Extracting data from a tab-delimited file with JavaScript

Question

I'm trying to extract data from a data file that's tab-delimited (in some parts), and really seems like it's going to be a headache to work out (I reallw wish they could just have CSV-ed it).

Here's the data:

http://www.fededirectory.frb.org/FedACHdir.txt

Here's the format description:

I'd like to extract this data and store it in a database with serverside javascript, (ASP). Any ideas?
