CSV Transaction Converter for rabobank-csv-parser (Rabobank)

After coding rabobank-csv-parser to parse my bank's CSV transaction files, I was left with a situation where the column named didn't match up with my Mongo database schema. So I built this module to convert a row from rabobank-csv-parser to a row which I can add to Mongo.

In addition to converting the row into another row structure it also add a _hash key which is the SHA256 hash for the row. I am using this hash to avoid inserting a mutation multiple times.

The module is designed to be piped to from rabobank-csv-parser.

Install

npm i rabobank-csv-converter

Usage

Example code

I am using csv-streamify to pre-parse the CSV file.

const fs = require('fs')
const CSVStreamify = require('csv-streamify')
const RaboCSVParser = require('rabobank-csv-parser')
const RaboConverter = require('rabobank-csv-converter')

const csvParser = CSVStreamify()
const raboParser = new RaboCSVParser()
const raboConverter = new RaboConverter({
  bank: 'rabobank', // corresponds to the _id of the Bank documents
  account: 'NL08RABO2952747327', // corresponds to the _id of the Account documents, used if the row doesn't specify one
  currency: 'EUR' // sets a default currency, used if the row doesn't specify one
})

// A `data` event is emitted for each row
raboConverter.on('data', function (row) {
  // `data` is a Buffer, so we first convert it to JSON
  row = JSON.parse(row.toString())

  // Do what you want with it - displaying it, for example
  console.log(row)
})

// Pipe a file stream through csv-streamify, rabobank-csv-parser and then this module
fs.createReadStream('transactions.txt').pipe(csvParser).pipe(raboParser).pipe(raboConverter)

Example output

The data in this example output has been faked (obviously). The ouput is a single row (or one data event).

Depending on the keys in the original row there may be more or fewer keys.
