xls to stringgrid

[FlavioMacedo]

Is there any way to load an xls or cvs file directly into a stringgrid?

I found this on StackOverflow:

procedure FillStringgrid;
// Split the line of text into individual entries
  procedure Split(const Delimiter: Char; Input: string; const Strings: TStrings);
  begin
    Assert(Assigned(Strings));
    Strings.Clear;
    Strings.Delimiter     := Delimiter;
    Strings.DelimitedText := Input;
  end;


var
  strlst: Tstringlist;
  myfile: TextFile;
  search: string;
  i, j  : Integer;
begin
  i := 0;
  AssignFile(myfile, 'filepath'); // specify your file path here
  Reset(myfile);
  while not Eof(myfile) do
  begin
    Readln(myfile, search);
    strlst := Tstringlist.Create;
    Split(' ', search, strlst); // get the no's separated by the delimiter
    // adjust your column count based on no of entries
    if StringGrid1.ColCount < strlst.Count then
      StringGrid1.ColCount := strlst.Count;
    StringGrid1.rows[i]    := strlst; // adjust the row count
    inc(i);
    StringGrid1.RowCount := i;
  end;
  // free stringlist and textfile
  CloseFile(myfile);
  strlst.Free;


  // fill in the blank entries with 0
  for i := 0 to StringGrid1.RowCount - 1 do
  begin
    for j := 0 to StringGrid1.ColCount - 1 do
    begin
      if StringGrid1.Cells[j, i] = '' then
        StringGrid1.Cells[j, i] := '0';
    end;
  end;
end;

you can easily translate this into unigui

uses
  ComObj;

function Xls_To_StringGrid(AGrid: TStringGrid; AXLSFile: string): Boolean;
const
  xlCellTypeLastCell = $0000000B;

Is there sample how to do this with drug and drop XLS file in browser?
