This is a sample script for parsing HTML using Google Apps Script. When HTML data is converted to Google Document, the HTML data can be parsed and be converted to Google Document.

So I could came up with this method.
For those frustrated by the limitations of the Google Sheets
=IMPORTHTML() function this might be a useful Google Apps Script alternative solution. As part of this the script fetches any publicly accessibly webpage and turns any tables into a 2D array.
