parsing incomplete json

parseIncompleteJSON.js

function parseIncompleteJSON(jsonString, stopIndex) {
    try {
        return {
            json: JSON.parse(jsonString),
            stoppedAt: stopIndex
        };
    } catch (e) {
        return parseIncompleteJSON(jsonString.substring(0, jsonString.length - 1), jsonString.length - 1);
    }

}

For what it's worth, this may cause a stack overflow for large JSON files.

Clever, but: Uncaught RangeError: Maximum call stack size exceeded

hi @dionyziz , @franciskim
try this one:

let str = [{ "json": "incomplete"}, {"json": "partially complete"};

if (str.indexOf('[') === 0 || str.indexOf('{') === 0) {
str = parseIncompleteJSON(str.slice(0, str.lastIndexOf('}') + 1));
}

function parseIncompleteJSON (jsonString, i = 0) {

if (jsonString[0] == '[' && i == 0) { // agar json array of string hai to first time srf ']' lagay ga
  jsonString += ']'; 
} else if (jsonString[0] == '[') {
  jsonString = jsonString.slice(0, jsonString.length - 1).concat('}', ']');
} else {
  jsonString += '}';
}

if (i == 10) { 
  return jsonString;
}

try {
  return JSON.parse(jsonString);
} catch (e) {
  return parseIncompleteJSON(jsonString, ++i);
}
