Python using pandas to convert xlsx to csv file. How to delete index column?

Question

I am using the following code to convert .xlsx files into .csv files.

import pandas as pd data_xls = pd.read_excel('excelfile.xlsx', 'Sheet2', index_col=None) data_xls.to_csv('csvfile.csv', encoding='utf-8') 

The code is working, however I am getting an index column with the cell numbers which I do not want. Is there anyway to not include or remove that index column?

File output

 Unnamed  Data     0   0.99319613     1   0.99319613     2   0.99319613     3   0.99319613     4   0.99319613     5   0.99319613 

Answer 1

As noted in the docs for pandas.DataFrame.to_csv(), simply pass index=False as a keyword argument, to exclude row names.

data_xls.to_csv('csvfile.csv', encoding='utf-8', index=False) 

Answer 2

Inspired by miradulo and fix a number conversion problem:

import pandas as pd data_xls = pd.read_excel('excelfile.xlsx', 'Sheet2', dtype=str, index_col=None) data_xls.to_csv('csvfile.csv', encoding='utf-8', index=False) 

Can drop 'Sheet2' if there is one sheet. dtype=str to avoid number conversion.
