Description
Problem description
When using Pandas read_excel function with an Excel file that has a column heading that is blank, Pandas will regard the column with the blank heading as the index.
Consider this example file: https://tinyurl.com/y8br2js4
Within this file, column B does not have a column heading, it is just a blank cell. The rest of the columns have names.
When running this code:
import pandas as pd
xlsx_file = './Input/Test_File.xlsx'
test_df = pd.read_excel(xlsx_file,
index_col=None,
usecols='B, C, E, F')
The resulting dataframe will use column B as the index, even though index_col=None is specified. If I add column A to usecols, the dataframe processes the file as expected.
Output of pd.show_versions()
