Display all matching values in one comma separated cell
问题 I have two columns of data in an Excel 2010 spreadsheet. In Column A is a category, and in Column B is a value. There will be multiple values in Column B for each unique category in Column A. What I want to achieve in a separate sheet is to display all of the values for each each unique category in one comma (or semi-colon etc) separated cell. For example, if my first sheet looks like this: ---------------------- | Category | Value | ---------------------- | Cat1 | Val A | | Cat1 | Val B | |
