Excel VBA – find out the position of your last row, column & column name…

This is a very useful function to me, it helps to find out the position of the last row and column in your worksheet, and will also get the column name for calculation and automation.  It is also hard to find out and fix the boundary in a worksheet when you are performing automatic calculation and move.

You can refer to my previous “User defined type”, to create your own variable first, so that this function will work properly.

Function FindLastRowColumn() As RowColumn

Dim infoRowColumn As RowColumn
Dim iCol As Integer
Dim iRow As Long
Dim lastColumn As Integer
Dim lastRow As Long
Dim MBox As Integer

iCol = ActiveSheet.UsedRange.Column – 1 + ActiveSheet.UsedRange.Columns.Count
lastColumn = iCol

iRow = ActiveSheet.UsedRange.Row – 1 + ActiveSheet.UsedRange.Rows.Count
lastRow = iRow

ColumnName = ConvertToLetter(lastColumn)
‘MBox = MsgBox(“Column: ” & LastColumn & “(” & ColumnName & “)” & vbCrLf & “Row: ” & LastRow, vbOKOnly)

infoRowColumn.xRow = lastRow
infoRowColumn.xColumn = lastColumn
infoRowColumn.xColumnName = ColumnName

FindLastRowColumn = infoRowColumn

End Function

Excel VBA – Check if your worksheet exists…

This is a function to check if the worksheet you are looking or working exists.

Function IsWorksheetExist(ByVal WSName As String) As Boolean

Dim CheckWS As Worksheet

For Each CheckWS In ActiveWorkbook.Worksheets
If CheckWS.Name = WSName Then IsWorksheetExist = True
Next CheckWS

End Function

Excel VBA – delete all blank columns without any content

This is a function to identify when the column(s) doesn’t have any content in each cell, then delete that entire column(s).  It is a amazing function to clean up your spreadsheets before modifying your data.

Function DeleteBlankColumns()
Dim Col As Long, ColCnt As Long, rng As Range

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

On Error GoTo Exits:

If Selection.Columns.Count > 1 Then
Set rng = Selection
Else
Set rng = Range(Columns(1), Columns(ActiveSheet.Cells.SpecialCells(xlCellTypeLastCell).Column()))
End If
ColCnt = 0
For Col = rng.Columns.Count To 1 Step -1
If Application.WorksheetFunction.CountA(rng.Columns(Col).EntireColumn) = 0 Then
rng.Columns(Col).EntireColumn.Delete
ColCnt = ColCnt + 1
End If
Next Col

Exits:
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic

End Function

Excel VBA – delete all blank rows without any content

This is a function to identify when the row(s) doesn’t have any content in each cell, then delete that entire row(s).  It is a amazing function to clean up your spreadsheets before modifying your data.

Function DeleteBlankRows()
Dim Rw As Long, RwCnt As Long, rng As Range

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

On Error GoTo Exits:

If Selection.Rows.Count > 1 Then
Set rng = Selection
Else
Set rng = Range(Rows(1), Rows(ActiveSheet.Cells.SpecialCells(xlCellTypeLastCell).Row()))
End If
RwCnt = 0
For Rw = rng.Rows.Count To 1 Step -1
If Application.WorksheetFunction.CountA(rng.Rows(Rw).EntireRow) = 0 Then
rng.Rows(Rw).EntireRow.Delete
RwCnt = RwCnt + 1
End If
Next Rw

Exits:
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic

End Function

Excel VBA – delete a single column…

This is a function to delete a specific column based on the Column letter and Row number.

e.g. DeleteSingleColumn(“A”, 1), then Column A will be completely deleted

Function DeleteSingleColumn(ByVal validColumn As String, ByVal StartRow As Long)

Dim i As Long
Dim DelString As String

DelString = validColumn & StartRow

Range(DelString).EntireColumn.Delete

End Function

Excel VBA – check if file or directory exists?

This is a function to verify if the desired file or directory exist, it is also important to get the status before any file operation being performed.

If the file or directory exists, it will return TRUE, otherwise, will return FALSE.

Function FileOrDirExists(ByVal PathName As String) As Boolean
‘Macro Purpose: Function returns TRUE if the specified file
     ‘               or folder exists, false if not.
     ‘PathName     : Supports Windows mapped drives or UNC
     ‘             : Supports Macintosh paths
     ‘File usage   : Provide full file path and extension
     ‘Folder usage : Provide full folder path
     ‘               Accepts with/without trailing “\” (Windows)
     ‘               Accepts with/without trailing “:” (Macintosh)

Dim iTemp As Integer

    ‘Ignore errors to allow for error evaluation
    On Error Resume Next
iTemp = GetAttr(PathName)

  ‘Check if error exists and set response appropriately
Select Case Err.Number
Case Is = 0
FileOrDirExists = True
   Case Else
FileOrDirExists = False
  End Select

   ‘Resume error checking
On Error GoTo 0
End Function

Excel VBA – Check if workbook exists…

This is a function to verify if your workbook exists in the defined location, so that before you can open your workbook, VBA codes can open your desired workbook properly.

It will return “TRUE” if the workbook is located in the desired location.

It will return “FALSE” if the workbook doesn’t exist in the desired location.

Function DoesWorkBookExist(ByVal wbPath As String, ByVal WBName As String) As Boolean

Dim i As Integer
Dim FileCheck As String

FileCheck = wbPath & “\” & WBName

If Dir(FileCheck) <> “” Then
‘MsgBox (“Workbook – ” & wbName & ” exists”)
DoesWorkBookExist = True
Else
‘MsgBox (“Workbook – ” & wbName & ” doesn’t exist”)
DoesWorkBookExist = False
End If

End Function

Excel VBA – Check if your workbook exist or not?

Before opening your workbook, you will need to verify if the workbook exists or not, so that it won’t return error or the VBA will stop improperly.

If the workbook exists, it will return “TRUE“.

If the workbook doesn’t exist, it will return “FALSE“.

Function DoesWorkBookExist(ByVal wbPath As String, ByVal WBName As String) As Boolean

Dim i As Integer
Dim FileCheck As String

FileCheck = wbPath & “\” & WBName

If Dir(FileCheck) <> “” Then
‘MsgBox (“Workbook – ” & wbName & ” exists”)
DoesWorkBookExist = True
Else
‘MsgBox (“Workbook – ” & wbName & ” doesn’t exist”)
DoesWorkBookExist = False
End If

End Function

Excel VBA – Text to Columns feature

It is a subroutine and can be executed directly via the Macro list.  The function is to modify delimited text into separate columns, so you can manipulate data better and easily.

objRange1 is the definition of the range within a worksheet, you can specify.

Destination:=Range(“A3”) is the location where the output will be appeared, you can specify.

Sub Split2Col()

Dim objRange1 As Range

‘Set up the ranges
Set objRange1 = Range(“A1:A20”)

‘Do the first parse
objRange1.TextToColumns _
Destination:=Range(“A3”), _
DataType:=xlDelimited, _
Tab:=False, _
Semicolon:=False, _
Comma:=False, _
Space:=False, _
Other:=True, _
OtherChar:=”|”

End Sub

Excel VBA – How to create User-Defined Type…

You can create your own User-Defined Type in VBA, which you can group the common variables in this type “RowColumn”.

In this “RowColumn” variable, it will contain Row, Column Number, Column Letter and the Address (range reference for the specified range, this can speed up in calculation).

Now you will be able to define your own “RowColumn” as variable,

e.g. Dim infoRowColumn As RowColumn

Option Explicit

Public Type RowColumn
xRow As Long
xColumn As Integer
xColumnName As String
xAddress As String
End Type
