```js
{
  "csv": {
    "field": "my_field",
    "target_fields": ["field1", "field2"]
  }
}
```

If the `trim` option is enabled then any whitespace in the beginning and in the end of each unquoted field will be trimmed. For example with configuration above, a value of `A, B` will result in field `field2` having value `{{nbsp}}B` (with space at the beginning). If `trim` is enabled `A, B` will result in field `field2` having value `B` (no whitespace). Quoted fields will be left untouched.
