XML to JSON

Convert XML to JSON with ordered nodes or grouped objects. Preserve attributes, namespaces and mixed content; inspect errors and export locally.

Choose your path

Built around the job you need to finish

Map namespace-aware XML 1.0 into an explicit ordered or grouped JSON representation without silent loss of attributes or mixed prose.

Integration developer

Keep qualified names, namespaces and attributes.

Convert namespaced XML, inspect attributes and repeated children, compare grouped policy.

Required identity and values remain represented; unsupported loss is refused or explained.

Documentation author

Preserve prose position, CDATA and comments.

Convert mixed content using ordered nodes, attempt grouped mapping, recover without partial output.

Sequential content remains inspectable and grouped mixed content is refused.

Mobile configuration reviewer

Correct source errors and export a current result.

Change whitespace settings, test invalid prefix, rerun and copy/download on narrow viewport.

Labeled controls stack without page overflow and changed input cannot export stale output.

Authoritative checks for this tool

Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Reference & details

How it works

Namespace-aware parsing

Saxes validates XML 1.0 well-formedness and namespace bindings before producing output. DTDs, external entity declarations, XML 1.1 and unsupported limits are refused.

Two explicit representations

Ordered nodes carry names, namespace URIs, attributes and sequential children. Grouped objects use @attributes and #text, collect repeated names and refuse mixed text/elements; cross-name order and metadata are not retained.

Bounded local conversion

A disposable browser worker has a ten-second timeout. Input/output limits are one/two million characters; XML also permits 40 element levels, 10,000 elements and 20,000 parsed nodes. Changes invalidate old output.

Example Scenarios

An API integrator checks that p:item and its URI, id attributes and repeated elements remain represented before mapping into an application schema.

A writer converts Hello <b>team</b>! as ordered children, keeping prose position, CDATA and comments visible instead of treating markup as plain text.

A maintainer chooses grouped objects for element-only data, explicitly ignores layout whitespace, then corrects an undeclared prefix without copying a partial result.

FAQ

Use ordered nodes for mixed content, sibling sequence or namespace metadata. Use grouped objects only when its documented omissions match your consumer. There is no universal XML-to-JSON mapping.

Text and attributes stay strings. Empty leaves become empty strings in grouped mode. Layout removal is opt-in; blank leaves, mixed prose and inherited xml:space preservation remain intact.

No. Parsing resolves entities and normalizes XML line endings; JSON mapping also changes syntax. This tool does not preserve signatures, perform canonicalization or validate an XML schema.

Malformed tags, namespace errors, illegal characters and unsupported declarations produce an error and no partial output. Correct the source or supported mapping and run again.

Conversion uses browser memory without automatic source storage or upload. Engine assets may need a connection. Copy contains only JSON; UTF-8 file import rejects invalid bytes and conflicting declarations. Download feedback confirms a request, not an OS-saved file.

About XML to JSON

Choose the representation your consumer needs before converting. Ordered nodes preserve structure that grouped JSON objects cannot express; neither mapping is a byte-preserving XML round trip.
