reading from and writing to excel files in python can be efficiently handled using libraries such as *pandas* and **openpyxl**. this tutorial will guide you through the steps to read from and write to excel files using these libraries.

prerequisites

ensure you have the following libraries installed:



reading excel files

pandas provides a simple function called `read_excel()` to read data from an excel file. here's how to use it:

example: reading an excel file



writing to excel files

reading multiple sheets

if your excel file has multiple sheets and you want to read them all, you can do so by passing `sheet_name=none` to `read_excel()`, which returns a dictionary of dataframes.

example: reading multiple sheets



writing multiple dataframes to different sheets

you can write multiple dataframes to different sheets in the same excel file using the `excelwriter` context manager.
