ForEachCell walks only cells that exist in the loaded worksheet model. It does not scan every possible row and column in the sheet Cells are visited in row-major order. SheetIndex, Row, and Col are 1-based public coordinates. Value is the current cell value. Formula contains the formula text for formula cells and is empty for ordinary value cells Set Cancel to True in the callback to stop the scan early. The return value is the number of callbacks that were made

Primer

procedure TForm1.ReadCell(Sender: TObject; SheetIndex, Row, Col: Integer; const Value: Variant; const Formula: WideString; var Cancel: Boolean); begin Memo1.Lines.Add(Format('%d:%d = %s', [Row, Col, VarToStr(Value)])); if Row >= 1000 then Cancel := True; end; Visited := Workbook.Sheets[1].ForEachCell(ReadCell);
