Export a Python List to Excel

问题:

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()

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)

You are missing both the cell row number in Range and need to increment cell row after each iteration of the loop.

sh.Range("A1").Offset(0,x).Value = i

This change should work.

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)
        x=0
        for i in EventTableRFT:
            sh.Range("A1").Offset(0,x).Value = i #You need to increment the cell row
            x+=1
        sh.Cells(i+2,1).Value = "End of the List!"

xprt = XcelExport()
xprt.excel()
