How to convert xml file to xlsx format in python?

Question

Is it possible to automatically convert xml file into excel xlsx format in pyton to use it with openpyxl module?

Answer 1

I've had to do this before. The main idea is to use the xlrd module to open and parse a xls file and write the content to a xlsx file using the openpyxl module.
Here's my code. Attention! It cannot handle complex xls files, you should add you own parsing logic if you are going to use it.
import xlrd
from openpyxl.workbook import Workbook
from openpyxl.reader.excel import load_workbook, InvalidFileException
def open_xls_as_xlsx(filename):
# first open using xlrd
book = xlrd.open_workbook(filename)
index = 0
nrows, ncols = 0, 0
while nrows * ncols == 0:
sheet = book.sheet_by_index(index)
nrows = sheet.nrows
ncols = sheet.ncols
index += 1
# prepare a xlsx sheet
book1 = Workbook()
sheet1 = book1.get_active_sheet()
for row in xrange(0, nrows):
for col in xrange(0, ncols):
sheet1.cell(row=row, column=col).value = sheet.cell_value(row, col)
return book1
