Python使用win32com.client的方法示例

在网上搜索的时候，经常看到两种打开方式: dispatch和EnsureDispatch

import win32com.client as win32
xl_dis = win32.Dispatch("Excel.Application")

import win32com.client as win32
xl_ens = win32.gencache.EnsureDispatch("Excel.Application")

两种方式的差别参见：

#创建

#word
w = win32com.client.Dispatch("Word.Application")    
w = win32com.client.DispatchEx("Word.Application")#使用启动独立的进程

#excel
xlApp = win32com.client.Dispatch("Excel.Application")

#后台运行, 不显示, 不警告
w.Visible = 0;
w.DisplayAlerts = 0;

#打开新的文件

#word
doc = w.Documents.Open(FileName)
#new_doc = w.Documents.Add() #创建新的文档

#excel
xlBook = xlApp.Workbooks.Open(FileName)
#new_xlBook = xlApp.Workbooks.Add() #创建新的工作簿

#插入文字

#word
myRange = doc.Range(0, 0)
myRange.InsertBefore("hello from Python")

#excel

#使用样式
wordStyle = myRange.Select()
wordStyle.Style = constants.wdStyleHeading1

#正文文字替换
w.Selection.Find.ClearFormatting()
w.Selection.Find.Replacement.ClearFormatting()
w.Selection.Find.Execute(OldStr, False, False, False, False, False, True, 1, True, NewStr, 2)

#表格操作

#word
doc.Tables[0].Rows[0].Cells[0].Range.Text = "hello world Python"
worddoc.Tables[0].Rows.Add() #增加一行

#excel

#获取
_sheet = xlBook.Worksheets(sheet)
_sheet.Cell(row, col).Value

#设置
_sheet = xlBook.Worksheets(sheet)
_sheet.Cells(row, col).Value = values

#范围操作
_sheet = xlBook.Worksheets(sheet)
_sheet.Range(_sheet.Cell(row1, col1), _sheet.Cell(row2, col2)).Value

#添加图片

#excel
_sheet = xlBook.Worksheets(sheet)
_sheet.Shapes.AddPicture(picturename, 1, 1, Left, Top, Width, Height)

#copy 工作簿

sheets = xlBook.Worksheets
sheets(1).Copy(None, sheets(1))

#转换为html

#word
wc = win32com.client.constants
w.ActiveDocument.WebOptions.RelyOnCSS = 1
w.ActiveDocument.WebOptions.OptimizeForBrowser = 1
w.ActiveDocument.WebOptions.BrowserLevel = 0 # constants.wdBrowserLevelV4
w.ActiveDocument.WebOptions.OrganizeInFolder = 0
w.ActiveDocument.WebOptions.UseLongFileNames = 1
w.ActiveDocument.WebOptions.RelyOnVML = 0
w.ActiveDocument.WebOptions.AllowPNG = 1
w.ActiveDocument.SaveAs(FileName, FileFormat = wc.wdFormatHTML)

#打印
doc.PrintOut()

#保存

#excel
xlBook.SaveAs(FileName)#另存为
xlBook.Save()

#关闭

#word
#doc.Close()
w.Documents.Close(wc.wdDoNotSaveChanges)
w.Quit()

#excel
xlBook.Close(SaveChange = 0)
xlBook.Quit()
