Hola

quizas el siguiente ejemplo te pueda ayudar, es utililizando el componente TExcelAplication, del palette Servers.

Receta:

Ingredientes en delphi:
1)TForm of course
2)TQuery
3)SaveDialog
5)TExcelapplication
6)bitButton
7)dbGrid


procedure TForm1.bbtnExportToExcelClick(Sender: TObject);
var
LineNumber, LCID : Integer;
LineString : string;
begin
with SaveDialog1 do
begin
FileName :='';
Filter:= 'Excel files|*.XLS;All Files|*.*';
DefaultExt := 'XLS';
Title := 'Exporting to Excel';
if execute then
begin
query1.Open;
LCID := GetUserDefaultLCID;
with ExcelApplication1 do
begin
connect;
try
visible[LCID] := true;
Workbooks.Add(EmptyParam,LCID);

//Paso 1
Range['A1','J1'].Value := VarArrayOf(['Order No',
'Cust No','Sale Date','Emp No',
'Ship Via', 'Terms','Items Total',
'Tax Rate','Freight','Amount Paid']);

//Paso2 Se definen formato de celdas (alineacion de texto, margenes, fuente, etc.)
with Range['A1','J1']do
begin
HorizontalAlignment := xlcenter;
VerticalAlignment := xlBottom;
Wraptext := false;
Orientation := 0;
ShrinkTofit := false;
MergeCells := false;
Font.Bold := true;
end;

Query1.First;
LineNumber := 1;

//Paso 3, comenzamos a enviar datos a Excel
While not query1.Eof do
begin
Inc(lineNumber);
LineString := IntToStr(LineNumber);
Range['A'+LineString, 'J'+LineString].Value :=
VarArrayof([Query1OrderNo.value, Query1CustNo.Value,

//Paso 4
FormatDateTime('d-mmm-yy',Query1SaleDate.Value),
Query1EmpNo.Value, Query1ShipVIA.Value,
Query1Terms.Value, Query1ItemsTotal.Value,
Query1TaxRate.Value, Query1Freight.Value,
Query1AmountPaid.Value]);
Query1.Next;
end;

//Paso 5
Range['H2','G'+LineString].NumberFormat := '0.00%';
Range['G2','G'+LineString].NumberFormat := '$#,##0.00';
Range['I2','I'+LineString].NumberFormat := '$#,##0.00';
Range['J2','J'+LineString].NumberFormat := '$#,##0.00';
Range['A1','J'+LineString].AutoFormat(xlRangeAutoFormatlist1, true,
true,true,true,true,true);
Range['A1','J'+LineString].Columns.AutoFit;

ActiveWorkbook.SaveAs(FileName,xlNormal, '', '', false, false,
xlNochange,xlUserResolution,False,EmptyParam,EmptyParam,
LCID);
Quit;
finally
disconnect;
end; //try
end; //with Excelapplication1
end; //if execute
end; //with Savedialog1

end;


Tip adiconal

Range("A1").Select
ActiveCell.FormulaR1C1 = "Order No"

Es equivalente en Delphi a:


Range['A1','A1'].select;
ActiveCell.FormulaR1Ci := 'Order No';

Siempre es mejor utilizar arreglos para insertar en Excel datos por renglon, que celda por celda

Range['A1','J1'].Value := VarArrayOf(['Order No',
'Cust No','Sale Date','Emp No',
'Ship Via', 'Terms','Items Total',
'Tax Rate','Freight','Amount Paid']);

Saludos!!

Pd. Espero te sirva de algo
