To solve this error, you need to install openpyxl module. In this tutorial, we will use pip to install openpyxl module. Run the following command, to install openpyxl.

If you have both python2.x and python3.x versions installed in your machine, use pip to install in python2.x and pip3 to install in python3.x.
