In this post, I would like to share how to type beautiful latex equations in Microsoft Word and PowerPoint.

In this post, I assume that one of the LaTeX distributions has been installed on your system. On Windows, either TeX Live or MiKTeX is fine.

Type LaTeX equation in Word

Free software

There is a free plugin called texsword which can generate good quality LaTeX equations in Word.

How to install

Download the package from sourceforge, extract it. You will see something like this,

For Office 2007 and later versions, copy the file texsword.dotm to the directory C:\Users\<YOUR_USER_NAME>\AppData\Roaming\Microsoft\Word\STARTUP, <YOUR_USER_NAME> represents your user name. In case that you can not locate this directory in that way, here is how you can find it in your computer:

  • Click on the File ribbon (Office 2010) or Office button (Office 2007)
  • Click Options
  • Click Advanced
  • Scroll down and find a button File Locations. Click on it.
  • Find Startup folder in the list of the Word system folders.
  • Remember where it is and close the Word. Copy the file.

If everything went well, upon next Word launch you will see the TeXsword buttons in the Add-Ins ribbon.

How to use

To insert equations, click the button with TeX label (see image above). There is also a shorcut to insert LaTeX equations: just press ALT+T.

For more usages, please consult the texword_readme.docx file bundled with the texsword.dotm. It has detailed instructions on how to use it.

Commercial and shareware

There is a well-known software MathType which support LaTeX syntax. The only problem is that the license fee is too much for a student. I have found another software which is cheaper and can do the same thing. It is called AxMath and is developed by a Chinese company.

You can use the software free with limited feature1 or you can purchase a license for about $6.12 (¥39) to activate full feature.

After you have installed this software, a ribbon will appear in the word menu.

You can insert inline, display and numbered equations. To change to the LaTeX input mode, click the button in the lower right of panel or press shortcut key Ctrl+Tab.

It support LaTeX command auto-completion once you start typing \, which is convenient.

After finishing equations, you can use Shift+Enter to render the equations.

Type LaTeX in PowerPoint

Download and install

To type LaTeX in PowerPoint, you can use IguanaTex. Download it from here. Following instructions on the website (there is a installation part) and set up IguanaTex properly. Then a ribbon with name IguanaTeX will appear in PowerPoint,

How to use

Type the LaTeX code just as you do in LaTeX,

Click the Generate button to generate LaTeX equations. If you want to update the equation, select the generated image, then click the Edit LaTeX display button under the IguanaTeX ribbon. After finishing editting, click the button Regenerate to regenerate the equation.


  1. But I think the free version is good enough for normal use.
