How this JSON Parser works

This tool parses JSON strings to validate their syntax and structure accurately. It checks for common errors like missing commas, unclosed brackets, or invalid data types, providing precise error messages with line numbers to help developers debug issues quickly. The parser also organizes the JSON data into a navigable tree structure, making it easier to explore deeply nested objects and arrays. It operates entirely client-side, ensuring that your data remains private and is never sent to a server.
