In addition to PivotTables and Power Query, you can also consider using Excel's data analysis tools, such as filters, sorting, and conditional formatting, to gain insights from large datasets. Another approach is to use the Excel Data Model and create relationships between tables, enabling you to perform advanced analysis using the Power Pivot feature. Finally, you could explore implementing VBA macros to automate repetitive tasks and speed up the analysis process for large datasets.

One efficient way to analyze large datasets in Excel is by using PivotTables. PivotTables allow you to summarize and pivot your data quickly, making it easier to understand and identify patterns. Another approach is to use the Excel Power Query add-in, which enables you to import, transform, and analyze data from various sources. Additionally, you can leverage Excel's built-in functions and formulas, such as VLOOKUP, INDEX-MATCH, and SUMIFS, to perform complex analysis on your dataset.
