I have a macro in a workbook that saves selected sheets in a workbook as separate csv files. I thought this was working fine but I now seem to be getting the error message below, I'm not sure if I've inadvertently changed something, as I was trying to write a separate macro to run this one from another workbook. Error message:
Run time error '1004' Cannot access read-only document ' Activity.csv'
Public Sub SaveWorksheetsAsCsv3()
'save workbook before continuing
ActiveWorkbook.Save
Application.DisplayAlerts = False
'save each sheet as csv
 Dim WB As Workbook
 Dim WS As Worksheet
 Dim FolderPath As String
 Dim FileName As String
'folder path for saving
 FolderPath = Range("B3").Value
 
'loop through all sheets
 For Each WS In Worksheets
 
'ignore these sheets
 If WS.Name <> "Control" And WS.Name <> "Summary" Then
    
'copy current sheet
     WS.Copy
     Set WB = ActiveWorkbook
     
'save as csv file
     FileName = WS.Name
     WB.SaveAs FileName:=FolderPath & "\" & FileName, FileFormat:=xlCSV, CreateBackup:=False
     Application.DisplayAlerts = True
     WB.Close
     Application.DisplayAlerts = False
    End If
 Next WS
End Sub
