[Google Sheets] Word Highlighter (made using Google Apps Script)

I have created a handy highlighting tool using Google Sheets and Google Apps Script. The specification of this tool is very simple.

1. The user pastes a message into the certain cell (A2).
2. The tool checks if the message contains some words which listed in another dedicated sheet(Spam Word List).
3. The tool highlights (bold and color red) the found words in the message.

Here is a nice post demonstrating how you can use Google Apps Script to highlight keywords within a Google Sheets cell. The solution uses  SpreadsheetApp.newTextStyle() to create a custom style which is then applied to part of the cell text.
