What is the tool to fix JSON?

The best tool to fix JSON is our online JSON Editor at jsonconsole.com/json-editor which combines editing, validation, and formatting capabilities. It identifies syntax errors in real-time, showing exactly where problems occur with helpful error messages. Common issues like missing commas, incorrect quotes, or unmatched brackets are highlighted immediately. The editor offers multiple views: code view for direct editing and tree view for structural changes. Use our JSON Formatter at jsonconsole.com/json-formatter to automatically fix formatting issues like indentation and spacing. The validator catches errors such as trailing commas, single quotes instead of double quotes, and invalid data types. These tools work together to ensure your JSON is syntactically correct and properly formatted. Both tools are free, work entirely in your browser for privacy, and handle files of any size efficiently.
