Convert JSON-LD to Markdown.
Drop a JSON-LD file and read its linked data as clean Markdown in seconds. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Written for machines,
read by no one.
JSON-LD is linked data dressed as JSON, full of @context, @id and @type keys that power schema.org but read like noise. Converting turns each node into a plain Markdown section.
{
"@context": "https://schema.org",
"@id": "https://example.org/alice",
"@type": "Person",
"name": "Alice Lee",
"jobTitle": "Engineer"
}
## alice
- **type:** Person
- **name:** Alice Lee
- **jobTitle:** Engineer
Everything you
actually need.
Linked-data nodes in, readable Markdown out, with no server and no account anywhere.
It never leaves your browser
The .jsonld is read and parsed on your device. Nothing is uploaded to any server, ever.
# Heading
- point one
3 chunks
AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
## alice
- type: Person
- name: Alice Lee
Nodes become sections
Each node becomes a heading from its @id, with @type and properties listed as bullets beneath it.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for JSON-LD, so the page never drifts from what the converter really does.
Kept
4- Nodes as headings from @id
- @type as a bullet
- Properties as bullets
- Shortened terms
Dropped
3- @context expansion
- Deeply nested objects (shown as raw JSON)
- Full IRIs
- name: Alice Lee
- jobTitle: Engineer
