Excel VBA to test and color cells of specific columns - excel

Question

So I have some "working code". Specifically, I am looking at a Range in Excel, then if I see "Yes" in a cell, coloring it Yellow and doing it for all the other cells in the range. Works GREAT.
Now I would like to sort of tweak the Fixed Range and have Excel look at the each column header and only perform this coloring based on the suffixes that I say. In this case, I would only like it to do this evaluation on the columns ending in "_ty".
Here is the code I have to color the entire range of cells:
Sub ColorCellRange()
Dim c As Range
' Loop through all cells in range A1:E + last used Row in column A
For Each c In Range("A1:E" & Range("A" & Rows.Count).End(xlUp).Row)
'Look for Yes
If InStr(1, c.Text, "Yes", vbTextCompare) > 0 Then
'Color the cell RED
c.Offset(0, 0).Interior.Color = vbYellow
End If
Next
End Sub
Current output of code

Answer 1

Another approach: scan the column headers and decide if to process the cells below.
Sub ColorCellRange()
Dim c As Range, hdr As Range, ws As Worksheet
Set ws = ActiveSheet 'or whatever
'loop over all headers in Row 1
For Each hdr In ws.Range("A1", ws.Cells(1, Columns.Count).End(xlToLeft)).Cells
If hdr.Value Like "*_ty" Then 'is this a header we're interested in ?
For Each c In ws.Range(hdr.Offset(1), ws.Cells(Rows.Count, hdr.Column).End(xlUp)).Cells
If InStr(1, c.Text, "Yes", vbTextCompare) > 0 Then
c.Interior.Color = vbYellow
End If
Next c
End If ' like "_ty"
Next hdr
End Sub

try this:
Option Compare Text
Sub ColorCellRange()
Dim c As Range
For Each c In Range("A1:E" & Range("A" & Rows.Count).End(xlUp).Row)
If c.Value Like "*Yes*" And Cells(1, c.Column).Value Like "*_ty" Then
c.Offset(0, 0).Interior.Color = vbYellow
End If
Next c
End Sub
or you can remove Option Compare Text and convert .value to low/upper case:
Sub ColorCellRange()
Dim c As Range
For Each c In Range("A1:E" & Range("A" & Rows.Count).End(xlUp).Row)
If LCase(c.Value) Like "*yes*" And _
LCase(Cells(1, c.Column).Value) Like "*_ty" Then
c.Offset(0, 0).Interior.Color = vbYellow
End If
Next c
End Sub
