In my experience, Google Sheets has been an invaluable tool for managing and analyzing data. I have extensively used formulas to automate calculations and streamline data processing. For instance, I often utilize functions like VLOOKUP and INDEX-MATCH to efficiently retrieve and cross-reference data. Additionally, pivot tables have been instrumental in summarizing large datasets and identifying trends. By creating pivot tables, I can quickly generate insightful reports that help in decision-making. I've also used features like slicers and charts to enhance data visualization, making it easier to communicate findings to stakeholders.
