Hello My Masters & Colleagues, I have 3 columns of data in sheet2 (A) for Branches (B) for Departments and (C) for Names A2:c5000 like the table below the 3 lists are related and has some duplicates and blanks. And I have 3 Columns lets say J,K,L in sheet1 I want to J2:J each cell is validation drop down list from sheet2 (A) without Dup. and blanks, then depending to your choice it's create the validation list from sheet2 (B), then depending to your choice it's create the last validation list from sheet2 (C). any one have a solution for this deadlock, kindly avoid array formulas it's take too much time because the size of data
