Written in ranges, not cells
Values are written as ranges, so large refreshes do not thrash the sheet.
Google Sheets
Polytomic connects Google Sheets to your data warehouse, databases, and SaaS tools for ETL and reverse ETL. Push query results from your data warehouse into a tab on a schedule, and read spreadsheet data back out into your CRM or data warehouse, without writing code.
Formatting survives
Replace clears values rather than structure, so formats and validation stay.
Read and write tabs
Use a sheet as a source for your data warehouse, or as a reporting destination.
Example workflows
Push data warehouse query results into a reporting tab
What you can sync
Move data between Google Sheets and your data warehouse, databases, and SaaS tools, reading a tab as a table and writing results back into one.
From Google Sheets
Each grid tab exposed as its own table
Header rows detected from frozen rows or a header setting
Numeric, date, and boolean type hints from validation rules
Paged reads with duplicate row removal
To Google Sheets
Replace, rewriting the mapped columns each run
Append, adding rows after the last populated one
All discovered columns available as write targets
Automatic row expansion when the tab runs out of rows
How it works
Connect a spreadsheet and Polytomic exposes each grid tab as a table. From there a tab can be a source feeding your data warehouse or CRM, or a destination that a scheduled query refreshes, which is how teams give people live numbers without giving them warehouse access.
Writes go in as ranges rather than cell by cell, which matters at scale: tools that populate a sheet one cell at a time force Sheets to recalculate constantly and struggle well before you reach interesting row counts.
- Connect with OAuth or a service account and select a spreadsheet
- Each grid tab becomes a table you can select
- Headers come from frozen rows or the columns have headers setting
- Write with replace or append
- Existing formatting and data validation are preserved
- Monitor sync health, record volume, and failures from one interface
How to set up
Polytomic supports user OAuth and service account credentials. With a service account you must share the spreadsheet with the service account address as an editor, since it has no implicit access. A connection is bound to one spreadsheet, so syncing several means several connections.
How to get connected
- 1In Polytomic, navigate to Connections, then Add Connection, then Google Sheets
- 2Authorize with OAuth, or paste a service account key
- 3If using a service account, share the spreadsheet with it as an editor
- 4Select the spreadsheet
- 5Enable columns have headers, or freeze your header row
- 6Test the connection and click Save
