Invalid JSON — Missing Closing Brace
Download a free JSON file with an intentionally missing closing brace. This tests whether your JSON parser correctly identifies unclosed objects, reports accurate error positions, and provides helpful error messages pointing to the exact location of the problem.
What Is Broken
The outermost closing brace '}' is missing, leaving the JSON object unclosed. Some nested objects are also intentionally left open to test multi-level error detection.
Broken Example
{
"config": {
"database": {
"host": "localhost",
"port": 5432,
"name": "mydb"
},
"cache": {
"ttl": 3600,
"driver": "redis"
}Why It Matters
Missing braces often occur in large JSON configuration files, API responses that get truncated during transmission, or when streaming JSON is interrupted. Your application needs to handle this gracefully.
Expected Parser / Validator Behavior
JSON.parse() throws 'Unexpected end of JSON input'. Python raises JSONDecodeError with position information. Well-implemented parsers indicate the last valid token position.

Frequently Asked Questions
How do I find missing braces in large JSON?
Use a JSON validator with line numbers and error position reporting. Our JSON Validator tool highlights the exact location of unclosed braces.
Can this happen with API responses?
Yes. Network timeouts, truncated responses, and streaming interruptions can all produce JSON with missing closing delimiters.
