Manually
To retrieve a Spreadsheet in HTML format you can export it accordingly by clicking on File -> Download -> Web Page. That will get you a zip
file with the HTML of your Spreadsheet that you can rename as you like without revealing the Spreadsheet ID.
With Apps Script
You can also automate this process creating an Apps Script function that for instance gets triggered every time you click on an inserted button (to do this you can simply click on the menu bar Insert -> Drawing and the on the three dots of the top right of this button click on assign script and set it to the name of your function).
The following function will display a modal dialog on the Spreadsheet when run that if the user clicks on Download
it will automatically download the zip
file with the Spreadsheet in HMTL
format. This function has self explanatory comments :
function downloadHTML() {
// Get ID of the Spreadsheet
var id = SpreadsheetApp.getActive().getId();
// Get the download URL of this Spreadshet in format HTML on the background
var url = "https://docs.google.com/a/mydomain.org/spreadsheets/d/" + id + "/export?exportFormat=zip&access_token=" + ScriptApp.getOAuthToken();
// Download when clicked on the button of the opened dialog
var html = '<input type="button" value="Download" onClick="location.href=\'' + url + '\'" >';
// create an HTML output from the given string
var dialog = HtmlService.createHtmlOutput(html);
// Show a modal dialog on the Spreadsheet UI when the function is run with the Title download
SpreadsheetApp.getUi().showModalDialog(dialog, "Download");
}
