xlwings – Make Excel fly with Python!

xlwings (Open Source)

xlwings is a BSD-licensed Python library that makes it easy to call Python from Excel and vice versa:

  • Scripting: Automate/interact with Excel from Python using a syntax that is close to VBA.
  • Macros: Replace your messy VBA macros with clean and powerful Python code.
  • UDFs: Write User Defined Functions (UDFs) in Python (Windows only).

Numpy arrays and Pandas Series/DataFrames are fully supported. xlwings-powered workbooks are easy to distribute and work
on Windows and macOS.

xlwings includes all files in the xlwings package except the pro folder, i.e., the xlwings.pro subpackage.
