About This Tool
JSON doesn't natively support comments, but this tool provides a workaround by adding a "_comments" object to your JSON structure. Each key in your JSON can have a corresponding explanation in the comments section.
This is particularly useful for configuration files, API documentation, and data files where you need to document the purpose of each field for future reference or team collaboration.
All processing happens in your browser - no data is sent to servers.
Frequently Asked Questions (FAQ)
Why can't I add comments directly to JSON?
JSON (JavaScript Object Notation) specification doesn't support comments. Unlike JavaScript, pure JSON cannot contain // or /* */ style comments. This is by design to keep JSON simple and language-agnostic.
How does this tool work around JSON's lack of comment support?
This tool adds a special "_comments" object to your JSON structure. Each key in your original JSON can have a corresponding explanation in the _comments section. While not standard comments, this provides a way to document your JSON structure.
Will the _comments section affect my application?
Most applications will simply ignore the _comments object since it's just another JSON property. However, you should test this with your specific application to ensure compatibility.
Can I use this for configuration files?
Yes! This is particularly useful for configuration files, API responses, and data files where you need to document the purpose of each field for future reference or team collaboration.
Are there alternatives to adding comments in JSON?
Yes! You can use JSONC (JSON with Comments), JSON5, or YAML formats which natively support comments. However, if you must use standard JSON, the _comments approach is a practical workaround.
Is my data processed securely?
Yes, all processing happens in your browser. No data is sent to any server, ensuring your JSON content remains private and secure.
