A JSON formatter is an online tool that formats JSON (JavaScript Object Notation) data into a readable format and validates syntax errors. It helps developers work more efficiently with JSON data.
'Format' adds line breaks and indentation to make JSON human-readable. 'Minify' removes unnecessary whitespace and line breaks to minimize file size.
Commonly, 2 or 4 spaces are used. Choose based on your project's coding standards or your preference for readability.
Files can be processed within browser limitations, but very large JSON files (several MB or more) may take longer to process.
Syntax errors are automatically detected and displayed with error messages. Validation also runs when you move focus away from the input field.
No, all processing is done entirely within your browser and no data is sent to any server. Your privacy and security are guaranteed.
