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 Mac.

Note: xlwings is currently in an early stage. The API might change in backward incompatible ways.
