Enumerates the loaded cells in a classic XLS worksheet and calls an application callback for each cell
Syntax
type
TXLSCellReadEvent = procedure(
Sender: TObject;
SheetIndex, Row, Col: Integer;
const Value: Variant;
const Formula: WideString;
var Cancel: Boolean) of object;
function ForEachCell(Callback: TXLSCellReadEvent): Integer;
Remarks
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 is the cell formula text, or an empty string for non-formula cells
Set Cancel to True in the callback to stop the scan early. The return value is the number of callbacks that were made
Example
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);
