Why Convert XML and JSON Online?

XML is still common in older services. JSON is common in REST APIs. This page converts pasted XML to pretty-printed JSON, or pasted JSON to formatted XML, in the browser with fast-xml-parser. It is not a file-upload converter and does not validate SOAP, XSD, or a live API.

Choose XML โ†’ JSON or JSON โ†’ XML, paste text, then click Convert. Data is not sent to Toolo's servers. Round-trips are not lossless: comments are typically dropped, numbers and booleans may be parsed from tag text, and attributes use an @_ prefix in JSON.

Key Features & Benefits

Built for local text conversion between XML and JSON:

  • Client-Side Privacy

    Conversion runs in the browser. Payloads are not uploaded or saved on a remote server. Pasting secrets still has local risks (extensions, shoulder surfing).

  • Two-Way Conversion

    Switch XML โ†’ JSON or JSON โ†’ XML, then click Convert. Switching direction tries to convert the current input into the other box. There is no file picker and no live conversion as you type.

  • Attributes and Nesting

    Attributes are kept as JSON keys with an @_ prefix (for example @_id), not as unprefixed property names. Mixed element text uses #text. Repeated sibling tags usually become JSON arrays. JSON โ†’ XML only emits attributes if those @_ keys are present.

  • Free, No Account

    Use it without a login or paid plan. There is no coded size cap. Very large pastes can still slow the browser. Namespaces are not stripped; they are not schema-validated either.

Frequently Asked Questions (FAQ)

Is my XML or JSON payload stored or logged during conversion?

No. Conversion runs in your browser with JavaScript (fast-xml-parser). Text is not uploaded, transmitted, or stored on a Toolo server.

How does the converter handle XML attributes?

Attributes are mapped to JSON keys prefixed with @_. Nested tags become nested objects. This is not a lossless copy of every XML feature (comments, doctypes, and some type coercions differ).

Do I need to install external libraries or CLI tools?

No. The page runs in a modern browser (Chrome, Safari, Firefox, or Edge). You paste text; you do not install a CLI. Large documents still need enough memory on the device.
