JSON Parsing issue

Writing a character importer. In the JSON of the imported character I am getting an error on a closing square bracket "]". I have dropped the JSON (after some inline repairs) to a parser , which says it is valid JSON. I already have code to handle the \t, it's just commented. Any suggestions? Error: SyntaxError: Unexpected token ] in JSON at position 3910 Code:       var token = getObj("graphic",selected[0]._id);       var character = getObj("character",token.get("represents"));       var herodesignerData = []; //    log(character);       var characterName = findObjs({type: 'attribute', characterid: character.id, name: 'name'})[0];       character.get("gmnotes", function(gmnotes) {         gmnotes = gmnotes.replace(/<[^>]*>/g, '');         gmnotes = gmnotes.replace(/&[^;]*;/g, '');         //gmnotes = gmnotes.replace(/\},\s{2,}\]/g, '\}\]');         //gmnotes = gmnotes.replace(/[^ -~]/g, '');         //gmnotes = gmnotes.replace('Other Attacks:', 'Other Attacks - 1/2 ');       log(gmnotes);         var hdJSON = JSON.parse(gmnotes); JSON: (Prettied up a bit for reading, Error

I think the root of the issue is likely in your preprocessing of the gmnotes text. If I remember correctly, you should call decode() (or maybe it was unescape() ?  This is all from memory...) on it first, then strip out the HTML tags, then the JSON.stringify should work. 

This is what I use in UniversalVTTImporter to strip down the gmnotes to just JSON: const importUVTTonGraphic = (token) => { let rawNotes = token.get('gmnotes'); let notes = unescape(rawNotes).replace(/(?:<[^>]*>|\\t| )/g,''); let data; try { data = JSON.parse(notes); } catch( e ){ return {error: "Universal VTT Data is missing or corrupt.", token}; }     /* ... */

Thanks, Aaron. I looked up decode and found a function you had over in the API Cookbook utility functions. Implemented that, removed the extraneous HTML tags (span, etc) and I was still getting the same error in the JSON parse. But the formatting in the log let me find the parse error (an invalid character) which turned out to be an extra trailing comma in the line  \"abort\":false}, so thanks for the assist.  - E
