Parse Open Financial Exchange (OFX) files into a usable data structure.

For details on the OFX file format, download the latest specification from http://www.ofx.org/downloads.html

• Work in the browser (no native code dependencies)
• Have as small a footprint as possible (minimize dependencies)
  • Currently, xml2js is the only dependency and it may be removed in the future.
• Parse only, no serialization
• Make no attempt to support pre-ES6 runtimes

This is based on node-ofx, modified to be a pure-JavaScript implementation (so it works in the browser as well as in node.js) and to offer a promise-based API. Due to different goals and a different XML parser being used, it is not API-compatible and is probably slower.

Example usage:

import {parse as parseOFX} from 'ofx-js';

const ofxString = readFile("bank-statement.ofx");

parseOFX(ofxString).then(ofxData => {
    const statementResponse = ofxData.OFX.BANKMSGSRSV1.STMTTRNRS.STMTRS;
    const accountId = statementResponse.BANKACCTFROM.ACCTID;
    const currencyCode = currencyCode = statementResponse.CURDEF;
    const transactionStatement = statementResponse.BANKTRANLIST.STMTTRN;
    // do something...
});
