I have two columns of data in a spreadsheet. Column A has either cells containing "X" or empty cells and Column B contains formulas. I want to use VBA to pull Column A into an array, and paste the array into Column B, making sure the "X"s copy over but the empty array elements do not.
The method I have looks at each array element and if it is an "X" then paste that 1 element, it works but its slow for large data pools. Is there a faster method?
See code below:
Option Explicit
Sub Test()
Dim array1 As Variant, i As Integer
array1 = Sheets("Sheet1").Range("A2:A8").Value
For i = 1 To UBound(array1)
If array1(i, 1) = "X" Then
Sheets("Sheet1").Cells(i + 1, 2) = array1(i, 1)
End If
Next i
End Sub
use a second array to hold the formula in B. Then iterate both arrays and replace the second with the value where needed:
Sub Test()
With Sheets("Sheet1")
Dim aArr() As Variant
aArr = .Range("A2:A8").Value
Dim bArr() As Variant
bArr = .Range("B2:B8").Formula
Dim i As Long
For i = 1 To UBound(aArr, 1)
If aArr(i, 1) = "X" Then
bArr(i, 1) = aArr(i, 1)
End If
Next i
.Range("B2:B8").Formula = bArr
End With
End Sub
It is assumed that
ThisWorkbook
, the workbook containing this code,Data Column
is adjacent to the right of the Criteria Column
, which is defined by FirstCellAddress
, Criteria
( X
) is case-sensitive ie X <> x
. The Code
Option Explicit
Sub replaceFormulasWithCriteria()
Const wsName As String = "Sheet1"
Const FirstCellAddress As String = "A2"
Const Criteria As String = "X"
' Define Criteria Column Range.
Dim rng As Range
With ThisWorkbook.Worksheets(wsName).Range(FirstCellAddress)
Set rng = .Resize(.Worksheet.Cells(.Worksheet.Rows.Count, .Column) _
.End(xlUp).Row - .Row + 1)
End With
' Write values from Criteria Column Range to Criteria Array.
Dim Crit As Variant: Crit = rng.Value
' Define Data Column Range.
Set rng = rng.Offset(, 1)
' Write formulas from Data Column Range to Data Array.
Dim Data As Variant: Data = rng.Formula
Dim i As Long
' Loop through rows of Criteria/Data Column Range.
For i = 1 To UBound(Data, 1)
' Check if Criteria is found in current row in Criteria Array.
If Crit(i, 1) = Criteria Then
' Write Criteria to current row in Data Array.
Data(i, 1) = Criteria
End If
Next i
' Write modified values from Data Array to Data Column Range.
rng.Value = Data
' or:
'rng.Formula = Data
End Sub
