Format, compress and validate JSON

Format minified JSON, compress multiline data, and find syntax errors. Parsing preserves the original spelling of numbers and duplicate keys, while sorting only changes the order of the object keys.

Indented by 2 or 4 spaces or tab;
recursive sorting of keys and optional Unicode ASCII escaping;
checking strict JSON with line number and column;
opening a JSON file, copying and downloading the result.

Standard JSON does not allow comments or trailing commas. Sorting does not change arrays; Unicode escaping preserves the original values.
