Try using excel data reader from Codeplex and check how it returns the data set. Also try to manipulate dataset based on your need
I have a Gridview that reads the DataSource from an EntityDataSrouce.
Now I want to convert the EntityDatasource of the gridview to DataTable so I can export it the Gridview as an Excel file.
You do not need to convert it to DataTable just to export. You can do it by gridview self.
Look at this link:

In this article, the author uses a utility class that export it to .xls file, so, you can download it, add on your project and use like the sample.

I want to check the alignment info of each cell. If a cell is left-aligned, I will pick data from those left-aligned cells.
How can I do that?
Sorry It is a stupid question but I really need it.
Thanks
You can't do that with Excel OleDb provider; cell alignment isn't exposed. The OleDb provider makes the Excel spreadsheet mimic a database table and database columns don't have alignment.
You'll have to use Excel interop if you need to that. See this question for help on that.
I have the excel sheet, I want to keep it as datasource to the gridview. gridview will be editable so whatever the data updated sholud be write to again in excel sheet with respected location in sheet.
How can I do this?
You could use the Jet driver to select from the spreadsheet via OLEDB. Your spreadsheet will need to be laid out in a table-like fashion, and you can have some painful problems with type guessing, but this may work for your situation.
