Simple Go utilities for reading CSV files into arrays or maps.

Installation

go get github.com/dracory/csvutils

Usage

ToArrays

Reads a CSV file and returns an array with each line as an array of strings.

package main

import (
    "fmt"
    "log"
    "github.com/dracory/csvutils"
)

func main() {
    records, err := csvutils.ToArrays("data.csv")
    if err != nil {
        log.Fatal(err)
    }

    // records[0] contains headers
    // records[1:] contains data rows
    for _, row := range records {
        fmt.Println(row)
    }
}

ToMaps

Reads a CSV file and returns an array of maps using the header row as keys.

package main

import (
    "fmt"
    "log"
    "github.com/dracory/csvutils"
)

func main() {
    // Optional: replace header names
    replacements := map[string]string{
        "First Name": "first_name",
        "Last Name":  "last_name",
    }

    records, err := csvutils.ToMaps("data.csv", replacements)
    if err != nil {
        log.Fatal(err)
    }

    for _, row := range records {
        fmt.Printf("Name: %s %s\n", row["first_name"], row["last_name"])
    }
}

Features

• ToArrays - Returns CSV as [][]string for raw access
• ToMaps - Returns CSV as []map[string]string with header-based keys
• Header trimming and name replacement support
