How is this result calculated?
JSON is a structured text format with objects, arrays, strings, numbers, booleans and null. The formatter validates the syntax and re-indents the document.
Valid JSON uses double quotes for keys and strings. Trailing commas are not allowed by the JSON standard.
Frequently asked questions
