Frequently Asked Questions
What is the difference between formatting and minifying?
Formatting adds indentation and newlines for human readability. Minifying removes all whitespace to reduce payload size — useful for production APIs. Both represent identical data.
Is my API response data safe?
Yes. All processing happens locally in your browser. Your API keys, tokens, and response data are never sent to any server.
Can this handle large responses?
Yes, for typical API responses. For very large responses (>10MB), browser performance may degrade. For such cases, consider using a dedicated desktop tool like jq or xmllint.
