What about mixed content?

Text content is stored under a #text key (configurable) alongside child elements. Enable "Always create text node" if you want every element to use the same shape.

Why is one child an object but two children an array?

The parser cannot know from a single occurrence that a tag repeats. Add the tag name (or a dotted path like library.book) to "Always arrays" to get a consistent array.

Are namespaces preserved?

Namespace prefixes are kept in key names by default (ns:title). Enable "Remove namespace prefixes" to drop them; the prefix is never resolved to its URI.

Can I convert JSON back to XML?

Yes. Switch to JSON → XML. The JSON needs exactly one top-level key to serve as the root element; otherwise it is wrapped in the root element you specify. Arrays repeat the element.

XML to JSON

Translate XML into JSON, preserving attributes, text content and element hierarchy, and convert JSON back into well-formed XML. Control the attribute prefix and text-node name, force specific tags to always be arrays, strip namespace prefixes, keep comments and CDATA, and coerce numbers and booleans. Malformed XML is reported with the line and column.

Repeated sibling elements become arrays; a single child becomes an object unless listed under "Always arrays". Mixed content keeps text under the text-node key.

JSON to YAML

Convert JSON into clean YAML with control over quoting, wrapping, anchors and multi-document output.

YAML to JSON

Convert YAML into strict JSON, with multi-document streams, YAML-only types and duplicate keys handled.

TOML to JSON

Convert TOML config to JSON and JSON back to TOML, with Cargo, pyproject and netlify presets.

How to use XML to JSON

1Choose the direction: XML → JSON or JSON → XML. Swap reverses it using the current output as input.
2Paste or upload the document; errors point at the line and column.
3Set the attribute prefix and text-node name, and list any tags that must always become arrays.
4For JSON → XML, set the root element name and whether to add the XML declaration, then copy or download.

About XML to JSON

XML to JSON is part of FizzKit — a collection of focused developer and ad-tech tools. Because everything runs locally, it works offline once loaded and never exposes your data to a remote server.

Frequently asked questions

Attributes become keys prefixed with @_ (configurable) on the element object, for example { "book": { "@_id": "1", "title": "…" } }. Going the other way, keys with that prefix become attributes.
