Module for intelligently analyzing and merging spreadsheet data

[nysus]

I want to handle lots of data, mostly from spreadsheets and csv files. I'm currently using Spreadsheet::Read to parse the data, which is great because it can handle different formats.

I want to take things a step further though and be able to merge data that may exist across many different spreadsheets where columns may/may not be in the same order or have a different name or maybe have no name at all or maybe not even exist. So, for example, it might identify a column full of phone numbers and ask me which column of existing data I would like to assign it to similar to the way I've seen this done through a web interface for uploading contact information. The script would also intelligently dedup and merge new data with existing data, or at least assist in that process, as well.

Before I write this myself, I'm wondering if there might be a suite of tools that already tackles this problem. Seems like it is a common enough problem.
