"We don't have a plan to implement insertWorksheetsFromBase64 for Excel on the web at this time. There's a dependency on a feature we require that is not yet in Excel on the web. There's an existing idea request to implement insertWorksheetsFromBase64 here. We ask that any developers affected by this please upvote here. If you can provide comments, especially if you are blocked, this would be helpful to bump up the priority on this."
