# XML to JSON converter: run it free, or from your agent Converts XML to JSON and JSON to XML, with attribute prefix, text key, typed values and always-array options. ## Prompt Use looot to turn an XML feed into rows. 1. Set up https://looot.ai/skill.md. 2. Search the catalog for an endpoint that fetches a URL's raw content and check its price before you call. 3. Fetch [RSS or sitemap URL]. 4. Convert the XML to JSON with attributes prefixed by @. 5. Return a CSV with one row per item: title, link and date. ## What it needs An XML document or a JSON value ## What comes back - JSON with attributes and text - XML with attributes and repeated elements - line and column of a parse error ## Endpoints and providers None. The tool on the web page runs in the browser and calls no endpoint. ## What it costs Nothing. The tool on the web page runs in the visitor's browser: no account, no API call and no limit per hour. The prompt above runs the same job from your own looot account with current data, billed per call. ## Read RSS and sitemaps Turn a feed or a sitemap into JSON you can loop over. ## Modernise SOAP Convert a SOAP or legacy XML response into JSON for a newer service. ## Feed an agent Give an agent JSON instead of XML, which it reads with fewer mistakes. ## Build test fixtures Write a fixture in JSON and convert it to the XML an old API expects. ## How are XML attributes converted? Each attribute becomes a key with a prefix, @ by default, so gives { "@id": "7" }. Change the prefix, or drop attributes when you do not need them. ## What happens to repeated elements? Two or more children with the same name become an array. A child that appears once stays a single value, unless you turn on Always arrays, which makes every element a list so the shape does not change with the data. ## Where does element text go when it also has attributes? Under the text key, #text by default. An element with only text becomes a plain string. ## Are numbers and booleans converted? Only when you turn on Numbers and booleans. By default every value stays a string, because XML has no types and a zip code such as 02134 must keep its leading zero. ## Can it convert JSON to XML? Yes. Switch the direction. Keys with the attribute prefix become attributes, the text key becomes element text and arrays become repeated elements. A value with several top level keys is wrapped in a root element. ## Are namespaces and comments kept? Namespace prefixes stay part of the name, such as soap:Body, and xmlns declarations become attributes. Comments and processing instructions are dropped. ## Is it safe to paste untrusted XML? Yes. The parser never loads external entities or DTDs, so the XXE attacks that hit server-side parsers do not apply. A DOCTYPE with an internal subset is rejected. ## Is my XML uploaded? No. Parsing and conversion run in your browser. ## Related tools - /free-tools/json-formatter - /free-tools/json-to-csv - /free-tools/sitemap-xml-generator ## Last reviewed 2026-10-14.
