I\'m trying to highlight certain words in my Google Document. I know I can replace text using document.replace, but it only replaces string itself, not formatting. Is there
I think it's possible with the method setBackgroundColor of class Text in DocumentApp : https://developers.google.com/apps-script/class_text#setBackgroundColor
You'll have to retrieve your words as Text elements. In order to do that you can use the find method of your object Document, then to iterate over the search results and use getElement. Finally, to convert your Element object into a Text object, you can use asText().
Hope it'll work ! ;)
