How to convert this 'array'

Question

With FeedMe I'm importing some data and one of them I get is a complete array that is stored a plain text field.

This array is a bunch of car options what I want to add in a table like this:

{% set options = entry.optionsAndAccessoiries %}

output {{ options }} = ["Achterbank in delen neerklapbaar","Airbag bestuurder","Airconditioning","Anti-slipregeling","Antiblokkeersysteem","Centrale deurvergrendeling afstandbediend","Elektrisch bedienbare ramen voor","Elektrisch verstelbare buitenspiegels","Getint glas","Hoofdsteunen achter","Hoofdsteunen voor","In hoogte verstelbare bestuurdersstoel","Metallic lak","Middenarmsteun voor","Mistlampen voor","Radio\/CD speler","Startonderbreker","Stoelverwarming bestuurder","Stoffen bekleding","Stuurbekrachtiging","Trekhaak","Verstelbaar stuurwiel"]

{% set items = options %}

 <table>
  {% for row in items|batch(3, 'No item') %}
  <tr>
    {% for column in row %}
    <td>{{ column }}</td>
    {% endfor %}
  </tr>
  {% endfor %}
</table>

But this is causing an error:

array_chunk() expects parameter 1 to be array, string given

Who can help me out to point me in the right direction?

Sounds like your options simply need to be JSON decoded. Unfortunately, Twig doesn't ship with a json_decode filter, so you'll need a plugin – there are several that fit the bill over at StraightUpCraft.

Using the JSON Decode Filter plugin, here's how your code would look:

{% set options = entry.optionsAndAccessoiries|json_decode %}
