Word-Math

I built Word-Math as a small Windows tray utility that evaluates arithmetic directly inside Microsoft Word. I can type an expression on a line, end it with =, press the configured hotkey, and Word-Math replaces the line with the solved result.

Example:

1250 + 349.99 =

becomes:

1250 + 349.99 = 1,599.99

Features

• Works with the active line in Microsoft Word.
• Supports +, -, *, x, /, decimals, commas, and parentheses.
• Runs from the Windows system tray.
• Lets you change the hotkey from a simple settings window.
• Saves the preferred hotkey in hotkey.txt.

Requirements

• Windows
• Microsoft Word
• Python 3.10+
• Packages listed in requirements.txt

Setup

Install dependencies:

python -m pip install -r requirements.txt

Run the app:

python WordMath.py

By default, Word-Math uses:

ctrl+alt+m

Usage

1. Open Microsoft Word.
2. Type a supported math expression on its own line and end it with =.
3. Press the configured hotkey.
4. Word-Math replaces the line with the expression and result.

Supported examples:

42 + 18 =
1,250 x 4 =
(100 + 25) / 5 =
-12.5 + 40 =

Notes

Word-Math only evaluates basic arithmetic. I intentionally block Python code execution and unsupported expression types.

The app communicates with Word through the Windows COM interface, so it must run on a Windows machine with Microsoft Word installed.

Status

This is an early utility project. Future improvements could include packaging it as a Windows executable, adding tests, supporting selected text, and improving the tray settings interface.
