Amazon Ion vs JSON: Format Comparison
Key differences between the two formats
| Feature | Amazon Ion | JSON |
|---|---|---|
| Data types | Extended types: decimal, timestamp, symbol, blob, clob | Basic types: string, number, boolean, null, array, object |
| Precision | Arbitrary precision decimal and exact timestamps | IEEE 754 floating point, limited precision |
| Annotations | Type annotations like price::123.45 | No type annotations |
| Binary format | Compact binary encoding available | Text-only format |
| Comments | Full comment support | No comment support |
| Symbol tables | Shared symbol tables for efficiency | Raw string keys only |
| Use case | AWS services, high-precision data, schema evolution | Web APIs, general data interchange |
When to Convert
Common scenarios where this conversion is useful
AWS data migration and integration
Convert Ion data from AWS services like DynamoDB, Amazon QLDB, or other AWS data stores to JSON for processing with standard tools and APIs.
Data processing and analytics workflows

Frequently Asked Questions
Ion decimals become JSON numbers (with potential precision loss), timestamps become ISO 8601 strings, symbols become strings, and blobs become base64-encoded strings. Type information is preserved as metadata where possible.
Ion annotations like price::123.45 are preserved as metadata in the JSON output. The annotated value is converted to the appropriate JSON type, with annotation information available for reference.
No. The entire conversion happens in your browser using JavaScript. Your data never leaves your device, making it safe for sensitive AWS data and enterprise information.
Yes. The converter supports both Ion text format (.ion) and binary Ion format. Binary Ion is automatically detected and parsed correctly to equivalent JSON structure.
Ion timestamps are converted to ISO 8601 date strings in JSON. Precision is preserved where possible, and timezone information is maintained in the string representation.
Yes. Since the conversion runs in your browser, file size is limited only by your device's memory. Large Ion files with complex nested structures work well on modern devices.
Yes. Ion symbol tables are resolved during parsing, with symbols converted to their string representations in the JSON output. Shared symbols are expanded to full string values.
Ion arbitrary precision decimals are converted to JSON numbers. Where precision loss might occur, the converter attempts to preserve accuracy or provides string representations for critical values.
The converter preserves data accuracy where possible, but Ion's arbitrary precision decimals may lose precision when converted to JSON numbers. Review output carefully for financial calculations requiring exact precision.
Yes, completely free with no limits on file size or number of conversions. No account required, perfect for AWS data processing and enterprise workflows.
