raise ValueError("Cannot convert {0!r} to Excel".format(value))

I have hundreds of XML files that I need to extract two values from and ouput in an Excel or CSV file. This is the code I currently have:

#grabs idRoot and typeId root values from XML files
import glob
from openpyxl import Workbook
from xml.dom import minidom import os wb = Workbook() ws = wb.active def typeIdRoot (filename): f = open(filename, encoding = "utf8") for xml in f: xmldoc = minidom.parse(f) qmd = xmldoc.getElementsByTagName("MainTag")[0] typeIdElement = qmd.getElementsByTagName("typeId")[0] root = typeIdElement.attributes["root"] global rootValue rootValue = root.value print ('rootValue =' ,rootValue,) ws.append([rootValue]) wb.save("some.xlsx") wb = Workbook() ws = wb.active def idRoot (filename): f = open(filename, encoding = "utf8") for xml in f: xmldoc = minidom.parse(f) tcd = xmldoc.getElementsByTagName("MainTag")[0] activitiesElement = tcd.getElementsByTagName("id")[0] sport = activitiesElement.attributes["root"] sportName = sport.value print ('idRoot =' ,sportName,) ws.append([idRoot]) wb.save("some.xlsx") for file in glob.glob("*.xml"): typeIdRoot (file) for file in glob.glob("*.xml"): idRoot (file) 

The first value follows a 1.11.111.1.111111.1.3 format. The second mixes letters and numbers. I believe this is the reason for the error: 

 

Traceback (most recent call last):
  File "C:\Python34\Scripts\xml\good.py", line 64, in <module> idRoot (file) File "C:\Python34\Scripts\xml\good.py", line 54, in idRoot ws.append([idRoot]) File "C:\Python34\lib\site-packages\openpyxl\worksheet\worksheet.py", line 754, in append cell = self._new_cell(col, row_idx, content) File "C:\Python34\lib\site-packages\openpyxl\worksheet\worksheet.py", line 376, in _new_cell cell = Cell(self, column, row, value) File "C:\Python34\lib\site-packages\openpyxl\cell\cell.py", line 131, in __init__ self.value = value File "C:\Python34\lib\site-packages\openpyxl\cell\cell.py", line 313, in value self._bind_value(value) File "C:\Python34\lib\site-packages\openpyxl\cell\cell.py", line 217, in _bind_value raise ValueError("Cannot convert {0} to Excel".format(value)) ValueError: Cannot convert <function idRoot at 0x037D24F8> to Excel 

I would like the result to add both values on the same row. So then I would have a new row for each file in the directory. I need to add the second value to the second row.

as such:

  Value 1                           Value 2
1.11.111.1.111111.1.3 10101011-0d10-0101-010d-0dc1010e0101

idRoot is the name of your FUNCTION. So when you write

ws.append([idRoot])

you probably mean:

ws.append([sportName])

Of course, you can write something like:

ws.append([rootValue, sportName])

providing both variables are defined with reasonable values. One last thing, you should save your file only once.
