Csv File Compare
-
I'm looking at creating a CSV (or, in general, delimited) file compare tool. Using an everyday diff tool is OK, but I would like to get results in terms of columns, i.e. I want to highlight columns added or delete, and just make the user experience a little better for the testers for a mammoth test project I'm embarking on. Where can I find out more about compare algorithms?

It hasn't been, due to other month-end pressures at work, but I've just found a wikipedia article on the algorithm used by diff. It's based on the Longest Common Sequence problem, but it's now 03:40, and it's a little difficult to understand.

Have you considered starting with an Open Source diff utility [like WinMerge - www.winmerge.org] or the sample diff tool on this site [www.codeproject.com/tools/difftool.asp]?
