The applications you build with MS Excel is called Visual Basic for Applications, or simply VBA. Why? Because there is built-in Visual Basic Editor in Microsoft Excel, and you can use it to customize and extend capabilities of MS Excel. You skip the last parameter because its an optional parameter.A lot of people might not realize that they can actually learn the fundamentals of Visual Basic programming without having a copy of Visual Basic professional. You would call this UDF with any of the following function calls. If IsNumeric(padding) And IsNumeric(cell) Then ' Check if you've got adequate values to proceed. ' Define and assign a default value, which must be a string data type. LPAD = String(padding, character_default) + cell LPAD = String(padding, number_default) + cell If IsNumeric(padding) And IsNumeric(cell) Then If IsNumeric(character) Then Number_default = '0' ' Check if you've got adequate values to proceed. Dim character_default As String * 1Д¬haracter_default = ' ' Dim number_default As String * 1

The equivalent function in Excel is:ДЇunction LPAD(padding AS Variant, character AS String, cell As String) ThatвЂ™s because some behaviors are implicitly provided. The formula for a number is different than it would be natively in Excel.

ReturnString = Application.Rept(' ', offset - Len(cell)) + cell ReturnString = Application.Rept('0', offset - Len(Application.Text(cell, padNumberWith))) + CStr(cell) ' Convert to string when numeric, use padWith text value when not null and whitespace if null. If IsNumeric(cell) And IsNumeric(padWith) Then ' Assign default padding value when cell is a number. If IsNumeric(offset) And Len(cell) > offset Then ' Ensure size is at least the length of the cell and padding value. ' This allows you to see the offset value when it is provided as a number.

' Dynamically assign the offset for the optional offset variable. MsgBox ('Offset should not be a non-numeric value of !') ' This means the function is called incorrectly but suppresses a #VALUE! error. ' Reports a meaningful error when a non-numeric offset parameter is provided as the offset call parameter. ' The function takes any input as a cell and manages numbers different than strings. ReturnString = Application.Rept( ' ', offset - Len(cell)) + cell

ReturnString = Application.Rept(whiteSpace, offset - Len(cell)) + cell ReturnString = Application.Rept(padWith, offset - Len(cell)) + cell ReturnString = Application.Rept( '0', offset - Len(Application.Text(cell, padNumberWith))) + CStr(cell) If IsNumeric(cell) And IsNumeric(padWith) ThenД®nd If ' Convert to string when numeric, use padWith text value when not null and whitespace if null. If IsNumeric(offset) And Len(cell) > offset ThenД®nd If ' Assign default padding value when cell is a number. WhiteSpace = ' ' ' Ensure size is at least the length of the cell and padding value. ' MsgBox ('offset is ') End If ' Assign default value. ElseIf offset = 0 ThenД®lse ' This allows you to see the offset value when it is provided as a number. MsgBox ( 'Offset should not be a non-numeric value of !') If Not IsNumeric(offset) Then ' This means the function is called incorrectly but suppresses a #VALUE! error. Dim returnString As String Dim whiteSpace As String * 1
