Ditch Looker/Tableau: Build a Live Executive BI Dashboard in Google Sheets

A guide shows how Google Sheets can serve as a low-cost BI stack with three layers: raw data, transformation, and an executive dashboard.

It uses Apps Script to load data, formulas like QUERY to reshape it, and charts plus slicers to create a polished live view.

When data grows beyond spreadsheet limits, the article recommends Connected Sheets with BigQuery for scalability.

The approach is pitched as a faster, cheaper alternative to tools like Tableau, Power BI, and Looker for many teams already using Google Workspace.
