Statistical Data Format Converter — SAS, Stata, SPSS to CSV/Parquet

SAS, Stata, and SPSS have been the backbone of academic and government research for decades. But their file formats are proprietary, and the licenses are expensive. PondPilot reads all three — and converts them to modern, open formats — entirely in your browser.

Supported Statistical Formats

Format Extension Read Write To
SAS .sas7bdat ✅ CSV, Parquet, JSON, Excel
Stata .dta ✅ CSV, Parquet, JSON, Excel
SPSS .sav ✅ CSV, Parquet, JSON, Excel

All three formats are parsed by duckdb-read-stat, an open-source DuckDB extension maintained by the PondPilot team. It runs in WebAssembly — no server-side processing.

The License Problem

A SAS license can cost $10,000+/year. Stata ranges from $400 to $1,600. SPSS starts at $1,000+/year. If you just need to view or convert files in these formats, you shouldn’t need to pay for the full software suite. PondPilot is free and open source.

How to Convert

  1. Open app.pondpilot.io
  2. Drag in your .sas7bdat, .dta, or .sav file
  3. Inspect the data, run SQL queries if needed
  4. Export to your desired format

SQL-Powered Transformation

PondPilot isn’t just a blind converter. With DuckDB’s SQL engine, you can clean and reshape data during conversion:

SELECT patient_id, diagnosis_code, visit_date
FROM clinical_data
WHERE visit_date >= '2020-01-01'
ORDER BY patient_id, visit_date

Filter rows, select columns, rename variables, aggregate — then export the clean result.

Privacy for Sensitive Research Data

Statistical data files often contain protected health information, survey PII, or classified government data. PondPilot processes everything in your browser’s memory. Nothing is uploaded, nothing is logged, nothing leaves your machine.
