JSON objects (one per line) to CSV Converter

JSON Objects format (also called JSONL, JSON Lines, or Newline-Delimited JSON) stores one JSON object per line without wrapping them in an array. This format is common in:

• Log Files: Application logs, server logs, and audit trails often use one JSON object per log entry.
• Streaming Data: Data pipelines and message queues output one record per line for efficient processing.
• Big Data Exports: Tools like Elasticsearch, BigQuery, and analytics platforms export data in JSONL format.
• Machine Learning Datasets: Training data is often stored as JSON objects per line for easy streaming and processing.

{"name": "Alice", "age": 30, "city": "New York"}
{"name": "Bob", "age": 25, "city": "London"}
{"name": "Carol", "age": 35, "city": "Paris"}

Converting JSON Objects to CSV enables:

• Spreadsheet Analysis: Open in Excel or Google Sheets to filter, sort, and create pivot tables from your data.
• Quick Data Review: Scan through thousands of records visually without writing code to parse JSON.
• Sharing with Non-Technical Users: CSV is universally understood and doesn't require programming knowledge to use.
• Database Import: Import into SQL databases or data warehouses that accept CSV format.

The converter processes each line independently:

1. Each line is parsed as a separate JSON object
2. All unique keys across objects become CSV column headers
3. Each object becomes one CSV row
4. Missing fields result in empty cells

For Excel output, use our JSON Objects to Excel converter.

The output is standard CSV with:

• Header row with all field names from your JSON objects
• Proper escaping of commas and quotes in values
• UTF-8 encoding for international characters
• Configurable delimiter (comma, semicolon, tab)
