TXLSXCells class

Cell collection exposed by TXLSXWorksheet.Cells; provides typed access by row/column, A1 reference, or used-range enumeration The class is part of the XLSX facade (lxHandleX) and is reached through the owning workbook or worksheet; instances are not normally created directly by application code.

StructureGeneration — changes when cell topology or traversal storage changes, but remains stable for content-only edits to existing cells

function RowUpperBound: Integer — the 1-based row at or below which every cell of the collection lies (an upper bound, not the exact last row); cheap enough for per-cell use, and the workbook reader uses it to flag reads below row 65536 as out-of-used-range

function CompactStyledBlankPayloads — deduplicates style-only blank cells by sharing one canonical style payload per distinct format, returning the number of cells compacted
