Golang Convert CSV Records to Dictionaries using Header Row as Keys

csvtomap.go

// CSVToMap takes a reader and returns an array of dictionaries, using the header row as the keys
func CSVToMap(reader io.Reader) []map[string]string {
	r := csv.NewReader(reader)
	rows := []map[string]string{}
	var header []string
	for {
		record, err := r.Read()
		if err == io.EOF {
			break
		}
		if err != nil {
			log.Fatal(err)
		}
		if header == nil {
			header = record
		} else {
			dict := map[string]string{}
			for i := range header {
				dict[header[i]] = record[i]
			}
			rows = append(rows, dict)
		}
	}
	return rows
}

Nice

In line no 14, i think we should change header == nil to if len(header) == 0

The we should declare it as a slice i guess
header := make([]string,0)

This method is really awesome!

Nice work! I was working with 2 colums csv and found here. I used same made a function for one map[type]type
It is here
