Hi Guys, there is duplication of trade IDs in an Excel spreadsheet I have. If I have a trade Id "567893.28" for example. How can I count how many times this appears in Column "C"? Is it a "Countif" formula? If I have the Value in the Cells ("F1") and I want to find out how many times that appears in Column C, what would be the formula?

If you have multiple IDs duplicated, you could you the contingency table (visual group by SQL equivalent in Excel) to find out which IDs and how many times are duplicated. Then you can use the countif to search for one after another.
