Did You Know?
JSON stands for JavaScript Object Notation but is a language-independent data format.
Best Practice
Validate JSON before parsing it in your code to prevent application crashes from malformed data.
Q: Why is my valid JavaScript object failing as JSON? A: JSON is stricter than JavaScript; it requires double quotes for keys and forbids trailing commas.
Q: How do I find the exact line with an error? A: The validator provides line and column numbers, and clicking the error message will scroll the editor to that position.
Q: Does this support JSON Schema? A: Yes, you can validate against a schema to ensure your data follows a specific structure and data type set.
