Now after downloading and installing openpyxl and after having this testfile in root folder lets get to the task. In case you don't know what is your root directory for python. Type in the following code at prompt.
If you want to change the current working directory you can use the command os.
For example you have a file named abc. If you want to work with excel files in Python for a Live 1 on 1 Python Openpyxl Training you may contact us live 1 on 1 interactive Openpyxl training by an expert.
Learn each and everything about how to deal with excel files in python like reading, writing, sorting, editing, making high quality graphs and charts in matplotlib.
