I need a simple array formula that calculates the sum from $A$2 to the column in A:A in array formula the picture explains everything
try:
=ARRAYFORMULA({"Total"; IF(A2:A="",, SUMIF(ROW(A2:A), "<="&ROW(A2:A), A2:A))})
i found it ^_^
`=arrayformula(SI(A1:A="Number";"Total";SOMME.SI(LIGNE(A1:A);"<="&LIGNE(A1:A);A1:A)))`
