Greek Letters: How to Insert Alpha, Delta, Omicron in Excel

In Mathematics, many Greek letters have meanings. For example, the delta symbol, or the sigma character. Also, with nowadays naming the COVID-19 variants after Greek letters, you might need to use them in Excel. Here are 5 simple methods of how to add them to Excel cells and to use them in Excel charts – in Windows and Mac!

Method 1: Use the Symbol window to insert Greek letters

The “traditional” way to insert the sign showing the difference in Windows is through the Insert Symbol window:

Insert the Delta Sign in Windows.
Insert the Delta Sign in Windows via the Insert Symbol window.
  1. On the Insert ribbon, click “Symbol” (the right-most button).
  2. In the Symbol window, select “Unicode (hex)” in the from field.
  3. Type the number of your desired Greek letter into the “Character code” field (here 0394 for delta Δ). You should now see the Greek character selected above.
  4. Click on Insert to insert the symbol into the cell or chart.

This table has all the values you type into the “Character code” field.

Method 4: Copy & paste

Probably not as beautiful, but it usually works: Alternatively, just copy and paste the Greek letters from one of the tables above.

This method also works under MacOS

Method 5: Insert Greek letters in MacOS

As said already, the method 3 and four above also work under MacOS.

This method

It’s almost the same in Mac OS as in Windows, but the window looks a bit different. Still, you have to go to the Insert ribbon and click on Symbol on the right-hand side:

Insert the delta symbol on a Mac with the Character Viewer (very similar to Windows).

  1. On the Insert ribbon, click on Symbol (on the right-hand side).
  2. In the Character Viewer, go to Mathematical Symbols.
  3. Insert the ∆ by double-clicking on it.

Add the Greek characters to a chart

You want to show Greek characters on a chart? It works the same way as described above. The only difference: Insert a text field first.

Before you can insert a Greek letter on a chart, insert a Text Box on it.
Before you can insert a Greek letter on a chart, insert a Text Box on it.

In order to do this, select your chart. Then go to the Insert ribbon. On the right-hand side, click on the button “Text Box” and draw it onto the chart. Now, you can simply copy & paste or insert the Greek letter there.
