Citi CSV Converter

Converters CSV statements from Citi Bank Credit Card into a format that personal finance apps can understand.

Usage example:

package main

import (
	"encoding/csv"
	"log"
	"os"

	cc "github.com/davidjohngee/citicsvconverter"
)

func main() {
	data, err := os.Open(os.Args[1])
	if err != nil {
		log.Fatalf("cannot read csv: %v", err)
	}
	defer data.Close()

	// Let's parse them datas
	output, err := cc.YnabParser(data)
	if err != nil {
		log.Fatalf("couldn't parse csv file: %v", err)
	}

	// Build new CitiCSV
	w := csv.NewWriter(os.Stdout)

	// Get CSV
	csv, err := cc.YnabToCSV(output)
	if err != nil {
		log.Fatalf("Create CSV file: %v", err)
	}

	// We now build a writer func
	w.WriteAll(csv)

	if err = w.Error(); err != nil {
		log.Fatalln("error writing csv:", err)
	}
}

Build the code, then run:

go build
./app testdata.csv
