About JSON to XML Attributes
JSON to XML Attributes converts a flat JSON object into the attribute string you would drop inside an XML or HTML start tag.
Paste an object such as {"id":"1","width":120,"open":true} and the tool produces id="1" width="120" open="true", ready to paste between the angle brackets of an element.
It is a quick way to move structured data from a JSON source into markup without hand-writing each attribute and worrying about quoting.
The conversion is careful about correctness.
Every value is XML-escaped, so ampersands, angle brackets and quotes turn into their entity forms and cannot break the surrounding markup.
Numbers and booleans are rendered as their text form, and a null value becomes an empty attribute.
Because an XML attribute can only hold a scalar, nested objects and arrays are rejected with a clear message rather than being silently flattened, and each key is validated as a legal XML attribute name so the output is always well formed.
Everything happens locally in your browser — nothing you paste is uploaded or stored — so it is safe for private data and keeps working offline.
It is handy when generating SVG, configuring XML templates, or hand-assembling HTML elements from a small JSON config.
FAQ
Can the JSON contain nested objects or arrays?
No. An XML attribute can only hold a scalar value, so nested objects and arrays are rejected with a clear message. Keep the object flat.
Are special characters escaped?
Yes. Ampersands, angle brackets and quotes are converted to XML entities so the output stays well formed.
