Where do I begin...
You have a mess with quotation marks:
["arbor, arboris","ambulÅ, ambulÄre","commÅtus, commÅtÄ, commÅtum","diÅ«","e, ex",quÄ«dam, quaedam, quoddam,"nec/neque"],
You have different number of elements in each row.
You have specified incorrect size in JSON.
And finally, your JSON file is saved in some weird code page 1200. Even if you format your JSON string properly, C2 can't load it from this file. Try saving your json file in Notepad with UTF-8 encoding.
Use example from this tutorial to see how JSON should be formatted for string values:
