What is JSON and Why Should You Validate It?
JSON is a simple and readable format for storing and exchanging data. It looks like a mix of JavaScript code and plain text. JSON is often used in:
-
REST APIs
-
Web applications
-
Configuration files
-
Mobile apps
-
Data sharing between servers
But JSON must follow a strict structure. If you skip a quote or forget a closing bracket, the entire file may fail to load. That’s why validating JSON is essential.
A json validator online tool checks whether your JSON code follows the correct syntax and structure. If there are issues, it highlights them so you can correct them instantly.
Common JSON Errors Developers Face
Even experienced developers face basic syntax errors. Some of the most common include:
-
Missing commas between values
-
Unquoted keys or strings
-
Extra or missing brackets
{}or[] -
Using trailing commas (which are not allowed in JSON)
-
Incorrect use of boolean or null values
These small mistakes can cause major issues if not fixed early. A reliable json formatter validator helps you catch these problems on the spot.

Easy to access from any device
