I am a Google Developer Expert and decided to investigate Google Apps Script in my spare time. The more I investigated the more content I created so this site is extremely rich. Now, in 2019, a lot of things have disappeared or don’t work anymore due to Google having retired some stuff. I am however leaving things as is and where I came across some deprecated stuff, I have indicated it. I decided to write a book about it and to also create videos to teach developers who want to learn Google Apps Script. If you find the material contained in this site useful, you can support me by buying my books and or videos.
