One other point of feedback, I clicked the "How it works" link, and when the page scrolled down, the animation was already on step 4, but that text is small, so I didn't realize I was watching the last step. I was a bit confused.
Maybe consider using a scroll position detection library to hold the animation until the user has it in view, or use something more clear to indicate which step is being illustrated:
"Create visualizations from your spreadsheet data"
That's what this does. The "missing link" cliché didn't score any points with me, but the product looks extremely cool.
