XML to JSON Converter
Instantly transform structured XML schemas into readable JSON objects, or serialize JSON trees back to clean XML markup. Validates syntax locally, formatting files with customizable indentation.
Understanding XML and JSON Mapping
XML and JSON are the two most popular data serialization structures for APIs and configuration tables. While XML relies on custom opening/closing element hierarchies and node attributes, JSON models standard nested JavaScript dictionaries and lists.
Converting between them requires structured mapping of XML element lists to JSON arrays and parsing tag properties as dictionary fields. Our tool accomplishes this recursively inside sandboxed browser clients instantly.
How the XML ⇄ JSON Rules Map
- XML Elements: Map directly to JSON key properties containing the child tree.
- Element Attributes: Grouped under an
@attributeskey containing key/value entries of the attributes. - Adjacent Duplicate Tags: Compacted automatically into ordered JSON list arrays.
- Plain Text Tags: Parsed simply as raw string attributes of the parent node.
Frequently Asked Questions
How do I convert XML to JSON?
Select the "XML ➡️ JSON" tab, paste your XML data into the left input panel, and the structured JSON equivalent will generate in the right panel. You can customize the indent format (2 spaces, 4 spaces, or tabs).
How do I convert JSON to XML?
Select the "JSON ➡️ XML" tab, paste your formatted JSON string into the left input panel. The tool will parse it and generate valid XML tags. If the JSON structure contains custom properties like "@attributes" or "#text", these are correctly serialized as XML node attributes and text contents.
Is my data secure?
Yes! All conversions are handled client-side using native browser DOMParser and custom recursive tree serialization. No data is ever transmitted to any backend servers or stored in any logs.
How are attributes and child elements parsed?
Our converter recursively maps XML elements. Node attributes are grouped under an "@attributes" key. Nested text structures map to a "#text" property, and duplicate adjacent tags are beautifully compacted into standard JSON arrays.
Technical Specifications
- Runs 100% client side utilizing the browser native
DOMParser()and XMLSerializer modules. - Accurately parses node trees to build clean recursive JavaScript dictionaries, keeping page overhead extremely low.
- Features instant live validation which isolates exact syntactic mismatches on input fields.
