How to Fix "xlrd.biffh.XLRDError: Excel xlsx file; not supported" Error in Pandas?
If you encounter the "xlrd.biffh.XLRDError: Excel xlsx file; not supported" error in Pandas when trying to read an Excel file, it means that the xlrd library being used by Pandas is not able to read the .xlsx file format. This error usually occurs when you are using an old version of xlrd that does not support the newer .xlsx file format.
To fix this error, you need to either upgrade your xlrd library or install an alternative library that supports the .xlsx file format. One such library is openpyxl, which can be installed using pip:
pip install openpyxl
Once you have installed openpyxl, you can use it instead of xlrd to read .xlsx files by specifying the engine parameter when using the read_excel() function:
import pandas as pd
# read .xlsx file using openpyxl engine
df = pd.read_excel('filename.xlsx', engine='openpyxl')
By using the openpyxl engine, you should be able to read the .xlsx file without encountering the "not supported" error.
