2、第二步：按快捷键alt+F11打开vba编辑器，有的需要加Fn键；
3、第三步：点击插入——模块，如图：
4、第四步：输入下面代码：Option ExplicitSub SplitEveryFivePagesAsDocuments()Dim oSrcDoc As Document, oNewDoc As DocumentDim strSrcName As String, strNewName As StringDim oRange As RangeDim nIndex As Integer, nSubIndex As Integer, nTotalPages As Integer, nBound As IntegerDim fso As ObjectConst nSteps = 1 ' 修改这里控制每隔几页分割一次Set fso = CreateObject("Scripting.FileSystemObject")Set oSrcDoc = ActiveDocumentSet oRange = oSrcDoc.ContentnTotalPages = ActiveDocument.Content.Information(wdNumberOfPagesInDocument)oRange.Collapse wdCollapseStartoRange.SelectFor nIndex = 1 To nTotalPages Step nStepsSet oNewDoc = Documents.AddIf nIndex + nSteps > nTotalPages ThennBound = nTotalPagesElsenBound = nIndex + nSteps - 1End IfFor nSubIndex = nIndex To nBoundoSrcDoc.ActivateoSrcDoc.Bookmarks("\page").Range.CopyoSrcDoc.Windows(1).ActivateApplication.Browser.Target = wdBrowsePageApplication.Browser.NextoNewDoc.ActivateoNewDoc.Windows(1).Selection.PasteNext nSubIndexstrSrcName = oSrcDoc.FullNamestrNewName = fso.BuildPath(fso.GetParentFolderName(strSrcName), _fso.GetBaseName(strSrcName) & "_" & (nIndex \ nSteps + 1) & "." & fso.GetExtensionName(strSrcName))oNewDoc.SaveAs strNewNameoNewDoc.Close FalseNext nIndexSet oNewDoc = NothingSet oRange = NothingSet oSrcDoc = NothingSet fso = NothingMsgBox "结束！"End Sub
5、第五步：按F5或者按圈出的按钮执行，看到结束即可；
