Frequently Asked Questions
What is the difference between JSON and XML?
JSON and XML both represent structured data, but JSON uses braces, brackets, and key-value pairs for a compact, easy-to-parse format common in modern APIs, while XML uses opening and closing tags plus optional attributes, and is still the standard for SOAP services, RSS/Atom feeds, and many legacy enterprise systems and config formats.
Is my JSON or XML data uploaded anywhere?
No. All parsing and conversion happens locally in your browser using JavaScript. Your data is never sent to any server, so private API payloads and config files stay private.
How are arrays represented when converting between JSON and XML?
Converting JSON to XML, an array becomes a wrapper element containing one repeated child element per item, named using the array item element name option (default item). Converting XML to JSON, repeated sibling elements with the same tag name at the same level become a JSON array automatically.
How are XML attributes handled?
JSON to XML output has no attributes; every JSON key becomes a child element. Converting XML to JSON, turning on Include attributes represents each attribute as an @attributeName key on the resulting object (and #text for any element text alongside attributes); leaving it off drops attributes and keeps only element content.
Why does my conversion fail with an error?
JSON requires double-quoted keys, no trailing commas, and balanced braces and brackets; the error message reports what the parser found and roughly where. XML requires every tag to be closed and properly nested; the error message includes the line and column where the parser stopped, which pinpoints the issue.
Is this converter free to use?
Yes, this JSON to XML converter is 100% free with no limits, no sign-up, and no ads.
