JSON Formatter, Validator & Beautifier
Beautify, validate, and minify JSON payloads instantly. Detect exact syntax errors by line and column, sort keys alphabetically, and inspect collapsible tree nodes.
Understanding JSON Standards and Best Practices
JSON (JavaScript Object Notation) is the ubiquitous data interchange format for modern APIs:
Unlike JavaScript object literals, RFC 8259 requires that all string values and object property keys be enclosed in double quotes (`"key": "value"`).
Standard JSON parsers reject trailing commas after the final element in an array or object. Our validator instantly flags these errors.
Frequently Asked Questions
Is my confidential JSON data uploaded to remote servers?
Never. Kagazo processes all JSON parsing, formatting, and validation 100% locally in your browser’s JavaScript V8 engine memory. No payloads are ever transmitted across network connections.
How does Kagazo detect JSON syntax errors?
When an invalid JSON string is supplied, our parser calculates the exact byte offset and maps it to line and column coordinates, highlighting missing brackets, trailing commas, or unquoted keys.
Can I sort JSON object keys alphabetically?
Yes! Use the "Sort Keys" feature to recursively sort all object keys from A to Z, making diffing and version comparisons effortless.
What is the difference between 2-space and 4-space indentation?
2-space indentation is the modern standard used by JavaScript, TypeScript, and Google style guides to maintain readability in deeply nested objects. 4-space is common in Python and Java environments.
