  if(activeCell.getColumn() == 1 && activeCell.getRow() > 1 && ss.getSheetName() == tabValidation){
    activeCell.offset(0, 1).clearContent().clearDataValidations();
    var makes = datass.getRange(1, 1, 1, datass.getLastColumn()).getValues();
    var makeIndex = makes[0].indexOf(activeCell.getValue()) + 1;
    if(makeIndex != 0){
        var validationRange = datass.getRange(3, makeIndex, datass.getLastRow());

Excel VBA – Set Column Width Exactly the Same in Other Workbooks – How to Code Examples

This Excel macro is useful if you have one or more Excel files where you want to set the column sizes exactly the same as the other workbook.

This script will take the current active (selected) workbook (Excel File) as a reference, get all the column widths from the active sheet (selected tab) and apply exactly the same widths to the active sheets (selected tabs) on all the other open workbooks (Excel files).

This VBA code will only affect active sheets.

Don’t forget to like and share if you found the code useful!


Sub MatchColumWidth()
    'Set column widths of all the other open workbooks to the same size as the current one
    'This script will only affect active sheets

    abookm = ActiveWorkbook.Name
    For Each wb In Application.Workbooks
        If wb.Name <> abookm Then
            For Each c In Workbooks(abookm).ActiveSheet.Columns
                wb.ActiveSheet.Columns(c.Column).ColumnWidth = c.ColumnWidth
            Next c

VBA – Run a PowerPoint Macro using Excel VBA – How to Code Examples

Below is a demonstration of using PowerPoint.Application to open a PowerPoint file and then run a macro that is stored within the PowerPoint file.

  1. Make sure you modify “fullpath\p1.pptm” and point it to the full path-filename to your PowerPoint file.
  2. Modify the macro name. Macro name must be full macro name with file, module and macro name in your PowerPoint file in order for this script to work. Use the following format “p1.pptm!”
Sub RunPowerPointMacro()

Dim objPP As Object
Dim objPPFile As Object

Set objPP = CreateObject("PowerPoint.Application")
objPP.Visible = True

Set objPPFile = objPP.Presentations.Open("fullpath\p1.pptm")

Application.EnableEvents = False

objPP.Run "p1.pptm!"

Application.EnableEvents = True


Set objPPFile = Nothing
Set objPP = Nothing

VBA – Display a File Open Dialog and Open the File – Excel functions

Below is a demonstration of using Application.FileDialog to give the user an option to select a file and then open it. The code is well commented and should be self explanatory.

The full file path will be stored in fullpath variable, which is used later in the code to open the file after making sure there was an Excel file selected.

Sub FileOpenDialogBox()

'Display a Dialog Box that allows to select a single file.
'The path for the file picked will be stored in fullpath variable
  With Application.FileDialog(msoFileDialogFilePicker)
        'Makes sure the user can select only one file
        .AllowMultiSelect = False
        'Filter to just the following types of files to narrow down selection options
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        'Show the dialog box
        'Store in fullpath variable
        fullpath = .SelectedItems.Item(1)
    End With
    'It's a good idea to still check if the file type selected is accurate.
    'Quit the procedure if the user didn't select the type of file we need.
    If InStr(fullpath, ".xls") = 0 Then
        Exit Sub
    End If

    'Open the file selected by the user
    Workbooks.Open fullpath

End Sub
