This is an unofficial Node.js parser for electronic filings submitted to the Federal Election Commission.
This uses code from the Fech Ruby gem by Derek Willis and others, and the csv-parser module by Mathias Buus, Max Ogden and others. It uses header mappings contributed to by many and refined by Evan Sonderegger for fecfile.
