How do I format JSON with YAML Formatter?

Paste your JSON into the input box, click Format (or Beautify), and YAML Formatter instantly returns properly-indented, human-readable JSON with syntax highlighting. Everything happens in your browser — no upload required.

Is my JSON data private when I use YAML Formatter?

Yes. YAML Formatter runs 100% client-side in your browser. Your JSON is never sent to a server, never logged, and never leaves your device — safe to use with production API responses, secrets, and PII.

Can I convert JSON to CSV, YAML, TypeScript, or XML here?

PromptSpace hosts a full JSON toolkit — JSON to CSV, JSON to YAML, JSON to TypeScript interfaces, JSON to XML, and their reverse converters. If YAML Formatter is one of them, use it directly; otherwise browse the JSON category for the matching converter.

Does YAML Formatter validate JSON against a schema?

YAML Formatter performs full JSON syntax validation and reports errors with line/column position. JSON Schema (draft-07) validation is available in the dedicated JSON Validator tool — this one focuses on syntax correctness and structural integrity.

What's the difference between JSON minify and beautify?

Beautify (format) adds indentation and line breaks so JSON is easy to read. Minify strips all whitespace to produce the smallest possible payload — ideal for API transport, storage in a database column, or embedding in a config value. Both operations preserve the exact same data.

Does YAML Formatter handle large JSON files?

Yes — YAML Formatter handles multi-megabyte JSON documents smoothly because parsing runs on your device using the browser's native JSON engine. There is no file size cap and no signup required.
