Zions Bank will only let me download crappy little CSV files. Quickbooks wants nicely formatted IIF files. This little guy does the translation.
Run like so node zions.js download.csv and watch the output in result.iif.
I haven't spent any time making this prettier than it has to be. I intend to run this sucker once a month, copy the result.iif file out to another part of the filesystem, and forget about it for another month.
