Why Use a JSON5 Validator?

• Save Time: Don’t waste hours hunting for a missing comma or bracket. We find it for you in seconds.
• Ensure Accuracy: Guarantee that your configuration files or data structures are error-free before you deploy them.
• Learn Faster: If you are new to JSON5, seeing exactly where you went wrong helps you learn the syntax better.

Common Use Cases

• Configuration Files: JSON5 is perfect for config files (like .json5 or .rc files) because you can add comments. This tool checks them before use.
• Debugging: Quickly isolate syntax errors when your app throws a parsing error.
• Data Exchange: Verify data formats before sending them between a server and a web application.

Features

• File Upload Support: No need to copy-paste huge files; just upload them directly.
• Instant Validation: Get real-time feedback on your syntax.
• Clean Interface: Distraction-free design so you can focus on your code.
• One-Click Clear: Easily wipe the editor to start a new task.

Frequently Asked Questions (FAQs)

1. What is the main difference between JSON and JSON5?

The biggest difference is flexibility. Standard JSON is very strict—you can’t have comments or trailing commas. JSON5 is designed for humans; it allows you to add comments (// or /* */), use trailing commas, and even use unquoted keys, making it much easier to write and read.

2. Why does my code work here but fail in a standard JSON parser?

Because JSON5 includes features that standard JSON doesn’t support (like comments). If you are trying to feed this code into a system that only understands strict JSON, you will need to remove the comments and fix the commas first.

3. Can I validate files directly from my computer?

Absolutely. If you have a large configuration file, you don’t need to copy and paste everything. Just click the “Upload File” button to load your .json or .json5 file directly into the editor for checking.

4. Does this tool support comments?

Yes! That is one of the best features of JSON5. You can use single-line comments (starting with //) and multi-line comments (wrapped in /* ... */) to leave notes in your code, and this tool will mark them as valid.

5. What do I do if the validator finds an error?

If the tool finds an issue, it will usually highlight the specific line number or give you an error message describing what went wrong (like a missing bracket or an invalid character). Simply check that line, fix the typo, and hit “Validate” again.
