Is it possible to write an HTML string inside JSON?

Which I want to write like below in my JSON file:

        "html": "<h2class="fg-white">AboutUs</h2><pclass="fg-white">developing and supporting complex IT solutions.Touchingmillions of lives world wide by bringing in innovative technology </p>"

You should escape the characters like double quotes in the html string by adding "\"

eg: <h2 class=\"fg-white\">

Just encode html using Base64 algorithm before adding html to the JSON and decode html using Base64 when you read.

byte[] utf8 = htmlMessage.getBytes("UTF8");
htmlMessage= new String(new Base64().encode(utf8));


byte[] dec = new Base64().decode(htmlMessage.getBytes());
htmlMessage = new String(dec , "UTF8");

Converting a JSON Text to a JavaScript Object. A common use of JSON is to read data from a web server, and display the data in a web page. For simplicity, this can be demonstrated using a string as input. First, create a JavaScript string containing JSON syntax:

If using PHP, you could use json_encode()

Hope this helps :)

JSON HTML, Date objects are not allowed in JSON. If you need to include a date, write it as a string. You can convert it back into a date object later: Example. Converting JSON objects into strings can be particularly useful for transporting data in a quick manner.

One way is to replace the double quotes in the HTML with single quotes but using double quotes has become the standard convention for attribute values in HTML.

The better option is to escape the double quotes in json and other characters that need to be escaped.

You can get some more details about escaping here: Where can I find a list of escape characters required for my JSON ajax return type?

JSON.parse(), var obj = { name: "John", age: 30, city: "New York" };. Use the JavaScript function JSON.stringify() to convert it into a string. var myJSON = JSON  System.Text.Json.Utf8JsonWriter is a high-performance way to write UTF-8 encoded JSON text from common .NET types like String, Int32, and DateTime. The writer is a low-level type that can be used to build custom serializers.

After conversion, you can beautify JSON and download converted JSON  JSON or JavaScript Object Notation is a lightweight text-based open standard designed for human-readable data interchange. Conventions used by JSON are known to programmers, which include C, C++, Java, Python, Perl, etc. JSON stands for JavaScript Object Notation. The format was specified by Douglas Crockford.

Because JSON derives from JavaScript, you can parse a JSON string simply by invoking the eval() function. The JSON string needs to be wrapped by parenthesis, else it will not work! This is the #1 problem when programmers first start to manipulate JSON strings. That being said, DON'T do this!

  • I don't know much about JSON, but i think you should use escape sequences for quotes after class, " like \".
  • Please refer thorntech.com/2012/07/…
  • I have changed my code as below but still it is showing validation error in JSONLint validator [ { "id": "services.html", "img": "img/SolutionInnerbananer.jpg", "html": "<h2 class=\"fg-white\">AboutUs<\/h2><p class=\"fg-white\">we are pioneer in providing consulting, developing and supporting complex IT solution<\/p>" } ]
  • You sure? I just checked here: jsonlint.com and its saying that its a "valid JSON"
  • Ya. It is a valid JOSN. Thank You very much
  • If you echo ' " ' the content will be escaped automatically by PHP.

  • There is not "standard HTML format" that gets "violated" by using single quotes. Single quotes in HTML is perfectly valid HTML!
  • You're right, I was looking at it from a conventions perspective. The vast majority prefer to use double quotes for HTML attribute values. I've updated my answer to reflect this.
  • I've used single quotes in the html successfully when returned as a json string. It will validate as valid json as well.
  • wrapping around single quotes doesn't work if you want valid json object.
