Spreadsheet connection in vb web app

Question

My client wants their price list on their website. I'm trying to use the spreadsheet (.xlsx) as a data source so as to limit processing of the data before it appears on the website.

The site is running on IIS 7. The server is Windows Server 2008. I've updated the .NET Framework on it to 4.0 as well.

It doesn't have any Office packages installed on it, and I have a hunch thats where my problem lies, but I'd really like to be sure.

Heres the error text I'm getting:

System.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine. at System.Data.OleDb.OleDbServicesWrapper.GetDataSource(OleDbConnectionString constr, DataSourceWrapper& datasrcWrapper) at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection) at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OleDb.OleDbConnection.Open() at Products.Page_Load(Object sender, EventArgs e) in C:\\HostingSpaces\\webbuddies\\waterinc.webbuddies.co.za\\wwwroot\\Products.aspx.vb:line 14

Heres my code:

        daWater.Fill(dsWater, "Water")
        daJuice.Fill(dsJuice, "FruitJuice")
        daMix.Fill(dsMix, "MuffinMix")
        daMisc.Fill(dsMisc, "Miscellaneous")

        rptWater.DataSource = dsWater : rptWater.DataBind()
        rptJuices.DataSource = dsJuice : rptJuices.DataBind()
        rptMixes.DataSource = dsMix : rptMixes.DataBind()
        rptMisc.DataSource = dsMisc : rptJuices.DataBind()

        con.Close()
    Catch ex As Exception
        errorMessage = ex.ToString
        lblResponse.Text = "Could not connect to one or more data sources required to display the " & _
            "pricelist. Please contact the webmaster." & vbCrLf & errorMessage
        lblResponse.ForeColor = Drawing.Color.Red
    End Try
End Sub

EDIT 1
Since posting I have installed the 2007 office driver on the server from the link in the 1st answer, and I have modified my connection string as per the 2nd answer:

<connectionStrings>
    <add name="xlsx" connectionString="Provider=Microsoft.ACE.OLEDB.12.0; Data Source=App_Data/Pricelist.xlsx; Extended Properties=Excel 12.0 Xml; HDR=YES;"/>
</connectionStrings>

Answer 1

For XLSX file you need to modify the connection string like this.

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES";

Answer 2

You need to have the 2007 office driver installed for this to work.
