This preserves your hierarchical data in a flat table structure that's perfect for spreadsheets and databases.

Yes, our tool handles JSON arrays seamlessly. Each object in the array becomes a row in the CSV output, with consistent column headers derived from all unique keys across the objects. This is ideal for converting lists of records like products, users, or transactions from JSON to CSV format.

JSON5 is an extension of JSON that adds features like comments (// and /* */), trailing commas, multi-line strings, and unquoted keys. Our converter supports JSON5 natively, so you can work with more flexible JSON-like data formats without preprocessing. This is especially useful for configuration files and human-edited JSON data.

JSON Lines (JSONL) is a format where each line is a valid JSON object, commonly used for log files and streaming data. Our converter automatically detects and processes JSONL format, converting each line into a row in your CSV output. This makes it perfect for analyzing server logs, event streams, and other newline-delimited JSON data.

Our converter automatically handles special characters including commas, quotes, and newlines by properly escaping them according to CSV standards. Fields containing special characters are automatically quoted, ensuring your data imports correctly into Excel, Google Sheets, and database systems without manual cleanup.

Absolutely. Our JSON to CSV converter is ideal for processing API response data.
