Duplicate entries in your Excel lists? This distorts your data. Our tutorial shows you, using a practical example, how to clean up your data in seconds with the "Remove Duplicates" function – whether you want to delete identical rows or just values ​​in a column.

The OFFSET function in Excel creates a flexible reference. Instead of fixing =SUM(B5:B7), the function finds the range itself, e.g., for the "last 3 months". Ideal for dynamic charts or dashboards that grow automatically.

The INDIRECT function in Excel converts text into a real reference. Instead of manually typing =January!E10, use =INDIRECT(A2 & "!E10"), where A2 contains 'January'. This allows you to easily create dynamic summaries for multiple worksheets.
