* Paste: whole-column paste and validation without per-cell blowup edit.paste of a whole-column or whole-row copy walked every cell of the copied block (up to the whole sheet) and, for each one, re-cut every validation rule and pushed a one-cell rule. Over a 2M-cell block that is quadratic and the fuzz soak aborted on 34-68 GB allocations. - Paste visits only cells that hold something in the source or the destination; blank onto blank changes nothing (and with an operation stays blank, as in Excel, instead of becoming 0). - Validation pastes as ranges: the pasted rectangle is cut once out of the destination's rules and each source rule comes along as one rule over its translated parts (Skip Blanks or not, as Excel does). - Whole columns and rows paste whole, so destination content further down the columns is replaced, as in Excel. - A paste that does not fit on the sheet is refused, as Excel does, instead of pasting part of the block (whole columns below row 1, whole rows right of column A, a whole column transposed, a block at XFD). - Paste Link, the one paste that writes every cell, is capped at 1,048,576 cells; tiled validation at 100,000 ranges.
