I have 2D Array and values are being saved each in new line, is there way to save them just in one row? like this:
"aviabilityMatrix":[
[false,true,true,false,false],
[false,true,true,false,false],
[false,true,true,false,false],

Could store them as strings and then write some code to convert it, if it's really important.

  "Some Booleans as Strings": [
    "ttftfftft",
    "ftfftfttf"
  ],​
