First, replace the surrounding apostrophes ' with double quotes ". Otherwise, JSON won't work with the file.
Next, you need to modify the file so that it begins with an open bracket [, ends with a closing bracket ], and all the words are separated by a comma.
So the first few words of your file would look like this
["A",
"A'",
"A-",
"A&M",
"A&P",
"A.",
"A.A.A."]
Now all you need to do to load your dictionary in is to call the load method on the array.
MyArray.Load("Dictionary.json")
With multiple letters like you have, something like this would do.
(just typing this in, haven't actually tested it yet.
dictionary as String[0,0]
dictionary.length = 26
letters as String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ""
for i = 0 to 25
dictionary[i].load(Mid(letters,i+1,1)+"-Words.json")
next
randomLetter = Random(0,25)
randomWord = Random(0,dictionary[randomLetter].length)
do
Print ( dictionary[randomLetter,randomWord] )
sync()
loop
