In my application I want the user to upload an excel file and then he should be able to view the contents of the excel file with the web page where he uploaded. Is there any way to achieve this?
You can maybe save the excel sheet as a csv file, then upload, read the contents and write it on to the page. More info here: read csv file from a location and display as html table

This opens the excel sheet in a new browser window. I am however not able to modify it.
any idea how it can that be done...
thanks in advance
When requesting a file from a server (like the Excel sheet), it is downloaded to your local computer. If you edit it there, your edits do not affect the Excel file on the server.
So editing it directly on the server using a browser is not possible.
You could add an upload functionality to your webpage where you can upload the changed excel file using <input type="file">. However this might get difficult because you would need to ensure that the uploaded file is the same as the original one.
If you want your users to be able to edit data on your webserver, you could save this data in a file, database etc. and provide a form to the users where they can edit the data.
