What is JSON to Amazon Ion Converter?
This tool converts JSON data into Amazon Ion text format. Amazon Ion is a richly-typed, self-describing data format developed by Amazon that extends JSON with typed nulls, timestamps, binary data, annotations, and S-expressions. Ion is the native data format for AWS QLDB and is used across Amazon's internal services.
How to Use
- Paste your JSON data into the input area
- Toggle pretty print for formatted output or compact mode
- Enable type annotations to add Ion type annotations (string::, int::, decimal::, bool::, list::, struct::)
- Click "Convert" and copy the Ion text output
Why Use This Tool?
Tips & Best Practices
- All valid JSON is also valid Ion — Ion text is a superset of JSON
- Ion distinguishes between integers (1) and decimals (1.0), unlike JSON where all numbers are the same type
- Use type annotations when you need explicit type information for downstream Ion processors
- For AWS QLDB PartiQL queries, Ion text format is the standard document representation
Frequently Asked Questions
What is Amazon Ion?
Amazon Ion is a richly-typed, self-describing data format developed by Amazon. It is a superset of JSON that adds typed nulls (null.string, null.int), timestamps, binary large objects (blobs/clobs), annotations (type::value), and S-expressions. Ion is used by AWS services like QLDB and DynamoDB for efficient data serialization.
How does Ion differ from JSON?
Ion extends JSON with typed nulls (null.string, null.int), timestamps, binary large objects (blobs/clobs), annotations (type::value), and S-expressions. Ion text format is a superset of JSON, meaning all valid JSON is also valid Ion.
What Ion types are generated from JSON?
JSON strings become Ion strings, numbers become Ion decimals or ints (Ion distinguishes between integer and floating-point), booleans become Ion booleans, null becomes Ion null, arrays become Ion lists, and objects become Ion structs.
Can I use this with AWS QLDB?
Yes! The generated Ion text format is compatible with Amazon QLDB. QLDB uses Ion as its native data format for PartiQL queries and document storage.
Is my data sent to a server?
No, all processing happens entirely in your browser. Your JSON data never leaves your device.
