Converting XML data to JSONL is a shape change — the same records expressed the way the next tool in your pipeline expects to read them. JSONL (JSON Lines) earns its place here: append-friendly, streamable records for large datasets and ML pipelines. XML is the verbose, strongly structured markup behind sitemaps, RSS, invoices and countless enterprise systems. It is precise, self-describing and heavy to work with by hand.
XML is the verbose, strongly structured markup behind sitemaps, RSS, invoices and countless enterprise systems. It is precise, self-describing and heavy to work with by hand.
Records and field names carry over from XML to JSONL 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 JSONL has a way to express them, otherwise values become plain strings.
What you gain with JSONL: Append-friendly, streamable records for large datasets and ML pipelines.
Drop your XML file above and Morphio decodes it locally, then re-encodes it as JSONL 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 XML to JSONL 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 XML 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 XML to JSONL 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 XML into JSONL structurally, so nothing is re-compressed. Only features JSONL 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.
