Question 1

What is RFC 8259 compliance?

Accepted Answer

RFC 8259 is the official JSON specification that defines the exact rules for valid JSON. Our validator checks that your JSON strictly follows these rules, including proper use of double quotes, no trailing commas, correct data types, and proper nesting.

Question 2

What are the most common JSON errors?

Accepted Answer

The most common errors include: trailing commas after the last item in arrays or objects, using single quotes instead of double quotes, unquoted property names, missing commas between items, and mismatched brackets or braces.

Question 3

Can this validator fix my JSON automatically?

Accepted Answer

No, the validator identifies errors and tells you exactly where they are (line and column number), but you need to manually fix them. This ensures you understand the issues and maintain control over your data structure.

Question 4

Is my JSON data sent to your servers?

Accepted Answer

No! Our JSON Validator runs entirely in your browser using client-side JavaScript. Your data never leaves your device, ensuring complete privacy and security for sensitive information like API keys or configuration data.

Question 5

What's the difference between a validator and a formatter?

Accepted Answer

A validator checks if your JSON is syntactically correct and follows the JSON standard, reporting any errors. A formatter beautifies valid JSON by adding indentation and whitespace for readability. Use a validator to find and fix errors, then use a formatter to make it readable.
