JSON Validator & Parser
The JSON validator lets you check whether a JSON document is syntactically correct. The tool analyzes the data structure and indicates formatting errors, allowing you to quickly fix any invalid entries.
JSON (JavaScript Object Notation) is a popular data exchange format used in APIs, web applications and system configurations. A correct JSON structure is essential for many web services to function properly.
How does the JSON validator work?
To validate JSON, simply paste the data into the editor. The tool automatically analyzes the document structure and detects syntax errors such as missing commas, unclosed brackets or invalid quotation marks.
- checking JSON syntax validity
- syntax highlighting for easier reading
- indicating where the error occurs
- editing and testing JSON data
Most common JSON errors
Invalid JSON most commonly results from minor syntax errors. The JSON validator helps you find and fix them quickly.

Example of valid JSON
Below is an example of a correctly written JSON document. Each element consists of a key–value pair, and the data is stored in an object or array structure.
{
"name": "John Smith",
"email": "[email protected]",
"active": true,
"roles": ["admin", "editor"],
"address": {
"city": "London",
"country": "United Kingdom"
}
}The JSON validator lets you check whether similar data is syntactically correct and whether the document structure contains no errors.
