Overview ¶

You can use flat struct data type to recieve the csv data.
This package are an extended version of encoding/csv package. See encoding/csv package : http://golang.org/pkg/encoding/csv/

Types ¶
type Reader ¶
A Reader reads records from a CSV-encoded file.
Example ¶
package main import ( "fmt" "strings" "time" "github.com/atotto/encoding/csv" ) func main() { csvtext := "Gopher,2,12.3,34.5,2020/01/01 12:20:02\nGhost,4,12.3,3.4e-05,2020/02/03 15:20:02" type Person struct { Name string Age int Height float32 Weight float64 CreateTime time.Time } var person = []Person{} r := csv.NewReader(strings.NewReader(csvtext)) r.SetTimeFormat("2006/01/02 15:04:05") r.SetTimeLocation(time.UTC) err := r.ReadStructAll(&person) if err != nil { return } fmt.Printf("%v", person) }
Output: [{Gopher 2 12.3 34.5 2020-01-01 12:20:02 +0000 UTC} {Ghost 4 12.3 3.4e-05 2020-02-03 15:20:02 +0000 UTC}]
func (*Reader) ReadStruct ¶
func (*Reader) ReadStructAll ¶
func (*Reader) SetTimeFormat ¶
func (*Reader) SetTimeLocation ¶ added in v0.1.3
type UnsupportedTypeError ¶
An UnsupportedTypeError is returned by Writer when attempting to encode an unsupported value type.
func (*UnsupportedTypeError) Error ¶
func (e *UnsupportedTypeError) Error() string
type Writer ¶
A Writer writes records to a CSV encoded file.
see encoding/csv package.
Example ¶
package main import ( "os" "time" "github.com/atotto/encoding/csv" ) func main() { type Person struct { Name string Age int Height float32 Weight float64 CreateTime time.Time } member := []Person{ {"Gopher", 2, 12.3, 34.5, time.Date(2020, 1, 1, 12, 20, 2, 0, time.UTC)}, {"Ghost", 4, 12.3, 0.000034, time.Date(2020, 2, 3, 15, 20, 2, 0, time.UTC)}, } w := csv.NewWriter(os.Stdout) w.SetTimeLocation(time.UTC) w.WriteStructAll(member) }
Output: Gopher,2,12.3,34.5,2020-01-01 12:20:02 Ghost,4,12.3,3.4e-05,2020-02-03 15:20:02
func (*Writer) SetTimeFormat ¶
func (*Writer) SetTimeLocation ¶ added in v0.1.3
func (*Writer) WriteStruct ¶
WriteStruct writes a single CSV record to w along with any necessary quoting. A record is a struct of flat structure.
func (*Writer) WriteStructAll ¶
WriteStructAll write
func (*Writer) WriteStructHeader ¶
