How do I convert JSON to EDN?

Upload or paste your JSON data into the converter, select JSON as source and EDN as target, then click Convert. The tool will parse the JSON into a tree and serialize it using EDN syntax, handling maps, vectors, strings, numbers, booleans, and null values. You can then download the resulting .edn file or copy it to clipboard.

How does the conversion handle data structures and types?

The conversion preserves the full structure of your data. JSON objects become EDN maps, arrays become vectors, strings remain strings, numbers are retained as numbers (with integer/float distinction), booleans map to true/false, and null maps to nil. Nested structures are handled recursively, and duplicate keys are merged according to EDN map semantics. The output is text-based and can be pretty-printed for readability.

Is JSON-TO-EDN free to use?

Yes, JSON-TO-EDN on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! JSON-TO-EDN works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.
