Quick answer: JSON is a structured text format widely used by APIs and applications.
What is JSON Formatter?
JSON is a structured text format widely used by APIs and applications. A formatter adds indentation to help developers inspect objects, arrays and values. Paste sample JSON into the formatter, run the operation and inspect the output. Valid JSON requires double-quoted property names and correctly placed commas. A formatter cannot fix every malformed document automatically.

Detailed examples and best practices
JSON uses double-quoted property names, colons between keys and values, and commas between entries. Arrays use square brackets; objects use curly braces.
For example, a valid object is {"name":"Alex","active":true}. Trailing commas and comments are not permitted in standard JSON.
A formatter improves readability but does not guarantee that your data matches an API schema. Check required fields and expected types separately.
