Retrieve Column header depending on values present in an excel worksheet - excel

Question

I have two worksheets ( sheet 1 and sheet 2) . Sheet 1 has 500X500 table. I want to
- Loop through each row ( each cell )
- Identify the cells which have a value ' X' in it
- Pick the respective column header value and store it in a cell in worksheet 2
For example
AA BB CC DD EE FF GG HH
GHS X
FSJ X
FSA X
MSD
SKD
SFJ X X
SFJ
SFM X
MSF X
Is there a way of writing a macro which will pull values in the form of
GHS -> GG
FSJ->DD
.
.
SFJ->BB HH
I have tried looping algorithms but does not seem to work. Could anyone please help me as I am very new to macros.

Answer 1

Try this .. Assumed that GHS, FSJ ... in column A
Sub ColnItem()
Dim x, y, z As Integer
Dim sItem, sCol As String
Dim r As Range
z = 1
For y = 1 To 500
sItem = Cells(y, 1)
sCol = ""
For x = 2 To 500
If UCase(Cells(y, x)) = "X" Then
If Len(sCol) > 0 Then sCol = sCol & " "
sCol = sCol & ColumnName(x)
End If
Next
If Len(sCol) > 0 Then
Sheets("Sheet2").Cells(z, 1) = sItem & " -> " & sCol
z = z + 1
End If
Next
End Sub
Function ColumnName(ByVal nCol As Single) As String
Dim sC As String
Dim nC, nRest, nDivRes As Integer
sC = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
nC = Len(sC)
nRest = nCol Mod nC
nDivRes = (nCol - nRest) / nC
If nDivRes > 0 Then ColumnName = Mid(sC, nDivRes, 1)
ColumnName = ColumnName & Mid(sC, nRest, 1)
End Function

Answer 2

I have placed the values GG, etc., in separate columns of Sheet2, but the code could be modified to put all the information (for a row) in a single cell.
Sub GetColumnHeadings()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim rng1 As Range, rng2 As Range, rng As Range
Dim off As Integer
Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
Set rng1 = ws1.Range("A1").CurrentRegion
'CurrentRegion is the Range highlighted when we press Ctrl-A from A1
Set rng2 = ws2.Range("A1")
Application.ScreenUpdating = False
For Each rng In rng1
If rng.Column = 1 Then off = 0
If rng.Value = "X" Then
rng2.Value = rng.EntireRow.Cells(1, 1).Value
off = off + 1
rng2.Offset(0, off).Value = rng.EntireColumn.Cells(1, 1).Value
End If
'if we are looking at the last column of the Sheet1 data, and
'we have put something into the current row of Sheet2, move to
'the next row down (in Sheet2)
If rng.Column = rng1.Column And rng2.Value <> "" Then
Set rng2 = rng2.Offset(1, 0)
End If
Next rng
Application.ScreenUpdating = True
Set rng = Nothing
Set rng2 = Nothing
Set rng1 = Nothing
Set ws2 = Nothing
Set ws1 = Nothing
End Sub
I've also based in on the spreadsheet sample from the original post, where AA appears to be in cell A1.
