Yes, you have to install MSOffice.
You can also use OLEDB Provider for this.

This is code for u -

C#

string connectionString = String.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1;""", fileName);
string query = String.Format("select * from [{0}$]", "Sheet1");
OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connectionString);
DataSet ds = new DataSet();
dataAdapter.Fill(ds);
return ds;

Yes Microsoft Office needs to be installed in your machine. As for C# programming we needed to add a reference to excel and this visual studio can get only when components of Microsoft office is registered. While installing office all the components gets registered and we get reference of that registered component in our program.

MS Office does not just give you Excel, Word etc, but also the framework that allows data manipulation, import export, VBA etc.

It is necessary for it to be installed in order to have the functionality available for iis etc.
