The described scenario can be achieved using the Spreadsheet component of the Kendo UI suite. Here is an example that demonstrates similar scenario to the one described in your last reply. The example demonstrates how we can upload a CSV/Excel file. The file is sent to the server and then opened in the Spreadsheet component.
This Spreadsheet / DataSource binding demo demonstrates how we can load file from the server, edit it and save the changes.
You can combine the above two demos and achieve the desired scenario. Depending on the backend used in the application, you can read the uploaded and edited file and save its data in a database.
