About Parquet Data
Apache Parquet is a columnar storage format widely used in data engineering, big data pipelines, and cloud data warehouses like Snowflake, BigQuery, and AWS Athena. CleanChart supports importing data from Parquet file exports — convert your Parquet files to CSV using tools like pandas, DuckDB, or your data platform's export feature, then upload to CleanChart for instant visualization.
Parquet files are the standard output format for Spark jobs, dbt models, and ETL pipelines. When you need to visualize the results of a data pipeline — aggregation outputs, model training metrics, or pipeline monitoring data — exporting to CSV and uploading to CleanChart is the fastest path from data warehouse to publication-ready chart.
