First you need to make your array file. Open a blank notepad and paste in the following:
{
"c2array":true,
"size":[1,3,1],
"data":[
[
["sentence 1"],
["sentence 2"],
["sentence 3"],
["sentence 4"]
]
]
}
Just replace sentence 1 etc with your sentences. Then change the 1,3,1 part at the top so the 3 is equal to the number of sentences that you have -1.
When you're finished save the .txt file as .json
After you are finished with that, let me know and I'll show you how to put it into your project.
