About JSON Formatter
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate.
- Syntax Rules: Data is in name/value pairs, separated by commas, curly braces hold objects, square brackets hold arrays
- Data Types: Strings, numbers, booleans, arrays, objects, null
- Common Uses: APIs, configuration files, data storage, web services
- Validation: JSON must be properly formatted with correct syntax
- Formatting: Improves readability with proper indentation and line breaks
Example JSON Structure:
{
"name": "John Doe",
"age": 30,
"active": true,
"tags": ["user", "premium"],
"address": {
"street": "123 Main St",
"city": "Anytown"
}
}
