I've used Google Sheets to automate repetitive tasks. By combining functions like IMPORTRANGE, QUERY, and ARRAYFORMULA, I've built a system that pulls data from multiple sources, performs calculations, and generates reports automatically.

One innovative use case I discovered for Google Sheets is using it as a project management tool. With custom scripts and add-ons, I've built a comprehensive project tracker that automatically generates tasks, assigns deadlines, and sends notifications to team members.

In my work, I've found that Google Sheets is a powerful tool for data visualization. I use conditional formatting and data validation to create interactive dashboards that allow stakeholders to explore and analyze the data in real-time.

One interesting use case I've come across is using Google Sheets for A/B testing. By leveraging the power of Google Sheets' collaboration features, multiple team members can work on different test variations simultaneously, making it easier to compare and analyze the results.

I've seen Google Sheets being used as an inventory management tool. By integrating it with Google Forms and Google Apps Script, users can easily submit their inventory updates, which are then consolidated and tracked in a centralized spreadsheet.
