Matrices are made up of an array of columns and rows where the vertical arrays are known as columns. Columns exist in real life too. For example, people in a vertical line or queue are arranged in a column. Row Definition Rows describe an order where people, things, or data are ...
The second formula that converts a column into 2D range works with the same logic. The difference is that you use the ROW + COLUMN combination to figure out therow_numargument for INDEX. Thecol_numparameter is not needed in this case since there is just one column in the source array. ...
You create 2 helper formulas (a column match and a row match. Then your INDEX formula just brings back the value from the cell with those coordinates. This formula then still works correctly even if your Pivot table columns are re-ordered or new one is added / disappears or if a new co...
