Convert SAS to Parquet Online — Modernize Legacy Data

Parquet is the standard for modern data infrastructure. SAS .sas7bdat is a legacy format tied to expensive proprietary software. PondPilot bridges the gap — convert SAS files to Parquet directly in your browser, no license required.

Why Convert SAS to Parquet?

  • Columnar storage — Parquet files are dramatically smaller and faster to query
  • Universal compatibility — works with Spark, DuckDB, Pandas, Polars, BigQuery, Snowflake
  • Typed columns — preserves data types better than CSV
  • Free from vendor lock-in — no SAS installation needed to read the output

How to Convert

  1. Open app.pondpilot.io
  2. Drop in your .sas7bdat file
  3. Optionally transform with SQL (rename columns, filter rows, cast types)
  4. Export as Parquet

PondPilot uses duckdb-read-stat to parse SAS files and DuckDB’s native Parquet writer for output. The entire pipeline runs client-side via WebAssembly.

Transform During Conversion

This is where PondPilot shines compared to blind conversion scripts. You can clean up the data during conversion:

SELECT
  LOWER(region) as region,
  amount::DOUBLE as amount,
  date_col::DATE as event_date
FROM sas_data
WHERE region IS NOT NULL

Rename columns, fix types, filter junk — all before the Parquet file is written.

Data Migration Use Case

If your organization is moving off SAS, PondPilot is a quick way to convert individual datasets without standing up a conversion pipeline. Analysts can self-serve: open the SAS file, verify the data looks right, export to Parquet, and upload to the new system.

Privacy

SAS datasets in healthcare and pharma often contain protected health information. PondPilot runs entirely in your browser — nothing is uploaded, nothing is logged. Your data stays on your machine.
