@KoniWorx The Sprite Sheet Exporter command seems to work with Flash CS6 but doesn't include the extra document with code stuffs for programmers. Tried it in Flash 8 and it didn't work at all apart from displaying "This document must be saved before selection can be exported!!" in the output panel but that's probably because Flash 8 is from 2005.
Still really convenient.

This script is exclusively for the latest version of Adobe Animate or can it be used on older versions of Flash?

I have not tried it on old versions of flash. Give it a go.
