Workaround for Retrieving Direct Links of All Sheets from URL of 2PACX-### of Web Published Google Spreadsheet

Workaround for Retrieving Direct Links of All Sheets from URL of 2PACX-### of Web Published Google Spreadsheet

This is a sample script for retrieving the direct links of all sheets from the URL like https://docs.google.com/spreadsheets/d/e/2PACX-###/pubhtml of the web published Google Spreadsheet. This sample script can be used for the following situation.

  1. The Spreadsheet is published to Web and the URL like https://docs.google.com/spreadsheets/d/e/2PACX-###/pubhtml is known
  2. You are not the owner of Google Spreadsheet.
  3. You don't know the Spreadsheet ID and Sheet IDs.

Under above situation, unfortunately, the direct links of each sheet cannot be directly retrieved. I think that this is the specification of Google side. So in this post, I would like to introduce a workaround for retrieving the direct links of each sheet under above situation.

Slack Formatting Bar Feedback
There are a couple of problems with the new formatting bar:
1) The icon to turn it on/off doesn't make sense. It's a toolbar, and the "Aa" doesn't get that concept across. It's in a strange place, next to "@" and ":-)", icons that cause an element to come up over the text field without changing it. A lot of smart folks aren't figuring this out (and let's face it, no one reads the fricken' manual.) Don't believe me, check out the replies to this tweet:
https://twitter.com/chockenberry/status/1196992017143779328
2) Once you have the epiphany to turn it off, it doesn't turn off the functionality. I've been using Markdown since it was just a glint in John Gruber's eye, and it's actually easier for me to _read_ text *like this* even when it contains `code`.
If I opt out of the formatting bar, it feels like I should be opting out the fancy completion stuff, too.
