Familiar on day one
Spreadsheet functions, pivots, and formatting on billions of rows.
Writes land in the warehouse
Input Tables and Sigma Tables store entries in your warehouse instead of in a file someone emails around.
An audit trail on every change
See who changed what and when, row by row.

One live copy
The real process lives in a file
Targets, forecasts, and corrections sit in spreadsheets on a shared drive. Copies drift from the warehouse, and nobody can say who changed what.
| Today | With Sigma |
|---|---|
| Exports pasted in by hand each week | Formulas and pivots on live data with no export |
| Copies emailed around until nobody knows which is current | One table your team edits at the same time |
| Edits that never make it back to the warehouse | Entries written back to Snowflake or Databricks |
| No record of who changed a number or when | Changes logged with who made them and when |
Built for the people who live in spreadsheets
Finance, operations, and data teams work in the same table at the same time, and each edit is saved with who made it.
Finance and planning teams
Enter targets, forecasts, and adjustments next to the actuals, without rebuilding the file each month.
Operations and business teams
Add corrections and notes beside the live rows, so the context stays with the number.
Data and IT leaders
Retire the shared-drive files and see who changed what, with writes governed.
Why teams move the spreadsheet to Sigma
No extracts to refresh, copies to merge, or files that stall at a million rows. People keep the grid they know, and the data stays where IT can govern it.
No row limits
Spreadsheet functions on billions of rows
Write formulas with the functions people already know, and Sigma runs them on the full live warehouse table, so nobody waits on a refresh or hits a row limit.
- 200+ functions, with help as you type
- No file size limits
- Live data, never a snapshot
Live pivots
Pivot tables that never need a refresh
Drag fields into a pivot table the way you would in Excel, and Sigma builds it on live warehouse data. Subtotal, regroup, and drill into the rows behind any number.
- Rows, columns, and values by drag and drop
- Subtotals and grand totals on the full data
- Drill from any cell to the detail behind it
Tagged in place
Sort thousands of comments with one AI Column
Write a prompt the way you’d write a formula, reference the column it reads, and Sigma fills in each row. Pivot or chart the new column like any other. AI Columns are in beta.
- Reference a column in the prompt
- Preview the first 100 rows before it runs
- Only new or changed rows re-run
Straight to the warehouse
Entries land in your warehouse
Type a forecast, note, or correction into an Input Table beside live numbers. On save, it’s written to your warehouse with who changed it and when, ready for dashboards and pipelines.
- Written to Databricks, Snowflake, and other warehouses
- Who changed what, and when, row by row
- Ready for dashboards, models, and pipelines
Apps in sync
An edit in one app shows up in the others
Each team’s app reads and writes the same Sigma Table, governed by your warehouse. An employee confirms a shift in their portal and their manager sees it, with no copies to sync.
- Apps read and write the same records
- No sync jobs, exports, or duplicate copies
- Warehouse security and audit logging apply
Control who writes, where, and when
Writes follow the same permissions and table policies as reads, and changes are logged.
Write permissions
Decide where each Input Table takes edits, in the draft or the published version, based on workbook access.
Per-user OAuth
Connect with OAuth so queries run with each person’s own warehouse role.
Row- and column-level security
Reads and writes both inherit your table policies.
Audit trail
Audit logs record user activity, AI conversations, and input table edits, so you can see who changed what.
Your data stays put
Sigma queries your warehouse in place and never copies the data out.

Spreadsheets and writeback FAQ
Can Sigma replace Excel for our team?
For work that depends on shared, current data, yes. People keep the spreadsheet interface, and the data stays in the warehouse instead of in files.
Where does data entered in Sigma go?
Input Tables write to your warehouse, next to the source data.
Is there a row limit like a spreadsheet file?
No file limit applies, because Sigma runs on your warehouse.
Who can write data?
Only people you grant edit access to, under the same permissions and table policies as everything else in Sigma.
Are changes tracked?
Yes. Input Tables keep a change history, so you can see who changed what and when.
What are Sigma Tables?
Sigma Tables are tables in your warehouse that any Sigma workbook can read and write, so several apps can share one table. Because they live in the warehouse, its security and audit logging apply.
