I have a JSON file and i am getting the json content which may contain new lines in it. Now i am facing a problem. I am getting the below error :

Unexpected token ↵ in JSON at position 9

Note: the error message says specificaly this symbol: '↵'. What does this mean?

My JSON:

{"T":". 
^00:00:43^2008-09-11 12:00:00.0"}

But if i remove the new line (not sure if its a new line or a tab space no matter what i am facing this issue even if its a tab space or new line. It works fine with normal space.). Below is the modified JSON and it looks good.

Modified JSON:

 {"T":".^00:00:43^2008-09-11 12:00:00.0"}

I have tried to follow similar threads like here and here and some similar threads. but nothing works even after applying those. Any help is appreciated here please.

This is one the solution i have tried:

var jsonString = JSON.stringify(data).replace(/(\r\n|\n|\r)/gm,"");

Is there anyway to detect these linebreaks and tab spaces and remove them?

• javascript
• jquery
• json

• About the ↵, it's a symbol used to visualize a newline. – Luka Čelebić Commented Jan 4, 2018 at 2:37
• @PredatorIWD so in this case its teh new line which is causing the problem in the jsonstring? – Stack Acc Commented Jan 4, 2018 at 2:38
• What does yourString.charCodeAt(9) show? – Barmar Commented Jan 4, 2018 at 2:38
• I believe in the above JSon 8th char is space and 9th is a new line here..I tried to replace new lines with normal space but thats not working either. @Barmar. So just trying to take suggestions here – Stack Acc Commented Jan 4, 2018 at 2:39
• 1 Post your code, otherwise we're just guessing at what you might be doing wrong. – Barmar Commented Jan 4, 2018 at 2:42

You shouldn't be calling JSON.stringify(). That will convert the newlines in the string to literal \n, which won't be matched by the escape sequences in the regexp. Just do the replacement directly on the bad data.

var data = `{"T":". 
^00:00:43^2008-09-11 12:00:00.0"}`;
var jsonString = data.replace(/(\r\n|\n|\r)/g,"");
var object = JSON.parse(jsonString);
console.log(object);

This worked for me:

var jsonString = data.replace(/[\n\r\t]/g,"");

That is not a valid JSON value. If you refer to https://www.json/, newline, carriage returns and etc will need to be included in the value itself.

There is no way to modify because the parser already throws the error.

The only solution I can think of is for the author of the JSON file to amend their value like your Modified JSON or if they want to preserve that newline,

{"T":".\n^00:00:43^2008-09-11 12:00:00.0"}
