How to write JSON code?

Writing JSON code requires following specific syntax rules. Start with curly braces {} for objects or square brackets [] for arrays. Use double quotes for all keys and string values—single quotes are not valid. Separate key-value pairs with colons and multiple pairs with commas. For example: {"name": "John", "age": 30}. Do not include trailing commas after the last item. JSON supports six data types: strings, numbers, booleans (true/false), null, objects, and arrays. Use our JSON Editor at jsonconsole.com/json-editor to write JSON with real-time validation that catches syntax errors immediately. The editor provides helpful error messages and automatic formatting. Practice by creating simple objects first, then progress to nested structures. Always validate your JSON using our validator to ensure it meets syntax requirements before using it in applications.
