Two interfaces for the same Snowflake tables
Sigma and CoWork are a natural pairing for Snowflake customers. Sigma has deep Snowflake roots and queries live warehouse tables rather than extracts, and CoWork works on governed data inside Snowflake by definition. Neither moves data elsewhere. The real question is which interaction model suits your users: building in a spreadsheet, or asking in a sentence.
Sigma's answer is the spreadsheet. Finance and operations analysts already know formulas, pivots, and grids, and Sigma gives them that experience on warehouse-scale data, plus input tables and dashboards for sharing. Adoption can be quick among spreadsheet-comfortable users. As usage spreads, workbook sprawl and inconsistent formulas need standards from the data team to keep under control. On BI Bench, Sigma placed ninth with 35.2% accuracy and a 42.6-second average.
