How to replace?

[Joep]

Hi all,

I'm working on a Vestaboard API integration. And so far everything is working fine but now i want to replace the status (layout) to a readable string so i can use it in my visualization.

The Vestaboard returns the layout like this:

Code:

{
  "currentMessage": {
    "layout": "[[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,8,5,12,12,15,0,23,15,18,12,4,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]]",
    "id": "172c7808-52db-4eb9-9ecf-505bd00436bc"
  }
}

  And i created a JSON string of all numbers and their corresponding characters:

Code:

characters = '{"0":" ","1":"a","2":"b","3":"c","4":"d","5":"e","6":"f","7":"g","8":"h","9":"i","10":"j","11":"k","12":"l","13":"m","14":"n","15":"o","16":"p","17":"q","18":"r","19":"s","20":"t","21":"u","22":"v","23":"w","24":"x","25":"y","26":"z","27":"1","28":"2","29":"3","30":"4","31":"5","32":"6","33":"7","34":"8","35":"9","36":"0","37":"!","38":"@","39":"#","40":"$","41":"(","42":")","44":"-","46":"+","47":"&","48":"=","49":";","50":":","52":"\'","53":"\\"","54":"%","55":",","56":".","59":"/","60":"?","62":"°","63":"red","64":"orange","65":"yellow","66":"green","67":"blue","68":"purple","69":"white","70":"black","71":""}'

So now i need a script that convert the Vestaboard "layout" with the characters string.

Many thanks for your help.
