Now i convert the json format and use **WithMultipleDocs** option, it works
well.
```go
func TestReadJson(t *testing.T) {
file, err := os.Open("/home/data/180000.json")
if err != nil {
fmt.Println("open json:", err)
}
defer file.Close()
content, err := io.ReadAll(file)
if err != nil {
fmt.Println("read file:", err)
}
var jsonData []map[string]interface{}
err = json.Unmarshal(content, &jsonData)
if err != nil {
fmt.Println("Unmarshal failed:", err)
}
schema := arrow.NewSchema([]arrow.Field{
{Name: "instruction", Type: arrow.BinaryTypes.String, Nullable:
true},
{Name: "input", Type: arrow.BinaryTypes.String, Nullable: true},
{Name: "output", Type: arrow.BinaryTypes.String, Nullable:
true},
}, nil)
mem := memory.NewCheckedAllocator(memory.DefaultAllocator)
var recs []arrow.Record
for _, obj := range jsonData {
bytes, err := json.Marshal(obj)
if err != nil {
fmt.Println("Marshal failed:", err)
}
rec, _, err := array.RecordFromJSON(mem, schema,
strings.NewReader(string(bytes)), array.WithMultipleDocs())
recs = append(recs, rec)
}
fmt.Println("value -", recs[0].Column(0))
fmt.Println("value -", recs[0].Column(1))
fmt.Println("value -", recs[0].Column(2))
}
```
