple 4" would be partially highlighted.
Edit 2:
This is the actual format from my workbook:

This is a method to achieve what you desire by looping through a range, collection, and array.
The code will find matches between the collection (your chosen match words) and the array (the string of words delimited in each cell). If a match is found, the starting and ending characters in the string are set and the characters between those values are colored.
Sub ColorMatchingString()
Dim ws As Worksheet: Set ws = ThisWorkbook.Sheets(1)
Dim strTest As Collection: Set strTest = New Collection
Dim udRange As Range: Set udRange = ws.Range("AC2:AC311") 'Define Search Ranges
Dim myCell, myMatch, myString, i
Dim temp() As String, tempLength As Integer, stringLength As Integer
Dim startLength as Integer
For Each myMatch In udRange 'Build the collection with Search Range Values
strTest.Add myMatch.Value
Next myMatch
For Each myCell In ws.Range("A2:AB1125") 'Loop through each cell in range
temp() = Split(myCell.Text, ", ") 'define our temp array as "," delimited
startLength = 0
stringLength = 0
For i = 0 To UBound(temp) 'Loop through each item in temp array
tempLength = Len(temp(i))
stringLength = stringLength + tempLength + 2
For Each myString In strTest
'Below compares the temp array value to the collection value. If matched, color red.
If StrComp(temp(i), myString, vbTextCompare) = 0 Then
startLength = stringLength - tempLength - 1
myCell.Characters(startLength, tempLength).Font.Color = vbRed
End If
Next myString
Next i
Erase temp 'Always clear your array when it's defined in a loop
Next myCell
End Sub

In keeping with your original code, you can just add another For each cell in Range (and a few other things):
Sub test4String2color()
Dim wb As Workbook
Dim ws As Worksheet
Dim strLen As Integer
Dim i As Long
Dim tst As Range
Set wb = ActiveWorkbook
Set ws = wb.ActiveSheet
Dim keyWordRng As Range
Dim dataRng As Range
Set keyWordRng = ws.Range("F1:F2")
Set dataRng = ws.Range("A1:A5")
For Each tst In keyWordRng
Debug.Print "Searching for: " & tst
For Each cell In dataRng
If tst.Value = cell.Value Then
cell.Characters(InStr(cell, tst), strLen).Font.Color = vbRed
ElseIf InStr(1, cell.Value, ",") > 0 Then
getWordsInCell cell, tst.Value
End If
Next cell
Next tst
End Sub
Sub getWordsInCell(ByVal cel As Range, keyword As String)
Dim words() As String
Dim keywordS As Integer, keywordE As Integer
words = Split(cel.Value, ",")
Dim i As Long
For i = LBound(words) To UBound(words)
Debug.Print "Found multiple words - one of them is: " & words(i)
If Trim(words(i)) = keyword Then
keywordS = ActiveWorkbook.WorksheetFunction.Search(keyword, cel, 1)
keywordE = ActiveWorkbook.WorksheetFunction.Search(",", cel, keywordS)
cel.Characters(keywordS, (keywordE - keywordS)).Font.Color = vbRed
End If
Next i
End Sub
Please note I added to ranges (keyWordRng and dataRng) which you will need to tweak for your sheet. This should (fingers crossed) work!
