How can I find duplicate values in Excel without deleting them?

In order to find duplicate values in Excel without deleting them, one can use the built-in “Conditional Formatting” tool. This tool allows users to highlight duplicate values within a selected range of cells, making it easier to identify and work with these values. Additionally, the “Remove Duplicates” feature can be used to extract the duplicate values into a separate column, without deleting the original values. This allows users to have a clear overview of the duplicate values in their data, while still retaining the original data for analysis and reference purposes.
