JSON Formatter Online Tool

This online json formatter tool helps you to format raw JSON string so it can easily be read by human being.

Simply put, JSON can convert a set of data represented in a JavaScript object into a string, then you can easily pass the string between functions, or pass the string from the web client to the server in an asynchronous application. This looks a bit odd, but JavaScript makes it easy to interpret, and JSON can represent a lot more complex data structure than "name/value pairs." For example, you can represent arrays and complex objects, not just simple lists of keys and values.

JSON is simpler to read than XML, JSON use a simper grammar and less space wasted in the outside structure.

JSON is much simpler to parse than XML. JSON is very well compatible with JavaScript, while parsing XML needs complex XPath.

Google has a hard time understanding the content of the page. However, you can help us by providing Google with clear clues about what the page means by including structured data on the page. Structured data is a standardized format used to provide information about a page and to categorize the content of the page; for example, on the recipe page, what is the ingredient, cooking time and temperature, calories, and so on.

Structured data (for example JSON-LD), in simple terms, is what we tell Google Crawler to parse. For an article, it has a title, author, release time, content, and possibly a cover image. These content can be displayed directly to search engines in a way that Google's crawlers can understand. And when you decide to provide Google with more friendly data, Google will also provide a more friendly experience for your potential users.
