How to Insert Upright Custom Operators in Word Online Equations
Product
Word Online
Device & OS
not provided
Scenario
Formatting complex mathematical equations with custom operators while using the web-based version of Microsoft Word.
Observed behavior
Word for the web lacks advanced equation formatting options, preventing users from easily converting default italicized math text into upright, normally spaced text for custom operators.
Before you start

Ensure you have access to the desktop version of Microsoft Word, as the web-based version has limited equation editing capabilities.

Solution 1Recommended

Use Microsoft Word Desktop Application

Switching from Word Online to the desktop version provides access to the full-featured equation editor, allowing you to format text as upright.

Word Online is heavily simplified and lacks advanced equation formatting tools. To fully control text spacing and styles inside an equation, you must use the desktop application for Windows or Mac.

1
Open in Desktop App

While viewing your document in Word Online, click on the 'Editing' or 'Viewing' button on the top ribbon and select 'Open in Desktop App'.

2
Access the Equation Editor

In the desktop application, place your cursor where you want the equation. Go to the 'Insert' tab and click on 'Equation'.

3
Apply Normal Text Formatting

Select the text or custom operator within the equation box that you want to be upright. On the 'Equation' tab that appears in the ribbon, click on the 'Normal Text' button in the Tools group. This will remove the italicized math formatting and make the text upright.

Use Microsoft Word Desktop Application
Avoid Repeated Conversions: Avoid repeatedly converting the same document back and forth between different office applications (like LibreOffice and Word), as specialized equation formatting may be lost in the process.

Insert Upright Custom Operators Using WPS Office

WPS Office provides a comprehensive, built-in Equation Editor in its free desktop application. You can easily insert equations and format custom mathematical operators as normal, upright text without needing expensive third-party add-ins.

  1. 1. Download and Install WPS Office: Download WPS Office for free and open your document in the WPS Writer desktop application.
  2. 2. Open the Equation Editor: Navigate to the 'Insert' tab on the top ribbon and click on the 'Equation' icon.
  3. 3. Type Your Custom Operator: In the Equation Editor window, type the custom operator or text you need inside the formula.
  4. 4. Apply Upright Text Style: Highlight the typed text, click on the 'Style' menu at the top of the editor, and select 'Text' to make the characters upright and normally spaced.
  5. 5. Insert into Document: Close the Equation Editor window. Your newly formatted, upright custom operator will be inserted directly into your document.

Frequently Asked Questions

Why does my equation formatting change when switching between LibreOffice and Word Online?

Converting documents back and forth between different office programs can cause formatting loss due to differences in file structures. Word Online has significantly fewer equation features and may not preserve the specialized formatting originally created in LibreOffice.

Can I use the MathType add-in directly in Word Online?

While Microsoft Word supports add-ins, complex tools like MathType are optimized for the desktop application. Word Online's technical limitations may prevent advanced equations from rendering or editing properly in the browser.

How do I remove italics from text inside a Word equation?

In the Microsoft Word desktop app, highlight the specific text within your equation block, navigate to the 'Equation' ribbon tab, and click the 'Normal Text' button. This removes the default mathematical italicization, turning it into standard upright text.
