Method #3: Use the Subscript Option

The Subscript option is an icon that can be added to any ribbon for quick access. We will first explain how to change your ribbon to always show the Subscript icon. This will make it easier to access in the future. Do this if you often have to change a text or number to a subscript.

Step #1: Open your Excel workbook

Step #2: Select Customize the Ribbon

Right-click anywhere on the ribbon and select the Customize the Ribbon option from the three options that appear.

An Excel Options dialog box will open. 

In the Main Tabs section, select a tab where you want the Subscript icon to appear. 

For our example, the Insert tab is selected.

Click on New group or an existing group. 

This is where you will find the Subscript option. 

For our example, we have chosen the New group option.

Step #5: Select the Subscript command

Step #6: Click the Add option

Once you select your command to be added, you can click the Add option.

Close the window.

Now, go to your Excel spreadsheet and select the part of the cell to be converted into a subscript.

Go to the tab where you decided to add Subscript to the menu options.

In our example, it is the Insert ribbon.

Click on the Subscript icon.

You can see that the 2 has been changed to a subscript. 

Once you’ve customized the ribbon, you can directly use the Subscript option.

You can also use the Equation option to add a subscript. You first insert an equation box, select the type of equation and add data to it.

Step #1: Open your Excel workbook

Open an existing workbook if you have one. Otherwise, create a new workbook by clicking on Blank workbook.

Step #2: Insert an Equation box

Click on the Insert tab in the main menu bar.

In the Insert ribbon, at the extreme right, you will find the Equation icon. 

Double-click the Equation icon.

This will insert an equation box in your document, and the ribbon will change.

Step #3: Select Script and click on Subscript

In this new Equation ribbon, click on the Script icon.

A drop-down menu will appear.

Select the second option, i.e., the Subscript option.

Step #3: Enter your data

You can see two boxes. Enter the data in the respective boxes.

Tip: Increase your font size to add data to the boxes, and then reduce the font size again once done.

You can now see your text or number with the subscript.


Method #5: Use the Ink Equation option

You can also draw your Equation and Excel will convert it to text and insert it into your sheet.

The Math Input Control dialog box will open. 

Here, you can draw what you want and Excel will convert it for you. 

You can see that Excel has identified 2 as a subscript and kept it as such.

Step #4: Review and click on Insert

You can review if it is correct in the text box above the drawing space. 

Confirm if it is right and click on the Insert button.

You can now see that the text with the subscript has been inserted into your Excel sheet.

Third-party websites can be used to convert numbers or text to subscripts. Our pick for this method is Lingo Jam’s subscript generator.

Step #3: Enter the text 

You can now enter your number or text in the first box. 

You will see the subscript generated in the second text box.

Step #4: Copy the subscript

Step #4: Select Custom

In the new window that opens, under the Number tab, select the Custom option at the bottom.

Step #5: Enter the custom field

In the Type field, enter 0 and the subscript you desire. 

For this, you can copy-paste it from a third-party website as done in the previous method. 

You will see the subscript in the list of options now. 

Click on that option, and click on the OK button. 

You can now see that the subscript has been added to all the numbers.
