xlsxwriter

XlsxWriter is a Python module that allows you to create and manipulate Microsoft Excel files (in the .xlsx format). It is a popular library for working with Excel files in Python and provides a high level of control over the formatting and content of the resulting Excel workbooks.

Here’s a basic example of how to use XlsxWriter to create a simple Excel spreadsheet:

import xlsxwriter

# Create a new Excel workbook and add a worksheet.
workbook = xlsxwriter.Workbook('example.xlsx')
worksheet = workbook.add_worksheet()

# Write some data to the worksheet.
worksheet.write('A1', 'Hello')
worksheet.write('A2', 'World')

# Close the workbook to save it.
workbook.close()

In this example:

1. You import the xlsxwriter module.
2. Create a new Excel workbook using xlsxwriter.Workbook('example.xlsx'), where 'example.xlsx' is the name of the Excel file you want to create.
3. Add a worksheet to the workbook using workbook.add_worksheet().
4. Write data to the worksheet using worksheet.write().
5. Finally, close the workbook using workbook.close() to save the changes.

XlsxWriter provides many additional features and options for formatting cells, adding charts, images, and more. It’s a versatile library for creating Excel files in Python.

Here are some common tasks you can accomplish with XlsxWriter:
