Keyword Software For Keyword Filtering(or applying negative lists)?

[svakanda]

I am working on gathering keyword lists for a PPV campaign. What is good software for managing large lists of 10k+? I need to be able to run negative filters, and ability to apply regex type formatting find & replace is helpful too!

thoughts?
