Simplify Your Google Docs: Removing Specific Text from H3 Headings with Google Apps Script


Do you often find yourself needing to clean up specific headings in your Google Docs? Maybe your document has numerous H3 headings that start with “Question” followed by a number, and you want to streamline these headings by removing the redundant word and number. This manual task can be time-consuming and prone to errors. Luckily, Google Apps Script provides a powerful way to automate this process. In this blog post, we’ll introduce a script that identifies H3 headings starting with “Question” and a number, removes the specified text, and leaves you with cleaner, more concise headings.

The Script

Here’s the complete removeQuestionAndNumberFromH3 function:

function removeQuestionAndNumberFromH3() {
// Get the active document
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();

// Get all the paragraphs in the document
var paragraphs = body.getParagraphs();

for (var i = 0; i < paragraphs.length; i++) {
var paragraph = paragraphs[i];

// Check if the paragraph is an H3
if (paragraph.getHeading() === DocumentApp.ParagraphHeading.HEADING3) {
var text = paragraph.getText();

// Check if the paragraph starts with "Question"
var regex = /^Question\s+\d+/;
if (regex.test(text)) {
// Remove "Question" and the following number
var newText = text.replace(regex, '').trim();
