Google Datastudio vs Explore: What are the differences?
Developers describe Google Datastudio as "A reporting and data visualization tool". It lets you create reports and data visualizations. Data Sources are reusable components that connect a report to your data, such as Google Analytics, Google Sheets, Google AdWords and so forth. You can unlock the power of your data with interactive dashboards and engaging reports that inspire smarter business decisions. On the other hand, Explore is detailed as "Free chart maker & visual exploration for spreadsheet data". It is a free online chart maker & visual data exploration tool for all your spreadsheet data (Excel, CSV, Google Sheets). It runs locally in your browser, and does not store your data in our servers - so, your data is absolutely safe.
Google Datastudio and Explore can be categorized as "Business Intelligence" tools.
