openpyxl - load_workbook giving value error for string literal -

so writing simple test code in python, cant seem load workbook read , write into. workbook trying open has lot of data , linked access database. using python 2.7.

here code:

from openpyxl import workbook openpyxl import load_workbook print("here1") wb = load_workbook("z:\\pythonfiles\\testexcel2.xlsx") print("here2") ws1 = wb.get_sheet_by_name("output model") import datetime print("here3")  ws1.cell(row=3, column=9).value="somevalue2"  wb.save("z:\\pythonfiles\\testexcel2.xlsx") 

now here error:

here1  traceback (most recent call last): file "z:\pythonfiles\test.py", line 4, in <module> wb = load_workbook("z:\\pythonfiles\\testexcel2.xlsx")  file "c:\python27\openpyxl\reader\excel.py", line 233, in load_workbook parser.parse()  file "c:\python27\openpyxl\reader\worksheet.py", line 104, in parse dispatcher[tag_name](element)  file "c:\python27\openpyxl\reader\worksheet.py", line 235, in parse_row_dimensions self.parse_cell(cell) file "c:\python27\openpyxl\reader\worksheet.py", line 191, in parse_cell value = _cast_number(value)  file "c:\python27\openpyxl\reader\worksheet.py", line 55, in _cast_number return int(value)  valueerror: invalid literal int() base 10: '1e-3'
