Use this JSON operation to transform or present valid JSON while preserving the intended values and structural relationships.

JSON

JSON text to format.

Indent

Spaces per indentation level.

Format JSON text with consistent indentation and a trailing newline. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Pretty

Formatted JSON.

• JSON does not represent comments, references, dates, binary values, non-finite numbers, duplicate-key meaning, or arbitrary object prototypes. Flattening requires an escaping convention, and pretty printing or minification does not validate application schemas.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Parse and schema-validate untrusted data, document path escaping and collision rules, and round-trip transformed structures with representative edge cases.

• JSON Minifier

  Remove all insignificant whitespace from valid JSON text while preserving values.

• JSON Patch Applier

  Apply a minimal RFC 6902-style add/remove/replace patch with RFC 6901 pointers to a JSON document.

• JSON Diff

  Produce a minimal deterministic RFC 6902-style add/remove/replace patch turning one JSON document into another.
