What is JSON?

  • JSON (JavaScript Object Notation) is a lightweight data-interchange format.
  • It is easy for humans to read and write. It is easy for machines to parse JSON and generate.
  • JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.
  • These properties make JSON an ideal data-interchange language.
  • It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999.

Why do we use JSON?

  • Exchanging Data When exchanging data between a browser and a server, the data can only be text.
  • JSON is text, and we can convert any JavaScript object into JSON, and send JSON to the server.
  • We can also convert any JSON received from the server into JavaScript objects.
  • This way we can work with the data as JavaScript objects, with no complicated parsing and translations.

Is there any JSON data will be sent via the server?

NO. When uploading file and pasting text in the JSON editor, no data is sent via the server.
