Unable to read xlsb file using pandas

Question

I am trying to read an xlsb file from local using pandas' read_excel but I am getting error. My code:

import pandas as pd
df3 = pd.read_excel('a.xlsb', engine = 'pyxlsb')

Error:

ValueError: Unknown engine: pyxlsb

It works fine for csv and xlsx files.

python version: 3.5.2
pandas version: 0.24.2

First install pyxlsb and run the below code.After running the code, you'll have your data stored in df1.

pip install pyxlsb

import pandas as pd
from pyxlsb import open_workbook

df=[]
with open_workbook('some.xlsb') as wb:
    with wb.get_sheet(1) as sheet:
        for row in sheet.rows():
            df.append([item.v for item in row])

df1 = pd.DataFrame(df[1:], columns=df[0])
