Format & Validate JSON Instantly: The Developer’s Secret Weapon
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange information. You’ll see it everywhere, in REST API’s, databases, web servers, mobile apps, and more.

example
{
“name”: “Jaylene”,
“site”: “jaylenenavarrete.org”,
“role”: “Web Developer”
}
Easy to read, but just as easy to mess up, especially when working with large, nested structures.
