B = XLSCOL(A) takes input A, and converts to corresponding output B. The input may be a number, a string, an array or matrix, an Excel range, a cell, or a combination of each within a cell, including nested cells and arrays.

The output maintains the shape of the input and attempts to "flatten" the cell to remove nesting.

Numbers and symbols within strings or Excel ranges are ignored.

xlscol(256) % returns 'IV'
xlscol('IV') % returns 256
xlscol('A1:IV65536') % returns [1 256]

I adapted the modular math from Mike Sheppard's program ExcelCol, to properly handle the conversion from column number to strings. His program is at
