Converting YML data to JSON is a shape change — the same records expressed the way the next tool in your pipeline expects to read them. JSON (JavaScript Object Notation) earns its place here: nested, typed, machine-readable structure that every language parses natively. YML is YAML with the shorter extension — the same indentation-based structured data format used across DevOps tooling.

Records and field names carry over from YML to JSON 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 JSON has a way to express them, otherwise values become plain strings.

Drop your YML file above and Morphio decodes it locally, then re-encodes it as JSON using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Free supports batches of 5 files; Pro supports batches of 250, subject to your device's memory. See exactly how in-browser conversion works.
Open the YML to JSON 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 YML 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 YML to JSON 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 YML into JSON structurally, so nothing is re-compressed. Only features JSON has no way to express are left behind.
Yes — Free supports batches of 5 files and 10 conversions per day; Pro supports batches of 250 with no daily conversion cap. Your device's memory can impose a lower practical limit. Only usage counts reach the server, never files.
No. The conversion runs entirely inside your browser, so the file never leaves your device. The page and the required decoder must load first; free usage-limit checks may require a connection.
