Google Docs - Format Matching Text Script

About

NOTE: This page is a daughter page of: Google Docs App Scripts

This demos a Google Docs Add On / App Script to format text. :)

What the thing looks like after a run

Instructions

The right API to help is the Google Docs API... but that's slow to process, so here's what you need to do to create a new menu item that does something:

1. Create a brand new Google Doc ............... (tip: Try typing into Chrome: docs.new)
2. Click menu bar: Extensions > App Scripts.
3. Enter the javascript code below into the Script Editor and hit "Save" and "Deploy" (as "Editor Add-On")
   ..... (tip: You can hit the play button to test one of the functions before saving)
4. Reload your Google Doc and approve permissions.
5. Run the Script by clicking the new menu item that appears: Special Formatting > Format Stat Numbers.

(see pictures of this process)
