CSV

One of the most common ways a file is structured is as a comma-separated value. This is a clear text file that contains data, which is basically represented as rows and columns. Frequently, these files are used to exchange data. A CSV file has a simple structure. Each piece of data is separated by a comma and then a new line for another record. An example of a CSV file would be as follows:

firstName, lastName, age
Celina, Jones, 18
Cailyn, Henderson, 13 
Cayden, Smith, 42

• You will, at some point in your life, come across CSV files as they are very common. The Go programming language has a standard library that is used for handling CSV files: encoding/csv:

package main
import (
  "encoding/csv"
  "fmt"
  "io"
  "log"
  "strings"
)
func main() {
  in := `firstName, lastName, age
Celina, Jones, 18
Cailyn, Henderson, 13 
Cayden, Smith, 42
`
  r ...
