Extract Data In Rows And Transpose To Columns?

I am struggling with an Excel Database, to make it "cleaner". Here is my problem. My database looks something like that:

Column A Column B Column C ... Column H
ID Age Date of Birth ... Language
00001 14 01/01/2000 ... English
00001 14 01/01/2000 ... French
00002 14 01/01/2000 ... English
00003 14 01/01/2000 ... French
00003 14 01/01/2000 ... German
00001 14 01/01/2000 ... Spanish

Basically, Columns B & C will never change for the same ID, but columns G, H and others contain data that is different from one row to the other. What i wwould like to do is having unique values in Rows, with Languages displayed in Columns. The database would look like this:

Column A Column B Column C ... Column H Column I Column J
ID Age Date of Birth ... Language 1 Language 2 Language 3
00001 14 01/01/2000 ... English French Spanish
00002 14 01/01/2000 ... English
00003 14 01/01/2000 ... French German

The challenge is that I would need this to be done with formulas only, not using any kind of code. Deleting duplicates manually after "cleaning" the database should'nt be a problem. I tried a formula found on this forum, but i couldn't manage to make it work. The formula looked like this:

{=IFERROR(INDEX($C$4:$C$8;SMALL(IF(FREQUENCY(MATCH($C$4:$C$8;$C$4:$C$8;0);MATCH($C$4:$C$8;$C$4:$C$8;0));ROW($C$4:$C$8)-ROW($C$4)+1);ROWS(C$16:C17)));"")}
