#23Initially, I wa puzzled by how the grid could be showing placeholders (the grey "A1", "A2", etc.) when there's no placeholder attribute defined in the source code. Then I discovered that the code running in the demo is not actually the showcased 220-byte source code at all. The code is still impressively small, but you should fix this — it's misleading as is.

Thanks for mentioning/enjoying it :)

#27Doesn't work with decimals.
It does work, but you need to use dots, not commas.
Ex:
A1 => "4.5"
A2 => "=A1+2"

#28Super impressive and I love code-golfing but the title is slighlty misleading since the HTML part of the app, the cells, seem not to be included in the 220b. Still great.

I think that's probably just because it's been revised and the placeholders were added after.
To be fair, it only adds an extra 18 chars, taking it up to 238-byte in size.
EDIT Here it is once you add the extra property:
(o=b=>{for(j in a)for(i in a)y=a[i]+-~j,b?document.write([[""][i]]+""):eval(y+(".value"+o[y]).replace(/[A-Z]\d/g," +$&.value"))})(a="ABCD")
