What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard and is widely used for data exchange between web servers and clients.
JSON supports two primary data structures:
- Objects — An unordered collection of key/value pairs enclosed in curly braces
{ } - Arrays — An ordered list of values enclosed in square brackets
[ ]
How to Use
- Paste your JSON — Copy and paste any JSON data into the top textarea. You can also type directly or paste from clipboard.
- Choose an action — Click Format JSON to beautify with proper indentation, Minify to compress into a single line, or Validate to check for syntax errors.
- Choose indentation — Select 2 spaces, 4 spaces, or Tab from the dropdown before formatting.
- Copy or download — Use the copy button on the output area or click Download .json to save the result as a file.
