Use OWOX Data Marts to collect raw data into your data warehouse, model it into reusable data marts, and then work with trusted data in Google Sheets – without rebuilding logic per spreadsheet.
Google Sheets is not where you build data pipelines. It's where your teams make decisions. OWOX delivers governed data marts directly into Sheets — so every number has a source, every metric has a definition, and every report refreshes itself.



Teams that use spreadsheets as their primary reporting interface — and need the numbers to be correct, explainable, and defensible in every meeting.

Spreadsheets are the most universal reporting tool in business. But when formulas, joins, and data imports live inside the sheet, they break. OWOX moves the logic to your data warehouse and delivers the result to Sheets — clean, fresh, and traceable. No per-connector fees, fully open-source, self-host anytime.

Connect as many sources as you need, all included

Fully available on GitHub — self-host anytime, your data stays yours

Every query, every schema, every schedule is visible and auditable


Every number in your spreadsheet traces back to a governed data mart — not a manual export or a broken formula.
Data marts refresh on schedule. No one has to click "refresh" or re-export a CSV before a meeting.
Analysts define metrics once in SQL. Business teams consume them in Sheets without breaking anything.
One data mart feeds Sheets, Looker Studio, and AI Insights. Same number everywhere — no reconciliation.
Walk into any standup or board meeting with a spreadsheet that proves every metric. No dashboard, no screenshot — just the data.
When every spreadsheet runs on the same governed data marts, teams stop debating and start acting.

BI tool
Finally, a tool that doesn't ask business users to learn a new dashboarding UI. Our marketing team already knows Sheets. OWOX just delivers the right data.
Joinable data marts concept was the thing that sold us. We can now use the semantic layer without building one.
