    Convert upper triangular half of matrix to column

    Hi. I'm working with a 327x327 matrix. I need to convert the upper part of the matrix into a column, labeled with appropriate row and column origin; I don't need the diagonals or the lower triangular. Does anyone have an Excel formula that can do this?

    Hi gmperry and welcome to the forum,

    See the attached that uses a formula of Indirect and Address with the Row and Column numbers being built for you in columns A and B. Does this do what you need?
