excel - una - Guarde cada hoja en un libro de trabajo para separar archivos CSV

concatenar varias hojas de excel en una sola

Question

¿Cómo guardo cada hoja en un libro de Excel para separar archivos CSV con una macro?

Tengo un Excel con varias hojas y estaba buscando una macro que guarde cada hoja en un CSV (comma separated file) separado CSV (comma separated file) . Excel no le permitirá guardar todas las hojas en diferentes archivos CSV .

Answer 1

@AlexDuggleby: no necesita copiar las hojas de trabajo, puede guardarlas directamente. p.ej:

Public Sub SaveWorksheetsAsCsv()
Dim WS As Excel.Worksheet
Dim SaveToDirectory As String

    SaveToDirectory = "C:/"

    For Each WS In ThisWorkbook.Worksheets
        WS.SaveAs SaveToDirectory & WS.Name, xlCSV
    Next

End Sub

El único problema potencial es que eso deja su libro de trabajo guardado como el último archivo csv. Si necesita conservar el libro de trabajo original, deberá guardarlo.

Aquí hay uno que le dará un selector visual de archivos para elegir la carpeta en la que desea guardar los archivos y también le permite elegir el delimitador CSV (yo uso pipes ''|'' porque mis campos contienen comas y no quiero tratar con comillas):

Answer 3

Basándose en la respuesta de Graham, el código adicional guarda el libro de trabajo en su ubicación original en su formato original.

Public Sub SaveWorksheetsAsCsv()

Dim WS As Excel.Worksheet
Dim SaveToDirectory As String

Dim CurrentWorkbook As String
Dim CurrentFormat As Long

 CurrentWorkbook = ThisWorkbook.FullName
 CurrentFormat = ThisWorkbook.FileFormat
'' Store current details for the workbook

      SaveToDirectory = "C:/"

      For Each WS In ThisWorkbook.Worksheets
          WS.SaveAs SaveToDirectory & WS.Name, xlCSV
      Next

 Application.DisplayAlerts = False
  ThisWorkbook.SaveAs Filename:=CurrentWorkbook, FileFormat:=CurrentFormat
 Application.DisplayAlerts = True
'' Temporarily turn alerts off to prevent the user being prompted
''  about overwriting the original file.

End Sub

Mire la respuesta de Von Pookie , todos los créditos para él / ella.

 Sub asdf()
Dim ws As Worksheet, newWb As Workbook

Application.ScreenUpdating = False
For Each ws In Sheets(Array("EID Upload", "Wages with Locals Upload", "Wages without Local Upload"))
   ws.Copy
   Set newWb = ActiveWorkbook
   With newWb
      .SaveAs ws.Name, xlCSV
      .Close (False)
   End With
Next ws
Application.ScreenUpdating = True

End Sub

Answer 5

Una pequeña modificación a la respuesta de Alex es encender y apagar el cálculo automático.

Sorprendentemente, el código no modificado funcionaba bien con VLOOKUP pero falló con OFFSET. Además, la desactivación del cálculo automático acelera el ahorro drásticamente.

Public Sub SaveAllSheetsAsCSV()
On Error GoTo Heaven

'' each sheet reference
Dim Sheet As Worksheet
'' path to output to
Dim OutputPath As String
'' name of each csv
Dim OutputFile As String

Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False

'' Save the file in current director
OutputPath = ThisWorkbook.Path


If OutputPath <> "" Then
Application.Calculation = xlCalculationManual

'' save for each sheet
For Each Sheet In Sheets

    OutputFile = OutputPath & Application.PathSeparator & Sheet.Name & ".csv"

    '' make a copy to create a new book with this sheet
    '' otherwise you will always only get the first sheet

    Sheet.Copy
    '' this copy will now become active
     ActiveWorkbook.SaveAs Filename:=OutputFile, FileFormat:=xlCSV,     CreateBackup:=False
    ActiveWorkbook.Close
Next

Application.Calculation = xlCalculationAutomatic

End If

Finally:
Application.ScreenUpdating = True
Application.DisplayAlerts = True
Application.EnableEvents = True

Exit Sub

Heaven:
MsgBox "Couldn''t save all sheets to CSV." & vbCrLf & _
        "Source: " & Err.Source & " " & vbCrLf & _
        "Number: " & Err.Number & " " & vbCrLf & _

Y aquí está mi solución debería funcionar con Excel> 2000, pero probó solo en 2007:

Private Sub SaveAllSheetsAsCSV()
On Error GoTo Heaven

'' each sheet reference
Dim Sheet As Worksheet
'' path to output to
Dim OutputPath As String
'' name of each csv
Dim OutputFile As String

Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False

'' ask the user where to save
OutputPath = InputBox("Enter a directory to save to", "Save to directory", Path)

If OutputPath <> "" Then

    '' save for each sheet
    For Each Sheet In Sheets

        OutputFile = OutputPath & "/" & Sheet.Name & ".csv"

        '' make a copy to create a new book with this sheet
        '' otherwise you will always only get the first sheet
        Sheet.Copy
        '' this copy will now become active
        ActiveWorkbook.SaveAs FileName:=OutputFile, FileFormat:=xlCSV, CreateBackup:=False
        ActiveWorkbook.Close
    Next

End If

Finally:
Application.ScreenUpdating = True
Application.DisplayAlerts = True
Application.EnableEvents = True

Exit Sub

Heaven:
MsgBox "Couldn''t save all sheets to CSV." & vbCrLf & _
        "Source: " & Err.Source & " " & vbCrLf & _
        "Number: " & Err.Number & " " & vbCrLf & _
        "Description: " & Err.Description & " " & vbCrLf

GoTo Finally
End Sub
