I want to set number format for food_json[price] and drink_json[price]. If fields defined as a following jsonable. How to define an accessor from doc https://octobercms.com/docs/database/mutators#accessors-and-mutators.

food_json[name]:
    label: Name
    type: text
food_json[option]:
    label: Option
    type: text
food_json[price]:
    label: Price
    type: number
drink_json[name]:
    label: Name
    type: text
drink_json[option]:
    label: Option
    type: text
drink_json[price]:
    label: Price
    type: number

I try following but It doesn't work.

public function getFoodJsonPriceAttribute($value)
{
    return number_format($value);
}

public function getDrinkJsonPriceAttribute($value)
{
    return number_format($value);
}

I also try following but It doesn't work too.

public function getFoodJsonAttribute($value)
{
    return number_format($value->price);
}

public function getDrinkJsonAttribute($value)
{
    return number_format($value->price);
}

Solved with json_decode and json_encode.

public function getFoodJsonAttribute($value)
{
    $value = json_decode($value);
    $value->price = number_format($value->price);
    return json_encode($value);
}

public function getDrinkJsonAttribute($value)
{
    $value = json_decode($value);
    $value->price = number_format($value->price);
    return json_encode($value);
}
