Pandas excel file format cannot be determined, you must specify an engine manually.

by

The error message “pandas excel file format cannot be determined, you must specify an engine manually” typically occurs when trying to read an Excel file using the pandas library without specifying the file format or engine explicitly. This error occurs because pandas needs to know the engine to use in order to determine the format of the Excel file.

To resolve this error, you need to specify the engine parameter when reading the Excel file. The available engines in pandas are “xlrd”, “openpyxl”, and “pyxlsb”. The appropriate engine to use depends on the format of your Excel file.

Here is an example of how to read an Excel file using the “xlrd” engine: 

    
      import pandas as pd
      
      df = pd.read_excel("filename.xlsx", engine="xlrd")
      print(df)

In this example, the “filename.xlsx” is the path to your Excel file. The “engine” parameter is set to “xlrd” to specify the engine to use for reading the file.

If your Excel file has the “.xlsx” extension, you can also use the “openpyxl” engine. Here is an example: 

    
      import pandas as pd
      
      df = pd.read_excel("filename.xlsx", engine="openpyxl")
      print(df)

Similarly, if your Excel file has the “.xlsb” extension, you can use the “pyxlsb” engine. Here is an example: 

    
      import pandas as pd
      
      df = pd.read_excel("filename.xlsb", engine="pyxlsb")
      print(df)

By specifying the engine parameter with the appropriate value, you can avoid the error and read the Excel file successfully using pandas.
