Export a Python List to Excel


I am trying to export a list to excel via the Win32COM client whihc i have imported at the header. The object i created is coded as below, but I cant seem to get it to export each value to its own row in the spreadsheet. If I can get a good pointer (other than give up python!! :D), I would appreciate it.

class XcelExport():
    def excel(self):
        app = 'Excel'
        xl = win32.gencache.EnsureDispatch('%s.Application' % app)
        ss = xl.Workbooks.Open(r'C:\MyFile.xls')
        sh = ss.ActiveSheet
        xl.Visible = True
        sleep(.1)  
        sh.Cells(1,1).Value = 'Export-to-%s : Items' % app
        sleep(.1)
        for i in EventTableRFT:
            sh.Range("A").Value = i 
        sh.Cells(i+2,1).Value = "End of the List!"

xprt = XcelExport()
xprt.excel()

Solution

  • Since you seemed to like my answer/comment, here's an answer proper:

    Python Excel has just about everything you'd ever need. If you want something more integrated but seems limited, there is IronSpread. XLRD and XLWT are great packages, but they don't support *.xlsx files. IronSpread is Windows only and only support '07 and '10 versions of Excel. Each has it's caveats. In the end, you can use both (edit as *.xlsx, then save as to *.xls (I had someone who had speed issues with large *.xls files, but my script wrote 200mb of text from that thing in like 1 minute.)).

    Oh, and I would definitely read (skim) the documentation for interesting features such as getting the cell types etc of xlrd/xlwt. It's worth it, if only because it's short and will save you the learning curve of experimenting.

    Super short example of xlwt:

    import xlwt
    from tempfile import TemporaryFile
    book = xlwt.Workbook()
    sheet1 = book.add_sheet('sheet1')
    
    supersecretdata = [34,123,4,1234,12,34,12,41,234,123,4,123,1,45123,5,43,61,3,56]
    
    for i,e in enumerate(supersecretdata):
        sheet1.write(i,1,e)
    
    name = "random.xls"
    book.save(name)
    book.save(TemporaryFile())
    

    Super short example of xlrd:

    import xlrd
    from xlrd import open_workbook
    book = open_workbook('random.xls')
    sheet1 = book.sheet_by_index(0)
    data = []
    
    for i in xrange(sheet1.nrows):
        data.append(sheet1.cell(i,1).value)
