Response to JSON
Convert XML, YAML, query strings and key-value data to JSON
About Response to JSON
Response to JSON is a free online converter that transforms common data formats — XML, YAML, URL query strings, and key-value / properties files — into clean, formatted JSON. Paste your input, let the tool auto-detect the format or choose it manually, and get valid JSON output you can copy in one click.
It is especially useful for developers working with APIs or config files: convert an XML API response to JSON for easier processing, turn a YAML config into JSON for a tool that requires it, parse a URL query string into a JSON object, or convert a .properties or .env-style key=value file into structured JSON.

Frequently Asked Questions
XML, YAML (basic), URL query strings (e.g. name=Alice&age=30), and key-value / properties files (e.g. name=Alice or name: Alice, one pair per line).
The tool inspects the first character and structure of your input. Input starting with < is treated as XML. Input with key: value indentation patterns is treated as YAML. Input with & and = signs is treated as a query string. Everything else falls back to key-value parsing.
Yes. XML is parsed using the browser's native DOMParser, so nested elements, attributes, and repeated sibling tags (converted to arrays) are all handled. YAML nested objects and arrays (using indentation and - prefixes) are also supported.
Yes. XML attributes are included under an "@attributes" key on the element object, following a widely used XML-to-JSON convention.
No. All conversion logic runs entirely in your browser using JavaScript. Your data never leaves your device.
