XML

Extensible Markup Language

XML encodes data as nested tags with attributes. It predates JSON as the standard interchange format and still underpins enterprise systems, SOAP APIs, RSS, SVG, Office file internals and most government data feeds — which is why converting between XML and JSON is a permanent chore rather than a migration.

Extension: .xml
MIME type: application/xml

01 Convert XML to something else

XML to JSON Attributes preserved, well-formedness checked, position-accurate errors.
XML to CSV Finds the repeating element and makes it the rows.
XML to YAML Markup in, readable config out.

02 Convert something else to XML

JSON to XML Legal element names guaranteed, entities escaped, one real root.
CSV to XML Each row an element, column names as tags, names made legal.
YAML to XML Config in, markup out. Keys sanitised to legal element names.

Opening a .xml file

If you landed here because something handed you a .xml file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
