What are the steps to convert a JSONL file to CSV?

1. Open the JSONL to CSV converter page. 2. Upload your .jsonl file or paste the JSONL data. 3. Click 'Convert' and wait for the tool to parse and flatten the JSON objects. 4. Download the resulting CSV file. The tool automatically detects field names, flattens nested structures, and handles arrays to preserve all data.

Why should I convert JSONL to CSV instead of keeping JSONL?

CSV is a universal tabular format widely supported by spreadsheet applications (Excel, Google Sheets), database imports, and legacy systems. JSONL is better for streaming and structured data, but CSV's column-based layout makes it easier for humans to inspect, filter, and analyze records, and often reduces file size by removing duplicate keys.

How does the converter handle nested objects and arrays in JSONL?

Nested objects are flattened using dot notation (e.g., user.address.city becomes a separate column). Arrays are serialized as JSON strings in the cell if they contain non-scalar values; for simple arrays of primitives, we expand them into multiple rows when possible to maintain a fully tabular structure. This ensures no data is lost and the output remains compatible with CSV consumers.
