JSON (JavaScript Object Notation) is a lightweight data format used for storing and exchanging data. It's commonly used in web APIs, configuration files, and data storage.
Formatted JSON is easier to read and debug. Proper indentation helps you understand the structure of nested objects and arrays, making it easier to spot errors or find specific values.
We collect only metadata (tool usage, data sizes, timing) - your actual data is never logged or stored.
Our Fix JSON feature can automatically repair trailing commas, single quotes (converting to double quotes), unquoted keys, missing quotes around string values, and common JavaScript-style comments.
