Core model
XML to JSON migration is common when legacy enterprise feeds move into modern APIs, warehouses, or event systems. XML carries elements, attributes, text nodes, namespaces, and repeated structures. JSON carries objects, arrays, primitives, and nulls. A converter must decide how attributes map, where rows begin, and whether repeated elements become arrays or flattened columns for table-like outputs. FileTypeConverters can infer row candidates for simple XML and exposes row-path choices for deterministic parsing. Attributes receive an attribute prefix so they do not collide with child elements. Nested elements can remain nested for JSON output or flatten further when the next step is CSV or spreadsheet export. The important part is consistency: pick a row path and separator, document them, and keep them in your migration runbook. Validate with edge cases, not only a happy sample. Include records with missing optional elements, repeated child nodes, attributes, escaped text, and unusual encodings. Compare counts from the XML source with counts in the JSON output. If namespaces are business-significant, verify how the upstream feed represents them and whether your receiving API expects namespace prefixes or simplified names.

FAQ
Can I automate this?
Yes. Use the API for repeatable production conversions and MCP for assistant-driven exploratory work.
Will formatting be preserved?
Only when the target format can represent it. Pair pages list specific preserved and dropped details.
