underline word in google docs

[Wesley Santos]

Hellow guys, Is there any function or mode in apps script where I can remove the default underline from misspelled words and replace it with a custom form? in google docs

Something like the extension for chrome grammarly does

Not easily unfortunately. Apps script has no access to built in spell check.  Your best bet would be finding some third party library that can detect spellings

As mentioned, not easily. Apps script works on the backend google servers, while you want to change what is happening in the browser. That is why Grammarly is a browser extension, because it changes the css at the browser level, then I'm guessing uses javascript to send the corrections back to the google Docs API. That is why you have to authorize it with your account.
