Converting YAML data to XML is a shape change — the same records expressed the way the next tool in your pipeline expects to read them. XML (Extensible Markup Language) earns its place here: strict, self-describing structure with schema validation and long institutional support. YAML expresses structured data with indentation rather than brackets, which is why CI pipelines, Kubernetes and app configuration live in it.

Records and field names carry over from YAML to XML one-for-one. The real difference is shape: nested structures flatten when the target is tabular, and flat rows gain a wrapper when the target is hierarchical. Types are preserved where XML has a way to express them, otherwise values become plain strings.

Drop your YAML file above and Morphio decodes it locally, then re-encodes it as XML using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
Open the YAML to XML page, drop your document on the drop zone and press convert. Morphio runs local parsers such as pdf.js that execute in your own tab, so the YAML data never leaves your device and no server ever receives a copy.
Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting YAML to XML only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
No. The content is remapped from YAML into XML structurally, so nothing is re-compressed. Only features XML has no way to express are left behind.
Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.
No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
