Insert the Xi upper case Ξ, and Xi lower case ξ symbols in Microsoft Word, Excel, PowerPoint, or Outlook.  Both in Office for Windows and Office for Mac. 

Xi (uppercase Ξ / lowercase ξ) is the 14th letter of the Greek alphabet. The symbols are used within various contexts. The uppercase letter is often used in pure mathematics and physics, whereas the lowercase letter is used in similar areas, but it can often be used in astronomy representing the initial ass function and the correlation function.

How Xi upper case and Xi lower case look in different fonts. 

Here’s some examples of how the Xi upper case and Xi lower case symbols look in common Office fonts in Word 365.

Xi uppercase and lowercase symbol codes 

These are the important code numbers or values you’ll need to enter the two symbols.

Use the Alt + X shortcut in Word for Windows, for example type 039E then Alt + X to enter Ξ.  

Or enter the value into Character Code fields in Symbol dialog boxes to jump to that symbol. 

Xi uppercase symbol Ξ     U+039E
Xi lowercase symbol ξ     U+03BE

Quick access for commonly used symbols. 

If you use a symbol often, a fast way to enter it is AutoCorrect. 

Once in a document you can copy it to AutoCorrect and make your own shortcut. 

Word, Excel, PowerPoint and Outlook 

Insert | Symbols | Symbol and look for the Xi symbols using Character Code 039E or 03BE.

Window 10 Emoji Panel

The Windows 10 Emoji Panel has the Xi symbol Ξ. Use Win + . (period/fullstop) to open the panel.

Choose the Symbols tab (the third of the top row icons), then the Language Symbols section which is marked by the capital Ω … handy that.  To find the Xi letters, scroll down the list.

Windows Character Map  

Similarly, the Windows Character Map accessory in all Windows releases. Character Map has a search feature, something missing from the Insert | Symbol in Office.  

Or use one of the hex character codes to jump to the right part of the list.    

MacOS and Office for Mac inserting characters 

On a Mac, to enter the Male, Female or combo symbol: 

  • Command + Control + Spacebar shortcut to open the Character Viewer.    
  • Search for “Xi“ should find the symbol you need as the first result. 

Despite the name Character Viewer, the Apple system tool will also insert characters into any program, including Office for Mac.
