DOCX Typeface Changer
Change Every Font, in Every Document, in Seconds
Ever faced the soul-crushing task of updating the font in a massive project? Whether you’re a writer preparing a manuscript for submission or an office professional ensuring brand consistency across dozens of reports, changing fonts manually is a tedious, time-consuming chore.
For writers and novelists, formatting is everything. Agents and publishers often have strict submission guidelines, and being able to switch your entire 300-page manuscript from Times New Roman to Courier in one go is a game-changer. It also allows you to experiment with different typefaces for readability during the editing process without the headache.
In the corporate world, brand identity is paramount. When your company updates its style guide, every document—from proposals to internal memos—needs to reflect that change. Manually opening and editing each file is not just inefficient; it’s a recipe for inconsistency.
What if you could automate the entire process? With the DOCX Typeface Changer script, you can.
How It Works: Your Files Are Always Safe
The biggest fear when running an automated tool is losing your original work. I’ve designed this script with one core principle: safety first.
The DOCX Typeface Changer never alters your original files. It operates in a few simple, guided steps as show below:
[ Click on images to enlarge ]→ The Prerequisite Step
When the script is clicked, it will launch the Python interpreter program, a window that looks similar to your computer’s Command Prompt or Terminal. Do not be afraid. The program is Python, a programming language that is widely used in web applications, software development, data science, and machine learning (ML).
The DOCX Typeface Changer script first needs to check for the python-docx library. This part of the process is important, as the python-docx library is needed by the script to do its job in interacting with .docx Word document files. Without it, the script won’t be able to do anything with a .docx Word document file.
You can read more about Python via the organization’s website:
→ Step 1: You Select a Source Folder
You start by telling the script which folder contains all the .docx Word documents you want to change.
→ Step 2: You Pick a Destination
Choose where in your computer you want to save a duplicated folder with all copied files to be updated by the script.
This ensures that your original source files are not altered; only the copied files inside the duplicate folder will be modified.
→ Step 3: The Script Creates a Safe (Duplicate) Copy
It automatically duplicates your entire source folder, naming it (Modified Copy). All changes happen in this duplicate folder.
→ Step 4: You Choose the New Font
Simply type in the name of the font you want to use (e.g., “Arial”).
→ Step 5: The Magic Happens
The script opens every .docx file inside the copied folder, changes the font of all the text, and saves it.
In the image examples below, I chose the font Georgia for all my .docx Word documents. My work folder is named Book Novel.
Note: The script added (Modified Copy) to the name of the duplicate folder where it will make all the changes. My original work folder is not touched by the script.
→ Step 6: Job done!
All Word documents in the duplicated folder have been modified, and the script opens the duplicate folder upon clicking “OK.”
Your originals remain exactly as you left them.
Prerequisites: What You’ll Need
This script is a simple Python file, but it needs two things on your computer to work its magic.
- Python: This is the programming language the script is written in. The Python program is free, safe, and easy to install on any operating system (Windows, macOS, Linux). Please refer to the guides below for more information.
- The
python-docxLibrary: This is a special toolkit that gives Python the ability to read and write Microsoft Word (.docx) files.
Don’t worry if this sounds technical! Getting set up is straightforward. For detailed, step-by-step instructions, please refer to the following downloadable PDF guides:
- User Guide – DOCX Typeface Changer (PDF File – 755 KB size)
Read this document first before downloading the Python script. It explains DOCX Typeface Changer and how the script operates. - How to Install Python on Windows & macOS (PDF File – 82 KB Size)
A guide on installing the Python interpreter program on your computer. - How to Install the python-docx Library (PDF File – 62 KB Size)
Instructions on installing the python-docx library via Command Prompt or Terminal.
Once you have those two prerequisites on your computer, you’ll be ready to run the DOCX Typeface Changer script and take back control of your documents. And as long as you have the two prerequisites on your computer, or all your home and work computers, you can keep using the script to change the typeface (font) of your .docx Word document files.

This Python script was developed out of necessity. I was working on a science fiction graphic novel project that had over 90.docx Word document research and development files that needed to all have their typefaces (font) changed for e-book and PDF viewing. (And, no, I was NOT going to use Arial or Calibri.) I was not about to sit there for hours pushing buttons like a monkey, opening each Word document file in LibreOffice (alternative to Microsoft Word) and repetitively clicking the font list to change the contents to the Lusitana typeface (font). All the while, hoping that someone would put my misery to an end.
That’s… not how a nerd life should be. I should be on Steam, playing Stellaris or raging over how long the queue is on Battlefield 6! I have a real purpose in life. I matter to the world!
Then I remembered the words of a wise friend, “Work smarter, not harder.”
Mr. Freddy Nakamura was the underdog sage of our century. A real street-smart guy who learned how to take control of his life—one failure at a time. Nakamura-sensei was like my guru… until he fell off his balcony trying to shoo away a bunch of crows with a broomstick. Technically, he lived through the fall. But a portion of the rickety and rusted balcony fell on him… along with the crows perched on the balcony rails.
But my point is, the man was correct about seizing your life instead of being a slave by it.
I would rather spend an entire day trying to figure out another way to do something—a task, an action, a repetitive procedure—so that I would never have to do it again. Thus, the Python script DOCX Typeface Changer was born out of the need to be lazy. (But smart lazy.) With it, I’ll never have to sit there, repetitively and manually, changing the typeface (font)… of every… single… Word document.
Go ahead and try the script, and take back your life!
