Error in converting txt to xlsx using python

问题:

My code is following.

import csv import openpyxl  import sys   def convert(input_path, output_path):     """     Read a csv file (with no quoting), and save its contents in an excel file.     """     wb = openpyxl.Workbook()     ws = wb.worksheets[0]      with open(input_path) as f:         reader = csv.reader(f, delimiter='\t', quoting=csv.QUOTE_NONE)         for row_index, row in enumerate(reader):             for col_index, value in enumerate(row):                 ws.cell(row=row_index, column=col_index).value = value      wb.save(output_path)   def main():     try:         input_path, output_path = sys.argv[1:]     except ValueError:         print 'Usage: python %s input_path output_path' % (sys.argv[0],)     else:         convert(input_path, output_path)   if __name__ == '__main__':     main() 

But I got this error.

Traceback (most recent call last):    File "txt2xlsx.py", line 33, in <module>      main()    File "txt2xlsx.py", line 29, in main      convert(input_path, output_path)    File "txt2xlsx.py", line 18, in convert      ws.cell(row=row_index, column=col_index).value = value    File "C:\python27\lib\site-packages\openpyxl\worksheet\worksheet.py", line 350, in cell      column = get_column_letter(column)    File "C:\python27\lib\site-packages\openpyxl\utils\__init__.py", line 100, in get_column_letter      raise ValueError("Invalid column index {0}".format(idx))  ValueError: Invalid column index 0  

I think I have installed openpyxl correctly.

And I remember I was using this program without any problem before. I recently bought a new computer so maybe this is a PC configuration issue.. But I can't figure out.

回答1:

Seems like you are using openpyxl 2.0.0 + ,according to changelog for Openpyxl 2.0.0 -

Cells are referenced with 1-indexing: A1 == cell(row=1, column=1)

The rows and columns index start at 1. So you should make your enumerate() function start at 1 as well. Example -

    for row_index, row in enumerate(reader, 1):         for col_index, value in enumerate(row, 1):             ws.cell(row=row_index, column=col_index).value = value 

Your particular code would work in openpyxl version less than 2.0.0 , it fails because of the above mentioned change in version 2.0.0 .
