Excel Macro for creating new worksheets - vba

Question

I am trying to loop through some columns in a row and create new worksheets with the name of the value of the current column/row that I am in.
Sub test()
Range("R5").Select
Do Until IsEmpty(ActiveCell)
Sheets.Add.Name = ActiveCell.Value
ActiveCell.Offset(0, 1).Select
Loop
End Sub
This code creates the first one correctly starting at R5 but then it appears that the macro switches to that worksheet and doesn't complete the task.

Answer 1

The Sheets.Add automatically moves your selection to the newly created sheet (just like if you insert a new sheet by hand). In consequence the Offset is based on cell A1 of the new sheet which now has become your selection - you select an empty cell (as the sheet is empty) and the loop terminates.
Sub test()
Dim MyNames As Range, MyNewSheet As Range
Set MyNames = Range("R5").CurrentRegion ' load contigeous range into variable
For Each MyNewSheet In MyNames.Cells ' loop through cell children of range variable
Sheets.Add.Name = MyNewSheet.Value
Next MyNewSheet
MyNames.Worksheet.Select ' move selection to original sheet
End Sub
This will work better .... you assign the list of names to an object variable of type Range and work this off in a For Each loop. After you finish you put your Selection back to where you came from.

Answer 2

Sheets.Add will automatically make your new sheet the active sheet. Your best bet is to declare variables to your objects (this is always best practice) and reference them. See like I've done below:
Sub test()
Dim wks As Worksheet
Set wks = Sheets("sheet1")
With wks
Dim rng As Range
Set rng = .Range("R5")
Do Until IsEmpty(rng)
Sheets.Add.Name = rng.Value
Set rng = rng.Offset(0, 1)
Loop
End With
End Sub

Answer 3

Error handling should always be used when naming sheets from a list to handle
invalid characters in sheet names
sheet names that are too long
duplicate sheet names
Pls change Sheets("Title") to match the sheet name (or position) of your title sheet
The code below uses a variant array rather than a range for the sheet name for performance reasons, although turning off ScreenUpdating is likely to make the biggest difference to the user
Sub SheetAdd()
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Dim strError As String
Dim vArr()
Dim lngCnt As Long
Dim lngCalc As Long
Set ws1 = Sheets("Title")
vArr = ws1.Range(ws1.[r5], ws1.[r5].End(xltoRight))
If UBound(vArr) = Rows.Count - 5 Then
MsgBox "sheet range for titles appears to be empty"
Exit Sub
End If
With Application
.ScreenUpdating = False
.EnableEvents = False
lngCalc = .Calculation
End With
For lngCnt = 1 To UBound(vArr)
Set ws2 = Sheets.Add
On Error Resume Next
ws2.Name = vArr(lngCnt, 1)
If Err.Number <> 0 Then strError = strError & vArr(lngCnt, 1) & vbNewLine
On Error GoTo 0
Next lngCnt
With Application
.ScreenUpdating = True
.EnableEvents = True
.Calculation = lngCalc
End With
If Len(strError) > 0 Then MsgBox strError, vbCritical, "These potential sheet names were invalid"
End Sub

Answer 4

This is probably the simplest. No error-handling, just a one-time code to create sheets
Sub test()
Workbooks("Book1").Sheets("Sheet1").Range("A1").Activate
Do Until IsEmpty(ActiveCell)
Sheets.Add.Name = ActiveCell.Value
Workbooks("Book1").Sheets("Sheet1").Select
ActiveCell.Offset(0, 1).Select
Loop
End Sub
