Return Sorted Unique List of Values from Column having only Text or only Numbers

 


 

Sort Column values in Ascending / Descending Order, Retain Duplicates or Extract only Once (ie. Uniques) 

 

Column F: Extracts Uniques & Sorts column E values in Ascending order - column E can have ONLY Numbers. Enter Array formula (Ctrl+Shift+Enter) in cell F2 and copy down.

  

Note: If cell F2 formula is in a different column, replace "F$1:F1" in the formula with that column (ex. if formula is in column D then update to "D$1:D1").

In Column F, return Unique & Sorted column E values in Ascending order - column E can have ONLY Numbers - Array formula.

  

Extract Unique Values in Ascending Order

  

Cell F2 formula:

 

=IFERROR( SMALL( IF( COUNTIF( F$1:F1, E$2:E$20)+ (E$2:E$20="")=0, E$2:E$20), 1), "") 

 

Explanation - Cell F2 formula (Array formula):

 

1) COUNTIF(F$1:F1, E$2:E$20): counts values of column A in the preceding cells of the formula column (column F) as the formula gets copied down. It returns an array of 1s and zeros, with 1 indicating column E values which already occur in these preceding cells.

 

2) IF(COUNTIF( F$1:F1, E$2:E$20)+ (E$2:E$20="")=0, E$2:E$20): this combines the 1) above with (E$2:E$20="") which returns TRUE for blank cells and this TRUE becomes 1 when used in calculation. As this is copied down, it returns an array of 1s and zeros, where 1 indicates column E values which already occur in preceding cells or for blank cells. The aim is to match with zero values and return non-blank column E cells which have not already appeared in preceding cells of column F - {111;333; 555;777; 333;111; 333;FALSE; 66; FALSE;...}.

 

3) SMALL(IF(COUNTIF( F$1:F1, E$2:E$20)+ (E$2:E$20="")=0, E$2:E$20), 1): Using the SMALL function with column E values returned in 2) above will return the SMALLEST column E value which does not occur in the preceding cells of column F. IFERROR function is used to return blank cells after all column E values have been accounted for once.

Column B: Cell B2 formula uses INDEX, MATCH, SMALL & COUNTIF functions and is entered as an Array formula (Ctrl+Shift+Enter). It Retains Duplicates & Sorts column A values in Ascending order. However, column A can have either ONLY Text or ONLY Numbers. The formula does not refer previous cells in the same column B.

 

Column C: Cell C2 formula uses INDEX, MATCH, SMALL & COUNTIF functions and is entered as an Array formula (Ctrl+Shift+Enter). It Extracts Uniques & Sorts column A values in Ascending order. However, column A can have either ONLY Text or ONLY Numbers. This formula also refers to previous cells in the column - if cell C2 formula is in a different column, replace "C$1:C1" in the formula with that column (ex. if formula is in column D then update to "D$1:D1").

 

Column G: Cell G2 formula uses AGGREGATE & COUNTIF functions and is entered as an Non-Array / Normal formula. It Extracts Uniques & Sorts column E values in Ascending order. However, column A can have ONLY Numbers. This formula also refers to previous cells in the column - if cell G2 formula is in a different column, replace "G$1:G1" in the formula with that column (ex. if formula is in column D then update to "D$1:D1").

 

Column I: Cell C2 formula uses the SMALL function and is entered as an Non-Array / Normal formula. It Retains Duplicates & Sorts column E values in Ascending order. However, column E can have ONLY Numbers.
