I'm learning Guide, and I've been able to parse an array of objects...

AmpScript:

    set @json = '[{"voucher":"123456789"}, {"voucher":"234567890"}]'

Guide:

    	{{.dataobject JsonVar type=variable source=@json maxrows=20}}
		   {{.data}}
		        {"target":"@json"}
		   {{/data}}
		{{/dataobject}}
		{{#each JsonVar}}
		   <p>{{voucher}}</p>
		{{/each}}

Returns:

    123456789
    234567890

But what if I want to return the same output, but instead from a simpler array?

    set @json = '["123456789", "234567890"]'

I've tried everything I can find here, and in the docs, with no luck so far. Any help would be greatly appreciated!
