Code:

uses

ComObj;

 

function Xls_To_StringGrid(AGrid: TStringGrid; AXLSFile: string): Boolean;

const

xlCellTypeLastCell = $0000000B;

var

XLApp, Sheet: OLEVariant;

RangeMatrix: Variant;

x, y, k, r: Integer;

begin

Result := False;

// Create Excel-OLE Object

XLApp := CreateOleObject('Excel.Application');

try

   // Hide Excel

   XLApp.Visible := False;

 

   // Open the Workbook

   XLApp.Workbooks.Open(AXLSFile);

 

   // Sheet := XLApp.Workbooks[1].WorkSheets[1];

   Sheet := XLApp.Workbooks[ExtractFileName(AXLSFile)].WorkSheets[1];

 

   // In order to know the dimension of the WorkSheet, i.e the number of rows

   // and the number of columns, we activate the last non-empty cell of it

 

   Sheet.Cells.SpecialCells(xlCellTypeLastCell, EmptyParam).Activate;

   // Get the value of the last row

   x := XLApp.ActiveCell.Row;

   // Get the value of the last column

   y := XLApp.ActiveCell.Column;

 

   // Set Stringgrid's row &col dimensions.

 

   AGrid.RowCount := x;

   AGrid.ColCount := y;

 

   // Assign the Variant associated with the WorkSheet to the Delphi Variant

 

   RangeMatrix := XLApp.Range['A1', XLApp.Cells.Item[X, Y]].Value;

   //  Define the loop for filling in the TStringGrid

   k := 1;

   repeat

     for r := 1 to y do

       AGrid.Cells[(r - 1), (k - 1)] := RangeMatrix[K, R];

     Inc(k, 1);

     AGrid.RowCount := k + 1;

   until k > x;

   // Unassign the Delphi Variant Matrix

   RangeMatrix := Unassigned;

 

finally

   // Quit Excel

   if not VarIsEmpty(XLApp) then

   begin

     // XLApp.DisplayAlerts := False;

     XLApp.Quit;

     XLAPP := Unassigned;

     Sheet := Unassigned;

     Result := True;

   end;

end;

end;

 

 

procedure TForm1.Button1Click(Sender: TObject);

begin

if Xls_To_StringGrid(StringGrid1, 'C:\Table1.xls') then

   ShowMessage('Table has been exported!');

end;
