Understanding JSON Validation
Common JSON Errors: Missing commas between properties, trailing commas after the last element, unquoted keys, single quotes instead of double quotes, and unescaped special characters in strings.
Valid JSON Requirements: Keys must be strings in double quotes. Values can be strings, numbers, booleans (true/false), null, arrays, or objects. No comments are allowed in standard JSON.
Analysis Features: This validator provides detailed statistics including the number of keys, nesting depth, and counts of different value types (strings, numbers, booleans, arrays, objects, and nulls).
