We're excited to announce support for Apache Parquet and JSON Lines (JSONL) formats. These formats are essential for modern data engineering, analytics pipelines, and machine learning workflows. Whether you're working with data lakes, preparing datasets for analysis, or building ETL pipelines, our new converters make it easy to transform data between formats without writing code.
What is Apache Parquet?
Apache Parquet is a columnar storage file format designed for efficient data storage and retrieval. It's widely used in big data ecosystems including Apache Spark, Apache Hadoop, Amazon Athena, Google BigQuery, and Snowflake.
Columnar storage means data is stored column by column rather than row by row. This makes Parquet ideal for analytical queries that only need specific columns, resulting in faster query performance and reduced storage costs.
Key Benefits of Parquet:
Efficient compression: Achieves high compression ratios, reducing storage costs
Fast queries: Columnar format enables reading only required columns
Schema preservation: Maintains data types and nested structures
Wide compatibility: Supported by all major data platforms
What is JSON Lines (JSONL)?
JSON Lines (also known as JSONL or Newline Delimited JSON) is a text format where each line is a valid JSON object. It's perfect for streaming data, log files, and datasets that need to be processed line by line.
One JSON object per line makes JSONL ideal for processing large datasets without loading everything into memory. Each line can be parsed independently, enabling efficient streaming and parallel processing.
Key Benefits of JSONL:
Streaming friendly: Process one record at a time without loading entire file
Easy to append: Add new records by appending lines to the file
Human readable: Plain text format that's easy to inspect and debug
ML/AI ready: Standard format for training datasets and model outputs

Common Use Cases
Machine Learning Datasets
Prepare training data in JSONL format for OpenAI fine-tuning, or convert model outputs back to spreadsheets.
Data Lake Integration
Convert legacy data formats to Parquet for storage in modern data lakes on AWS S3, Azure Data Lake, or Google Cloud Storage.
Log Processing
Convert JSONL log files to CSV or Excel for analysis in spreadsheet tools, or to Parquet for long-term archival.
Data Exchange
Share data with partners in their preferred format. Convert between Parquet, JSONL, CSV, and Excel as needed.
How It Works
1
Upload Your File
Select the converter you need and upload your source file. We support files up to 100 GB with our enterprise plans.
2
