Free Online JSON to SVG Diagram
Paste any JSON object or array and the tool parses it and lays it out as a left-to-right structure tree, drawn as a colourful SVG entirely in your browser. Each key becomes a node, nested objects and arrays branch out, and leaf values are shown inline. Download the result as an SVG you can drop into documentation or slides, or copy the raw markup. Large arrays are capped at 40 branches and eight levels deep to keep the diagram readable.

Questions about JSON to SVG Diagram
What JSON shapes are supported?
Any valid JSON: objects, arrays, strings, numbers, booleans and null. Objects and arrays become branching nodes; primitive values are shown as leaves. Invalid JSON reports a clear error instead of drawing.
Is the SVG editable?
Yes. It is plain SVG markup, so you can open it in any vector editor or paste it into HTML. The download is a self-contained .svg file with no external dependencies.
About JSON to SVG Diagram
Turn JSON into an SVG tree diagram with our free online JSON to SVG Diagram. 100% browser-based, fast, and private—no login or file uploads required.
These text and code tools clean and transform strings: count words, convert case, deduplicate lines, encode or decode Base64 and URLs, escape entities, hash, format JSON and compare two versions.
This tool runs in your browser. The file is not uploaded. Everything runs on the text you paste, so you can safely process snippets of code or logs; nothing is sent anywhere, and clearing the box removes it from memory.
