Using the Current Month in a Folder Path in VBA Code - excel

Question

When I run this code I get an error message
"compile error: named argument not found".
Sub SavetoCurrentMonth()
Application.DisplayAlerts = False
' Check for month folder and create if needed
If Len(Dir("C:\Users\OsmonBek\Documents\macros test\" & Format(Month(Date), "P00-") & Format(Date, "mmmm"), vbDirectory)) = 0 Then
MkDir "C:\Users\OsmonBek\Documents\macros test\" & Format(Month(Date), "P00-") & Format(Date, "mmmm")
End If
' Save File
ActiveWorkbook.ExportAsFixedFormat Filename:= _
"C:\Users\OsmonBek\Documents\macros test\" & MonthName(Month(Date), False) & "\" & Format(Date, "mm.dd.yy") & ".xlsx" _
, FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
Application.DisplayAlerts = True
' Popup Message
MsgBox "File Saved As:" & vbNewLine & "C:\Users\OsmonBek\Documents\macros test\" & MonthName(Month(Date), False) & "\" & Format(Date, "mm.dd.yy") & ".xlsx"
End Sub

Answer 1

The error was telling you that ExportAsFixedFormat doesn't have a parameter called FileFormat.
I'd use something like this function to return the name of the folder for the current month (creating the folder if it doesn't already exist) like c:\P2022_04\.
Function getMonthFolderPath() As String
'creates/returns folder name for current month, like: c:\P2022_04\
Const basePath = "c:\", prefix = "P"
Dim path As String
path = basePath & prefix & Format(Date, "yyyy_mm")
If Dir(path, vbDirectory) = "" Then MkDir path
getMonthFolderPath = path & "\"
End Function
I added the year since (I assume) you don't all April's in the same folder.
Here's a variation that will (if needed) create a year folder with a month subfolder, and return that path:
Function getMonthFolderPath() As String
Dim path As String
path = "c:\"
path = path & Year(Date)
If Dir(path, vbDirectory) = "" Then MkDir path
path = path & "\" & Format(Date, "mm")
If Dir(path, vbDirectory) = "" Then MkDir path
getMonthFolderPath = path & "\"
End Function
Either variation could be used to save the current file, like this:
Sub saveDemo()
'save this workbook like: C:\2022\04\2022-04-08.xlsm
Dim fName As String
fName = getMonthFolderPath & Format(Date, "yyyy-mm-dd") & ".xlsm"
Application.DisplayAlerts = False 'ignore overwrite warning
ThisWorkbook.SaveAs fName, xlOpenXMLWorkbookMacroEnabled
Application.DisplayAlerts = True
End Sub
