The data is shown in the image below : -

Reshape data from long to wide format

Step I : To pull unique values from Column A

Type the following formula in cell D2
=IFERROR(INDEX($A$2:$A$100, MATCH(0,COUNTIF($D1:D$1, $A$2:$A$100), 0)),"")
Press CTRL + SHIFT + ENTER to confirm this formula as it's an array formula. If this formula is entered correctly, you would see the formula inside the curly brackets {}.

Step II : Reshape data from long to wide format

Type the following formula in cell E2

=IF(COLUMN(A1) <=COUNTIF($A$2:$A$100,"="&$D2),OFFSET(INDIRECT("$B"& COUNTIF($A$2:$A$100,"<="&$D1)+2),COLUMN(A1)-1,0),"")

Paste the formula to the right and down so that transformation happens correctly. You can use CTRL + R shortcut key to paste the formula to the right and CTRL + D shortcut key to paste the formula down.

  2. The second COUNTIF should be a MATCH() instead. It should be:

    =IF(COLUMN(A1) <=COUNTIF($A$1:$A$100,"="&$D2),OFFSET(INDIRECT("$B"& MATCH($D2,$A$1:$A$100,0)),COLUMN(A1)-1,0),"")
