🔬Mini Tutorial
JSON 到 CSV 转换原理This tool uses advanced JSON parsing algorithms to convert complex JSON structures into CSV format. It handles nested objects by flattening them with dot notation, processes arrays by converting them to comma-separated values, and provides flexible delimiter options for different CSV standards. The conversion preserves data integrity while making it compatible with spreadsheet applications and data analysis tools.
嵌套对象处理当启用'展开嵌套对象'选项时，工具会将嵌套的 JSON 对象转换为扁平结构，使用点符号连接键名。例如：contact.email 表示 contact 对象中的 email 字段。
数组和特殊值处理数组值会被转换为逗号分隔的字符串，并用引号包围。对象值会被序列化为 JSON 字符串。包含特殊字符的值会自动添加引号和转义。
分隔符和排除键支持多种分隔符以适应不同的 CSV 标准。排除键功能允许您过滤掉不需要的字段，提高数据处理的灵活性。
