XML to JSON Without Losing Structural Clues

Map attributes, repeated children, namespaces, and text explicitly.

<order id="A1"><item qty="2">Cable</item></order>

{"order":{"@id":"A1","item":{"@qty":"2","#text":"Cable"}}}

Reproducible method

1. Preserve the original and create the smallest representative sample.
2. Run a strict parse or validation before transformation.
3. Record options, compare counts and structure, then test in the receiving system.

Common error

Singleton and repeated elements can produce inconsistent shapes.

Reduce a failure while retaining the problematic structure; this separates malformed input from unsupported behavior.

Technical limitation

Comments, ordering, namespaces, and mixed content may not round-trip.

A successful preview does not remove format ambiguity or downstream requirements.

Security and privacy

Disable external entities in server parsers and redact attributes.

Local processing reduces transfer risk but cannot protect a compromised browser, unsafe extensions, clipboard history, or later misuse.

Verification checklist

• Check field, record, page, or byte counts.
• Review edge cases and error output.
• Retain the original until acceptance.
• Document assumptions for automation.
