Looking for web based reporting tool

I have been requested to develop a project reporting tool which is nowadays based in Excel spreadsheets. Basically I have one project status spreadshet from every project manager which needs to be consolidated in a single spreadsheet to be sent to high management for the project performance discussions.

I am studying alternatives and I believe that creating an external/unique database is the best choice, however I need some tools to help me creating the reports.

I am thinking about MS Access but I am not handling very well the Web publishing process.

Does anyone know how to create reports that could be easily accessed remotely via an intranet page and which could be stored in a central database?

Many thanks
