Extract unique values by using array formula
There are formulas for you to extract unique distinct values (including first duplicates) and unique values (excluding first duplicates).
Note: With formulas to solve the extracting is a little difficult and complex, if you want to extract unique values correctly and sympely, I suggest you to apply the second and third methods.
Extract unique distinct values (including first duplicates)
Select a blank cell, here I select C2, and enter this formula =IFERROR(INDEX($A$2:$A$8, MATCH(0, FREQUENCY(IF(EXACT($A$2:$A$8, TRANSPOSE($C$1:C1)), MATCH(ROW($A$2:$A$8), ROW($A$2:$A$8)), ""), MATCH(ROW($A$2:$A$8), ROW($A$2:$A$8))), 0)), "") ($A$2:$A$8 is the list range of the values you want to extract from, $C$1:C1 is the first cell of the column you want to put out the extracting result), press Shift + Ctrl + Enter buttons, then drag fill handle to fill the range you need. You can see the unique distinct values (including first duplicates) are extracted only:
Extract unique values (excluding first duplicates)
Before you using the formula, you need to define a name for the values range.
1. Select the range, for instance, A2:A8, and click Formula > Define Name. See screenshot:
2. In the New Name dialog, type a name for your range in the Name text box and then click OK to close the dialog. See screenshot:
3.Select a blank cell, here I select C2, type this formula =INDEX(List, MATCH(0,INDEX(COUNTIF(C1:$C$1, List)+(COUNTIF(List, List)<>1),0,0), 0)) (C1:$C$1 is the first cell of the column you want to put out the extracting result, and the List is the range name you defined in the second step ), press Shift + Ctrl + Enter buttons, then drag fill handle to fill the range you need. You can see the unique values (excluding first duplicates) are extracted only:
Note: If you drag the fill handle and fill the cells more than the number of unique values, the excess cells display as error #N/A. Just clear these errors.
Extract unique values (including first duplicates) by using Advanced Filter
In Excel, you can use Advanced Filter function to extract unique distinct values (including first duplicates) only.
1. Select the list range you want to extract unique distinct values from (including the list label), and click Data > Advanced. See screenshot:
2. In the Advanced Filter dialog, check Copy to another location, then select a single cell to put out your result values, and check the Unique records only. See screenshot:
3. Click OK, you can see the result:
