Working on taxes and bills and such online-- I'm able to download my complete transaction history in a couple of different formats. There is a quicken .QIF format file that I actually like a lot-- I have to do some editing in a hex editor, but I can then bring it into excel. From there I can annotate what the individual transactions are for.
I should probably write a transcoding filter. It's a pretty simple structure-- it's a flat-field record structure that's an open format; the only trick is that each transaction record doesn't necessarily have the same fields.
