# Help writing formulas in excel

Excel has to follow the same rules as mathematics. Order precedence means the order in which the computer calculates the answer. So you have to understand the order precedence when you write a formula. Could you help clarify if there blank values? Screenshot examples would be helpful. Hopefully one of them will get you where you need to go. Note that the first one ignores the request to do this as a formula since that solution is not pretty. A unique list is created either in place or at a new location.

Note that you can record this action to create a one line VBA script to do this which could then possible be generalized to work in other situations for you e. The list must be sorted ascending or descending does not matter. Three new columns are required two new columns for calculations and one new column for the new list.

Here is the summary of the solution: For each item in the list, calculate the number of duplicates above it. For each place in the unique list, calculate the index of the next unique item. Finally, use the indexes to create a new list with only unique items. And here is a step by step example: Open a new spreadsheet In a1: In column B, calculate the duplicates: Use smart copy to populate the rest of column B: Move your mouse over the black square in the lower right hand corner of the selection.

Click and drag down to the bottom of the list B6. When you release, the formula will be copied into B2: B6 with the relative references updated.

The value of B1: B6 should now be "0,0,1,0,0,1". Notice that the "1" entries indicate duplicates. In Column C, create an index of unique items: The "if" is being used to stop a REF from being produced when the index reaches the end of the list.

Use smart copy to populate C3: The value of C1:A collection of useful Excel formulas for sums and counts, dates and times, text manipularion, conditional formatting, percentages, lookups, and more!
