Chapter 4: Getting Started with PyXLL

To incorporate Python into Excel using PyXLL, follow these steps:

Step 1: Installation

Start by installing PyXLL and configuring your environment. Use the following command:

pip install pyxll

pyxll install

Step 2: Create Your First Python Function

Develop a new Python module and define your function, using the @xl_func decorator to connect it to Excel. Here's an example:

from pyxll import xl_func

@xl_func

def hello(name):

return "Hello, %s" % name

Step 3: Configuration

Modify the pyxll.cfg file to include your module in the loading list and set the directory in the pythonpath configuration:

[PYXLL]

modules = mymodule

[PYTHON]

pythonpath = path/to/your/module

Step 4: Reloading Configuration

In Excel, navigate to the Add-ins menu and select PyXLL -> Reload to refresh the configuration and make your function available.

Step 5: Using Your Python Function in Excel

Now, you can use your Python function in Excel just like any standard function:

=hello("me")

Debugging with IDEs (Optional)

If you prefer using IDEs like PyCharm or Visual Studio, you can debug your Python code interactively by attaching your IDE to a running instance of PyXLL.

For troubleshooting, consult the log file for any errors that arise, adjust your code as necessary, and reload PyXLL.
