Sheets and Input Table FAQs

Common questions about Sigma's spreadsheet experience.

What is Sigma’s Spreadsheet UI?

Sigma’s Spreadsheet UI is a spreadsheet-style way to work on warehouse data. The data stays in your warehouse, so you don’t need exports or extracts.

How are Sigma workbooks and sheets organized?

Workbooks are like spreadsheet files. Pages are like sheets (tabs), and a page can include tables, pivots, charts, filters, and text.

How do calculations work in Sigma?

Sigma is mostly column-based, not cell-by-cell. You define a calculation once and apply it across the dataset, with work pushed to the warehouse.

What are Input Tables, and what does “writeback” mean?

Input Tables let people add rows and edit values in Sigma. Those changes can be written back to a warehouse table so downstream work can use them.

When should I use an Input Table vs. modeling upstream?

Use an Input Table when the source of truth is human input like forecasts, assignments, approvals, or notes. Model upstream when values should be derived from systems or business logic.

How do Pivot Tables work in Sigma?

Pivot Tables summarize data across dimensions using live warehouse queries. You can group fields, add measures, show totals, and drill into details.
