Excel Formula : Convert data from long to wide format

Suppose you have data that is stored in long format in excel. You want to reshape it to wide format.

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 {}.

Column A does not necessarily to be in numeric format. Similarly, Column B can take both numeric or character values.

Step II : Reshape data from long to wide format

Type the following formula in cell E2

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

The data in Column A must be numbers?
I tried text data and got wrong results

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),"")
