XML format guide and tools

XML uses elements and attributes; JSON uses objects and arrays. Their structures are not identical.

Before you convert

Check repeated elements, attributes and root names after conversion. External entities and unsafe constructs are not supported. Do not assume a lossless round trip for every XML document.

Check each tool’s processing label: browser and server tools handle files differently.
