SAS2PY converts SAS and SQL dialects directly to Snowflake — Snowpark, Dynamic Tables, Streams & Tasks, Snowflake Cortex AI, and Virtual Warehouses — with +95% parsing accuracy and column-level lineage.
Snowflake Targets
Every modernization generates production-ready Snowflake artifacts — leveraging Snowpark, Dynamic Tables, Streams & Tasks, Zero-Copy Cloning, Snowflake Cortex, and the Snowflake Data Cloud.
Legacy ETL logic converted to Snowpark Python DataFrames — pushdown computation runs natively inside the Snowflake Virtual Warehouse, no data movement required.
Incremental transformation pipelines rewritten as Snowflake Dynamic Tables — declarative SQL with automatic refresh, lag targets, and full lineage tracking built in.
CDC patterns and scheduled ETL converted to Snowflake Streams (change capture on tables/views/stages) and Tasks (DAG-based orchestration with serverless compute).
Batch and near-real-time data ingestion replatformed to Snowpipe with auto-ingest from S3/Azure/GCS — replacing legacy file-based ETL landing patterns.
SAS analytical and scoring models converted to Snowflake Cortex — LLM functions (COMPLETE, SUMMARIZE, CLASSIFY), ML classification, regression, and anomaly detection inside Snowflake.
Workload-specific Virtual Warehouse sizing recommendations generated per pipeline — separating ETL, reporting, and ad hoc query workloads with auto-suspend/resume.

Before you modernize, map your estate. Compass extracts column-level lineage, STTM, and dependency graphs from any source — and publishes them directly into the Snowflake object catalog for governance.
How It Works
The same proven methodology applies to every source — SAS — all landing natively on Snowflake.
Upload source artifacts — SAS scripts — into SAS2PY for parsing.
Custom parsers build complete ASTs, expand macros, resolve dependencies, and produce column-level lineage — with Snowflake-readiness scoring.
Parser-driven conversion to Snowpark Python, Dynamic Tables, Snowflake SQL, Tasks DAGs, or Snowpipe — with auto documentation and Snowflake best-practice patterns.
Row-level and aggregate data matching between legacy and Snowflake outputs — using Snowflake-native comparison queries for audit-ready sign-off.
Publish lineage, STTM, and data contracts to the Snowflake object catalog. Merlin AI surfaces risk and recommends clustering, materialization, and Virtual Warehouse sizing.

Frequently Asked Questions
Common questions from teams evaluating SAS2PY for Snowflake modernization programs.
Snowflake-native. SAS2PY generates Snowpark Python with full pushdown execution inside Virtual Warehouses, Dynamic Tables with declarative refresh, Streams & Tasks DAGs, and Snowflake SQL — not generic Python or Spark code adapted for Snowflake.
SAS2PY analyzes the source pipeline pattern and recommends the optimal target: Dynamic Tables for declarative incremental refresh with target lag, Streams & Tasks for event-driven CDC with complex DAG dependencies. Both are generated automatically — the choice is based on parsed source semantics.
Yes. SAS2PY produces column-level STTM (Source-to-Target Mapping) tables and publishes them to the Snowflake object catalog with data classification TAGs, row access policies, and masking policies — providing full governance from day one of the modernization.
Yes. SAS PROC LOGISTIC, PROC GLM, PROC MIXED, and PROC MODEL are converted to Snowflake Cortex ML functions — classification, regression, anomaly detection, and forecasting — running natively inside Snowflake with no external compute required.
Legacy job schedulers (Control-M, Autosys, SAS batch flows) are converted to Snowflake Tasks with DAG dependencies, serverless compute, retry logic, and cron-based scheduling — or to Dynamic Tables with automatic refresh targets.
Yes. Complex legacy logic that cannot be expressed as pure SQL is converted to Snowpark Python UDFs, UDTFs (for table-returning functions), and Stored Procedures — all executing natively inside the Virtual Warehouse with full pushdown.
Yes. SAS2PY supports full on-premise and air-gapped deployment. Source code, lineage data, and metadata never leave your network. Zero-Copy Cloning is used for environment promotion (dev → test → prod) without data duplication.
SAS2PY generates row-level and aggregate-level data comparison queries that run natively in Snowflake — comparing legacy output against Snowflake-produced output. Validation includes row counts, column checksums, business rule assertions, and statistical parity proofs for audit-ready sign-off.
