unable to convert string to json using JSON.parse()

Question

json string:

str = "{'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/default.aspx',
'Title': 'Apply Online'},{'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/login.aspx',
'Title': 'Login'},{'Link': 'media/pdf/details/all-india-govt-jobs/other-all-india-govt-jobs/8588011698.pdf',
'Title': 'Notification '},{'Link': 'http://www.powergridindia.com/', 'Title': 'Official Website'}"

expecting:

json = {'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/default.aspx',
'Title': 'Apply Online'},{'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/login.aspx',
'Title': 'Login'},{'Link': 'media/pdf/details/all-india-govt-jobs/other-all-india-govt-jobs/8588011698.pdf',
'Title': 'Notification '},{'Link': 'http://www.powergridindia.com/', 'Title': 'Official Website'}

i am trying with JSON.parse(str); it gives me error:

VM267:1 Uncaught SyntaxError: Unexpected token ' in JSON at position 1
at JSON.parse (<anonymous>)
at <anonymous>:1:6

How can i convert string to pure json.

please have a look into this.

Your Json is not correct. your trying to convet some kind of Array of Jsons but your not putting it inside Array. — Talg123

JSON.parse expects a well formed string. JSON data is written as name/value pairs. A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value (in double quotes if its a string value).

In addition, it looks like you're attempting to describe a collection of objects, so you should wrap it all inside an array... (note i'm using a `` ES2015 string, that allows multiline strings)

const str = `[{
    "Link": "https://careers.powergrid.in/CCBaclogVacancy2018/c/default.aspx",
    "Title": "Apply Online"
},
{
    "Link": "https://careers.powergrid.in/CCBaclogVacancy2018/c/login.aspx",
    "Title": "Login"
},
{
    "Link": "media/pdf/details/all-india-govt-jobs/other-all-india-govt-jobs/8588011698.pdf",
    "Title": "Notification "
},
{
    "Link": "http://www.powergridindia.com/",
    "Title": "Official Website"
}]`;
console.log(JSON.parse(str)[0].Title); // Apply Online

Your json is invalid.

single quote should be double quote
objects should be wrapped by [] which indicate array

so to make it valid json, wrap objects with brackets and replace all single quote, and then parse it.

str = `[{'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/default.aspx',
'Title': 'Apply Online'},{'Link': 'https://careers.powergrid.in/CCBaclogVacancy2018/c/login.aspx',
'Title': 'Login'},{'Link': 'media/pdf/details/all-india-govt-jobs/other-all-india-govt-jobs/8588011698.pdf',
'Title': 'Notification '},{'Link': 'http://www.powergridindia.com/', 'Title': 'Official Website'}]`

json = JSON.parse(str.replace(/'/g, '"'))
console.log(json)

str = "what 'ever'";
str = str.replace(/'/gi,'"')

this is the way to replace all with regexp and replace()

You are missing the outermost wrapper for whatever array you have going on here. Also double quotes are the standard in json

Try wrapping your fields.

`{
   "items": [
      {
       "Link": "https://careers.powergrid.in/CCBaclogVacancy2018/c/default.aspx",
       "Title": "Apply Online"
      }, {
        "Link": "https://careers.powergrid.in/CCBaclogVacancy2018/c/login.aspx",
        "Title": "Login"
      }, {
        "Link": "media/pdf/details/all-india-govt-jobs/other-all-india-govt-jobs/8588011698.pdf",
        "Title": "Notification"
      }, {
        "Link": "http://www.powergridindia.com",
        "Title": "Official Website"
      }
    ]
}`

Typo! You forgot opening the first object on the items array

Sampson Crowley Over a year ago

Yeah. I'm doing this from a phone, so i have to submit to preview

sminutoli Over a year ago

Traditional strings doesn't support multiline, you should use `` or the old-nasty + after each line

Sampson Crowley Over a year ago

@sminutoli yes that is true, I'm just trying to make the format more obvious. You'd have to remove the whitespace in actual use
