Subscripts are text or characters written below a main line of text. Let’s learn how to use subscript in Excel.

CO₂. H₂O. You might recognize these formulas for carbon dioxide and water. In both cases, the “2” is a subscript. Often used in math and science, it’s helpful to learn how to quickly type these in Excel.

We’ll learn how to type H₂O in Excel. Begin by clicking into any open cell in your workbook. Then, type H2O. As you’ll notice, Excel won’t automatically apply the subscript.

Potential Uses for Subscripts in Microsoft Excel

You may be wondering about the potential uses for subscripts in Excel. In fact, these commonly occur in STEM (science, technology, and math) fields and applications. Here are a few common examples:

• Chemical formulas like those above (CO_{2, H2O)}
• Math equations with sequence terms (F₅), where 5 is the fifth term.
• Computer coding applications (C₁₀)

As you can see, it’s easy to add subscripts in Microsoft Excel. This helps you perform your work faster.
