I'm working with an Excel file containing over 100,000 records, and duplicate entries are causing reporting issues. Excel's built-in Remove Duplicates feature isn't giving me the flexibility I need because I want to compare multiple columns before deleting anything. While searching for alternatives, I came across the <strong data-start="676" data-end="718">SysTools Excel Duplicates Remover Tool. Has anyone used it for large datasets? I'm interested in knowing if it accurately identifies duplicates, preserves the original formatting, and allows selective removal without affecting unique records.
