This library provides methods to read and write CSV data into and from Go structs.

Decoding

Given the following CSV data:

Name,Age,Height
Alice,25,5.7
Bob,24,5.9

You could decode the data into structs like so:

f, _ := os.Open("path/to/your.csv")
defer f.Close()
type Person struct {
	Name string
	Age int
	Height float64
}
var p Person
d := csvstruct.NewDecoder(f)
for {
	if err := d.DecodeNext(&p); err == io.EOF {
		break
	} else if err != nil {
		// handle error
	}
	fmt.Printf('%s's age is %d\n", p.Name, p.Age)
}

Encoding

Similarly, given structs, you can generate CSV data.

people := []Person{{"Carl", 31, 6.0}, {"Debbie", 27, 5.3}}
e := csvstruct.NewEncoder(os.Stdout)
for _, p := range people {
	if err := e.EncodeNext(p); err != nil {
		// handle error
	}
}

Struct tags are supported to override the struct's field names and ignore fields. See the GoDoc for more information and tests for more examples.
