Tools to integrate (hundreds) of spreadsheets as RDF

I am also interested in integrating healthcare data published by the CDC.  Unfortunately, it comes as nearly 200 separate spreadsheets:

The only thing I am aware of that is designed to keep large numbers (potentially hundreds) of spreadsheets continuously integrated and in sync across an enterprise, each independently curated,  is Anzo by Cambridge Semantics.   Most of the other tools I am aware of do not do real-time updating of the RDF model from the CSV model, and are one-off conversions, so if you have more than one spreadsheet to update, it will be time consuming.

For one-off conversion Google Refine is quite easy to get started.  It has a great deal of data cleaning facilities for noisy or illogical data.  With its RDF extension you have *automated* data reconciliation  with outside linked data sources of your choice as DBpedia. This is  a feature I have not seen with any other conversion tool.    It does not do visualization, but there are plenty of desktop applications that do this very well.

Any other suggestions for any other 'pipeline' tools to keep CSV and RDF in sync which are (1) currently maintained and (2) have sufficient documentation and examples of importing and converting CSV to RDF?

What are some recommended simple "probably stand alone or work on one machine" utilities for converting spreadsheet data to RDF.  And then once that file is on disk, to visualize it as a graph?
This would be for HL7 and CIMI where we'd be entering "clinical models" directly into a spreadsheet, and then want to compare models made by different people.
