One can copy/paste into and out of Excel. It seems like there is a basic \n and \t tab protocol that is being followed.
- How exactly could I
peek insideto see the mechanics? - Do those mechanics change on OS as copy/paste is an OS event?
- How do they change in a web setting (e.g., copy from Excel 2010 to a cloud version)?
Fundamentally, this question arises because within Excel if you copy/paste it will update the REFERENCES of your formulas. That tells me that under the hood, it captured during copy and paste the attributes of the CELLS?
- How to
peek insidethe attributes of the CELLS being copied and pasted (the FORMULAS)? - Is it encrypted so it can't be viewed?

externalweb app, and someone COPY/PASTED cells from EXCEL into that APP, I could know "WHERE THE CELLS" were located, and PROPERTIES/FUNCTIONS on each.
