I've not seen any requests for a Smartsheet's equivalent to Excel's OFFSET() function. For how universal the INDEX(MATCH()) solution seems to be, it strikes me as a notable oversight that there isn't any function to achieve a similar effect for selecting a range of cells offset by a column index value. It would greatly simplify a few of my solutions to have a reference of a single 2-dimensional array where I could toggle the column instead of a new reference for every column.
