For example, if you must use some XML from another application, but you cannot determine which XML schema the data will follow, you can do so
Excel in the machine; reading Excel documents directly can reduce the user's operating burden; the amount of data per time is not too large (1000), so speed is not a problem; using OLE to read Excel files directly can make your application more powerful!
