Coverting Indesign to Google Slides

Picasso could work in crayons. 

Whatever merits the actual presentation platform may have, PP's content and design tools are one step above toy printing blocks and ColorForms.

That's really it. I was on a mobile device earlier and couldn't give an extended answer, but TSN has summed it up.

In my opinion, Powerpoint and its clones are absolutely the worst tools in the creative spectrum, at least, that are in wide user or definitive for their niche. Even Word has an advanced/pro layer of features and controls; PP is stuck at a finger-painting level for relatively unskilled administrative assistants. Every release adds more bells and whistles and shiny gimcrackery without adding a single really useful feature.. like, you know, styles.

And next to nothing imports to PP etc. with any degree of "live edit" or fancy-feature support. So you can use the primitive tools to build template-based, wibble-wobble, flash-bang-zoom presentations that will entrance everyone under 6 and bore everyone else (except the big bosses, who equate zoomy text and page curls and animation with "really getting the message across, go team!")... or you can use a real tool and export to JPEG as a 'background' that's actually the whole slide, using nothing of the actual PP app except (hopefully) subtle and graceful page transitions.

Or you can export to PDF and use its less sophisticated but not bare-bones presentation features. But Powerpoint it is for corporate America, so choose your path wisely. (My choice is usually to bow out and let the next unlucky consultant do it.)
