Automate Text Styling in Google Docs: Bold Questions with Google Apps Script

function boldQuestions() {
  const doc = DocumentApp.getActiveDocument(); // Access the current Google Doc
  const body = doc.getBody(); // Get the document's body content
  const paragraphs = body.getParagraphs(); // Get all paragraphs in the document

  const questionPattern = /^Question \d+/; // Regular expression to match "Question 1", "Question 2", etc.

  paragraphs.forEach(paragraph => {
    const text = paragraph.getText(); // Get the text of the paragraph
    if (questionPattern.test(text)) { // Check if the text matches the pattern
      const startIndex = text.indexOf("Question"); // Find the starting position of "Question"
      const endIndex = text.indexOf(' ', startIndex + 9) === -1 ? text.length : text.indexOf(' ', startIndex + 9); // Adjust for no space
      paragraph.editAsText().setBold(startIndex, endIndex - 1, true); // Apply bold styling
    }
  });

  Logger.log("All 'Question' elements have been bolded.");
