• 🔍 Object Management - Save and re-use objects in python kernel
• 🐛 Debugger - Set breakpoints, step through code, and inspect variables
• 🎨 Theming - Customizable dark/light themes for the IDE

Requirements

• Operating System: Windows 10/11 (64-bit) / Other platforms are enabled but not tested
• Python: 3.10 or higher
• Microsoft Excel: 2016 or later (with Office.js Add-in support)

Installation

pip install xpycode_master

Quick Start

1. Install XPyCode:

   pip install xpycode_master
   

2. Start the XPyCode Master server:

   python -m xpycode_master
   

3. The Excel Add-in will be automatically registered.

   Open Excel and look for the XPyCode in Add-Ins -> More Add-Ins -> Shared Folder

4. Launch in Excel:

   [Open Console] --> [<> Editor ]
   

5. In XPyCode Editor

   • Add a python module: Right click on the workbook -> New Module
   • Start coding, using xpycode module:

   def updateExcelFromPython():
      import xpycode
      ws=xpycode.worksheets.getActiveWorksheet()
      rA1=ws.getRange("A1")
      rA1.values="Hello"
      rA1.format.fill.color="yellow"
   

Running as a Service

XPyCode can run as a system service for automatic startup:

# Install and start as a service
python -m xpycode_master service install

# Check status
python -m xpycode_master service status

# Stop service
python -m xpycode_master service stop

Supported on Windows, Linux (systemd), and macOS (launchd). See Service Management for details.

Addin Hosting Modes

XPyCode supports two modes for running the Excel add-in:

External Mode (Default)

The add-in UI is served from https://addin.xpycode.com. This is the default mode and requires no certificate management.

python -m xpycode_master

Local Mode

The add-in UI is served from a local HTTPS server on your machine. Requires self-signed certificates.

python -m xpycode_master --use-local-addin

!!! warning "Mode Switch Cache Clearing" When switching between local and external modes, XPyCode will automatically clear the Office add-in cache. This affects all Office add-ins, not just XPyCode. You may need to restart Excel after switching modes.

Usage

Running Python Code

1. Open a workbook in Excel
2. Click "Open Console" in the XPyCode ribbon
3. Open Editor with "<>" button
4. Right click on the workbook name and add a python module
5. Write Python code in the editor
6. Press F5 or click "Run" to execute

Publishing Custom Functions

# In your module, define a function
def add_numbers(a: float, b: float) -> float:
    """Add two numbers together."""
    return a + b

Then use the Function Publisher in the IDE to expose it as an Excel formula: =ADD_NUMBERS(A1, B1)

Package Management

1. Open the Package Manager panel in the IDE
2. Search for a package (e.g., "pandas")
3. Select version and optional extras
4. Click "Install/Update" to install for the current workbook

Configuration

Configure themes, pypi urls, console preferences, ... in File/Settings menu

Excel Sample

You will find an Excel workbook sample in xpycode_master\excel_sample.
