I have written a function, setParagraphToRichText which accepts a GoogleAppsScript.Document.Paragraph and a string. The string is a stringified JSON blob that defines the text and attributes of a given paragraph.

/** * * * @param {GoogleAppsScript.Document.Paragraph} paragraph * @param {string} jsonString */ function setParagraphToRichText(paragraph, jsonString) { const text = paragraph.editAsText();
