I got problem. I have this JSON automatically generated by Open Flash Chart php library. The problem is, OFC report JSON Parse Error [Syntax Error] while test result using http://www.jsonlint.com/ report that my JSON is fine. But, w3c parser report error too:(
Any help?
Here's the JSON:
{
"title": "Followers Trend",
"elements": [
{
"type": "area_hollow",
"fill-alpha": 0.35,
"values": [
],
"colour": "#5B56B6",
"text": "Followers",
"font-size": 12
}
],
"x_axis": {
"colour": "#A2ACBA",
"grid-colour": "#D7E4A3",
"offset": false,
"steps": 4,
"labels": {
"steps": 2,
"rotate": "vertical",
"colour": "#A2ACBA",
"labels": [
]
}
},
"x_legend": {
"text": "Week Trend (2009-08-17 - 2009-08-24)",
"style": "{font-size: 20px; color: #778877}"
},
"y_axis": {
"min": 0,
"max": 150,
"steps": 30
}
}

When it detects invalid JSON, it throws a JSON Parse error. For example, one of the most common typos or syntax errors in JSON is adding an extra comma separator at the end of an array or object value set. Notice in the first few examples above, we only use a comma to literally separate values from one another.
The most common way to handle JSON parse error is using try-catch block. If the JSON string is valid, it will return a JavaScript object. If the JSON string is invalid, it will throw a SyntaxError.
Follow these steps to resolve your invalid JSON formatting error. Verify that the service account credentials are in a valid JSON format. Tip: An online JSON formatter can identify problems with the JSON format. If the error persists, generate a new service account credentials key.
Example - Parsing JSONUse the JavaScript function JSON.parse() to convert text into a JavaScript object: const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}'); Make sure the text is in JSON format, or else you will get a syntax error.
A few things I learned while playing with JSON is:
If you have validate the JSON on various JSON validation services and the result is GOOD. But, when you failed to eval it, try to wrap your JSON using ( and ) => ({jsondata})
var json = eval( "(" + jsonString + ")" );
NEVER build the JSON yourself. It's a gate to failure. Always use official or popular JSON library (depending on your language). For example:
