I am curious to know what is App Sheet and what is the use of it.

It's a customizable frontend for a database.

Also,

1. A low-code platform able to handle logic and structured control flows.
2. Being part of Google Workspace Apps enable seamless integration with Google Drive, and now Data Studio and Apps Script.
3. Call webhooks, send emails and  SMS msgs, generate files directly from the app. 
4. Integration with Apps Script enables communication with other Google Workspace apps and any external system/platform through API.
