CellVision

Video, playing inside Excel, one cell per pixel. It should not work. It does.

Anyone who enjoys knowing exactly how far a spreadsheet can be pushed.

What it is

CellVision resizes worksheet cells into a square grid, streams frames from a video file with OpenCV, and paints each frame by setting cell fill colours — or ASCII characters — over COM.

It is a novelty, and it is honest about that. Excel was not consulted.

How it works

This is how CellVision works, not a set of steps you can follow yet — it is in development and not distributed.

Install it
CellVision runs on your machine. There is no account to make and no service to depend on.
Point it at your work
It reads what you already have, in the formats you already keep it in.
Keep the result
Output stays where you put it. Nothing is uploaded to make the feature work.
