python讀寫excel檔案有好幾個工具。我用過pywin32。但最近發現用直接操縱xml的方法更快，而且不依賴於平臺。excel檔案可以儲存為xml檔案，之後讀寫就變成了操作xml Element。excel 檔案的 格式還有需要了解的地方。下面程式碼是讀寫Cell的例子。

def setCell(table,row,col,value):
    row=row-1
    col=col-1
    rows=table.findall("{urn:schemas-microsoft-com:office:spreadsheet}Row")
    row1=rows[row]
    cells=row1.findall("{urn:schemas-microsoft-com:office:spreadsheet}Cell")
    #{urn:schemas-microsoft-com:office:spreadsheet}Index
    at=0
    mycells={}
    for cell in cells:#MergeAcross
        #print(cell.attrib)
        if cell.attrib.get("{urn:schemas-microsoft-com:office:spreadsheet}Index")==None:
            mycells[at]=cell
            at+=1
        else:
            at=int(cell.attrib["{urn:schemas-microsoft-com:office:spreadsheet}Index"])
            mycells[at-1]=cell
        if cell.attrib.get("{urn:schemas-microsoft-com:office:spreadsheet}MergeAcross")!=None:
