Overview

The JSON to EDN Converter is a streamlined utility designed to transform standard JSON data structures into EDN (Extensible Data Notation) format, facilitating seamless integration with Clojure and ClojureScript environments.

When to Use

  • •When migrating configuration files from JSON to EDN for Clojure applications.
  • •When you need to represent complex data structures in a format that supports Clojure-specific types like keywords and symbols.
  • •When preparing data payloads for interoperability between web services and Clojure-based backends.

How It Works

  • •Paste your raw JSON data into the input field.
  • •Adjust the indent size setting to define your preferred output formatting.
  • •Click the convert button to generate the equivalent EDN representation instantly.

Use Cases

Standardizing configuration files for Clojure projects.
Converting API responses into a format compatible with Clojure data processing libraries.
Refactoring legacy JSON-based data stores into more expressive EDN structures.

Examples

1. Converting App Configuration

Clojure Developer
Background
A developer is moving a web application's configuration from a JSON file to an EDN file to leverage Clojure's native data handling.
Problem
Manually rewriting nested JSON objects into EDN syntax is error-prone and slow.
How to Use
Paste the JSON configuration into the input area and set the indent size to 2 for readability.
Example Config
indentSize: 2
Outcome
The JSON object is converted into a clean, readable EDN map, ready to be used in the project's config.edn file.

FAQ

What is EDN?

EDN (Extensible Data Notation) is a data format used by Clojure to represent data structures, similar to JSON but with support for more types like keywords, symbols, and sets.

Can I convert large JSON files?

Yes, the tool handles large JSON objects efficiently, provided they are valid JSON syntax.

Does this tool support custom Clojure types?

The tool converts standard JSON types to their EDN equivalents. Custom Clojure types may require manual adjustment after conversion.

Is my data stored on your server?

No, all conversion processes occur locally in your browser to ensure your data remains private.

What happens if my JSON is invalid?

The tool will return an error message indicating the syntax issue, allowing you to correct your JSON before attempting the conversion again.
