Cannot read Excel file from World Bank
*Created originally on Bitbucket by [xpetrovs (Jonáš Petrovský)](https://bitbucket.org/%7B5779a0bc-9c8f-47f8-8d4c-d5a59702c16c%7D/)* Hello, I need to read an Excel file exported from World Bank database (http://databank.worldbank.org/data/reports.aspx?source=doing-business). Unfortunately opening the file (openpyxl.load_workbook) does not work - there is an exception: ``` #!python AttributeError: 'NoneType' object has no attribute 'upper' ``` I found this SO question (http://stackoverflow.com/questions/34387995/openpyxl-nonetype-object-has-no-attribute-upper), but there is no answer, just that it might be a bug. I'm using version 2.3.3. I'm enclosing a small file which also triggers the problem. Please help, thanks :). **Traceback** ``` #!python Traceback (most recent call last): File "C:/X/test.py", line 8, in <module> ip = IndicatorsProcessor(file_paths) File "C:\X\IndicatorsProcessor.py", line 16, in __init__ self.world_bank_workbook = openpyxl.load_workbook(filename=in_bank) File "C:\Python27\lib\site-packages\openpyxl\reader\excel.py", line 234, in load_workbook parser.parse() File "C:\Python27\lib\site-packages\openpyxl\reader\worksheet.py", line 106, in parse dispatcher[tag_name](element) File "C:\Python27\lib\site-packages\openpyxl\reader\worksheet.py", line 243, in parse_row_dimensions self.parse_cell(cell) File "C:\Python27\lib\site-packages\openpyxl\reader\worksheet.py", line 182, in parse_cell row, column = coordinate_to_tuple(coordinate) File "C:\Python27\lib\site-packages\openpyxl\utils\__init__.py", line 162, in coordinate_to_tuple col, row = coordinate_from_string(coordinate) File "C:\Python27\lib\site-packages\openpyxl\utils\__init__.py", line 39, in coordinate_from_string match = COORD_RE.match(coord_string.upper()) AttributeError: 'NoneType' object has no attribute 'upper' ``` *Attachments:* [small_data.xlsx](/uploads/eb73d3b1cf831e684b6f01ccda31c28b/small_data.xlsx)
