如何直接在delphi中处理excell文档的数据？
我想要在delphi中直接处理excell中的数据，包括直接读写它的cell，把内容写入数据库等操作。谢谢！

使用ole把excel文档打开，然后你就可以随意操作了。
别人的资料和代码，贴给你。

procedure TForm1.Button5Click(Sender: TObject);
var
ExcelApp,MyWorkBook,mysheet:Variant;
i :byte;
s: string;
begin
try
ExcelApp:=CreateOleObject('Excel.Application');
MyWorkBook:=CreateOleobject('Excel.Sheet');
//? MyWorkBook:=ExcelApp.workbooks.open('C:/Book1.xls');
except
on Exception do raise exception.Create('无法打开Xls文件，请确认已 经安装EXCEL')
end;
ExcelApp.Visible := true;
//? mysheet:=MyWorkBook.WorkSheets[1].name;

MyworkBook:=ExcelApp.workBooks.Add;

//在此处插入读数据库及写Excel文档的代码
//其中写Excel文档的关键语句如下：
Myworkbook.worksheets[1].range['A11'].Merge(True);
Myworkbook.worksheets[1].range['A12'].HorizontalAlignment := $FFFFEFF4;
MyWorkBook.WorkSheets[1].Cells[1,1].Value := 'YourTitle';

i := 2;
MyWorkBook.WorkSheets[1].Cells[i,1].Value := 'yourCaption1';
MyWorkBook.WorkSheets[1].Cells[i,2].Value := 'yourCaption2';
MyWorkBook.WorkSheets[1].Cells[i,3].Value := 'yourCaption3';
MyWorkBook.WorkSheets[1].Cells[i,4].Value := 'yourCaption4';
Myworkbook.worksheets[1].Range['A12'].Font.Color := clBlue;
Myworkbook.worksheets[1].Range['A11'].Font.Name := '隶书';
Myworkbook.worksheets[1].Range['A11'].Font.Size := 18;


i := 3;
table1.close;
table1.open;
table1.First;
while not table1.eof do begin
MyWorkBook.WorkSheets[1].Cells[i,1].Value := table1.FieldByName('au_id').AsString;
MyWorkBook.WorkSheets[1].Cells[i,2].Value := table1.FieldByName('royaltyper').AsInteger;
MyWorkBook.WorkSheets[1].Cells[i,3].Value := table1.FieldByName('au_ord').AsInteger;
MyWorkBook.WorkSheets[1].Cells[i,4].Value := table1.FieldByName('title_id').AsString;
Inc(i);
table1.Next
end;
ExcelApp.Visible := true;

s := 'A3'+ IntToStr(i-1);

//设定字体. 栏宽等
s := 'A1'+ IntToStr(i-1);
Myworkbook.worksheets[1].Columns[1].ColumnWidth := 20;
Myworkbook.worksheets[1].Columns[4].ColumnWidth := 25;
Myworkbook.worksheets[1].Rows[1].RowHeight := 50;
Myworkbook.worksheets[1].Rows[1].VerticalAlignment := $FFFFEFF4;

Myworkbook.worksheets[1].Range.Font.Name := '仿宋';
s := 'A2'+ IntToStr(i-1);
Myworkbook.worksheets[1].Range.Borders.LineStyle := 1;
//页面设置
MyworkBook.WorkSheets[1].PageSetup.CenterHorizontally := true;
Myworkbook.worksheets[1].pagesetup.PrintTitleRows := 'A1';
try
MyWorkBook.saveas('c:/' + Edit1.Text + '.xls');
MyWorkBook.close;
except //当存为一个已有的文档而又不覆盖时将
MyWorkBook.close; //产生一个例外
end;
ExcelApp.Quit;
ExcelApp:=Unassigned; //释放VARIANT变量

end;
