Requirements

• Operating System: Windows 10/11 (64-bit) / Other platforms are enabled but not tested
• Python: 3.9 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 XPyCode Master:

   • For a one-shot test run:

     python -m xpycode_master
     

   • For recurring usage:

     python -m xpycode_master --setup
     

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"
   

Upgrading

Check for and install updates:

# Check if an update is available
python -m xpycode_master --upgrade --check

# Upgrade interactively
python -m xpycode_master --upgrade

# Upgrade without confirmation
python -m xpycode_master --upgrade --yes

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.
