It may not be immediately obvious that the string input argument for "ConvertFormula" in the "Application" property node refers to the lower right corner where the 2D input array should go in "RxCy" format where x is the absolute row index and y is the absolute column index (number not letter). Do not confuse the letters "R" and "C" with column letters because the "R" represents the word "row" and the "C" represents the word "column".
Likewise the string input argument for "Range" in the "Worksheet" property node refers to the upper left corner where the 2D input array should go in "Ax" format where A is the absolute column letter and x is the absolute row index.
