Hola elmago00.

De nada.

Agregando un TButton, un TSaveDialog y muy poco código, podes continuar el anterior:

Código Delphi [-]
...
procedure SaveDump(aFileName:TFileName; SG: TStringGrid);
var
  c,r: Integer;
  s: string;
begin
  with TStringList.Create do
  try
    for r:= SG.FixedRows to SG.RowCount-1 do
    begin
      s:= '';
      for c:= 0 to SG.ColCount-1 do s:= s + SG.Cells[c,r] + ' ';
      SetLength(s,Length(s)-1);
      Add(s);
    end;
    SaveToFile(aFileName);
  finally
    Free;
  end;
end;
...

procedure TForm1.btnSaveToTxtClick(Sender: TObject);
begin
  with SaveDialog1 do
  begin
    Filter:= '*.txt';
    DefaultExt:= '*.txt';
    if Execute then
      SaveDump(FileName, StringGrid1);
  end;
end;
