Working with Excel files in Python using Xlwings
Xlwings is a Python library that makes it easy to call Python from Excel and vice versa. It creates reading and writing to and from Excel using Python easily. It can also be modified to act as a Python Server for Excel to synchronously exchange data between Python and Excel. Xlwings makes automating Excel with Python easy and can be used for- generating an automatic report, creating Excel embedded functions, manipulating Excel or CSV databases etc.
The virtual environment is used to separate a project environment (libraries, environment variables etc) etc from other project and from the global environment of the same machine. This step is optional as it isn’t always necessary to create a virtual environment for a project. We will be using a python package virtualenv for this purpose.
virtualenv env .\env\scripts\activate
And the virtual environment is ready.
pip install xlwings
To start using Xlwings, there are certain basic steps which are to be done almost every time. This includes opening an Excel file, viewing the sheet available and then selecting a sheet.

Below are some examples which depict how to perform various operations using Xlwings library:
Values can be selected from an Excel sheet by specifying a cell, row, column, or area. Selecting the entire row or column is not recommended as an entire row or column in Excel is quite long, so it would result in a long list of trailing None. Selecting a range of 2D data will result in a list of lists of data.
Xlwings can be used to insert data in an Excel file similarly that it reads from an Excel file. Data can be provided as a list or a single input to a certain cell or a selection of cells.
