[!["Buy Me A Coffee"](https://www.buymeacoffee.com/assets/img/custom_images/orange_img.png)](https://www.buymeacoffee.com/prongbang)

## Install

```shell

go get github.com/prongbang/csvx

```

## Define struct for Convert

Add `header` for mapping in csv header and `no` start with 1 for sort header

```go

type MyStruct struct {

    Name  string `json:"name" header:"Name Space" no:"2"`

    ID    int    `json:"id" header:"ID" no:"1"`

    Other string

}

```

## Support type

- `int`, `int8`, `int16`, `int32`, `int64`

- `string`

- `float64`

## Using for Convert

```go

m := []MyStruct{

    {ID: 1, Name: "N1"}, 

    {ID: 2, Name: "N2"}

}

csv := csvx.Convert[MyStruct](m)

```

## Result

```csv

"ID","Name Space"

"1","N1"

"2","N2"

```

## Define struct for Parse

Add `header` for mapping in csv header

```go

type Struct struct {

	ID   string `header:"ID"`

	Name string `header:"Name Space"`

}

```

## Using for Parse

```go

rows := [][]string{

    {"ID", "Name Space"},

    {"1", "Name1"},

    {"2", "Name2"},

    {"3", "Name3"},

    {"4", "Name4"},

}

s := csvx.Parser[Struct](rows)

```

## Result

```json

[

  {"ID":"1","Name":"Name1"},

  {"ID":"2","Name":"Name2"},

  {"ID":"3","Name":"Name3"},

  {"ID":"4","Name":"Name4"}

]

```
