Data2Slide
Good for turning a plain spreadsheet or report into a deck with charts nobody has to build by hand, and the offline HTML export means the result isn't locked behind a login. The catch is that everything about who runs it, and how it handles messy or multi-sheet data, had to be pieced together from outside write-ups rather than the product itself.
Pros
- parses CSV, Excel, PDF and screenshots into charts without manual setup
- exports a self-contained offline HTML file instead of only a hosted link
- one free 10-slide deck to test before paying
Cons
- a single paid tier, so no cheaper option for occasional use
- no confirmed API for pulling generated decks into another workflow
- the company behind the product could not be identified independently
