var
excelx,excely:string;
ExcelApp:Variant;
workBook:OleVariant;
excelRowCount,excelColumnCount:longint;
i,j,row,row1:integer;

begin
row1:=1;

dlgOpen1.Filter:='Excel文件|*.xls|*.xlsx';
if dlgOpen1.Execute then

excelRowCount:=ExcelApp.ActiveSheet.UsedRange.Rows.count;
row:=1;
pb1.Max:=excelRowCount;

for i := 1 to excelRowCount do
begin
excelx:= excelapp.Cells[i,1].Value;
excely:=ExcelApp.cells[i,2].value;
if (excelx<>'') and (excely<>'') then
begin
if strngrd1.RowCount<i then
strngrd1.RowCount:=strngrd1.RowCount+1;
strngrd1.Cells[0,row]:=IntToStr(row);
strngrd1.Cells[1,row]:=excelx;
strngrd1.Cells[2,row]:=excely;
