HJSON vs JSON: Format Comparison
Key differences between the two formats

| Comments | Supported with // and /* */ syntax | Not supported |
| Unquoted keys | Allowed for simple keys | All keys must be quoted |
| Trailing commas | Allowed and ignored | Syntax error |
| Multiline strings | Supported with triple quotes | Requires escape sequences |
| Quoteless strings | Simple strings don't need quotes | All strings must be quoted |
| API compatibility | Requires conversion for most APIs | Universal API support |
| Human readability | Very high, designed for humans | Good for machines, harder for humans |

Frequently Asked Questions
Yes for data values. All HJSON data types (strings, numbers, booleans, arrays, objects) convert perfectly to JSON. However, comments and formatting are removed since standard JSON doesn't support them.
All standard HJSON features: comments (// and /* */), unquoted keys, quoteless strings, trailing commas, multiline strings with triple quotes, and relaxed syntax rules.
No. The entire conversion happens in your browser using JavaScript. Your HJSON configuration data never leaves your device, making it safe for sensitive config files.
Yes. Deeply nested objects and arrays are converted to properly formatted JSON with correct nesting. There is no depth limit for the conversion.
Comments are stripped during conversion since standard JSON doesn't support comments. If you need to preserve comments, consider converting to JSONC or documenting them separately.
HJSON multiline strings (using triple quotes) are converted to standard JSON strings with proper escape sequences (\n for newlines).
Yes. Unquoted keys and quoteless strings in HJSON are automatically quoted in the JSON output to comply with JSON specification.
Yes. Since the conversion runs in your browser, file size is limited only by your device's available memory. Large configuration files work well on modern devices.
Yes. The converted JSON follows the strict JSON specification and is compatible with all APIs, databases, and tools that expect standard JSON format.
Yes, completely free with no limits on file size or number of conversions. No account required.
