Hi - as advised Excel needs a license but if it is simple reading and writing of data to a file then perhaps a CSV format will work. See the Utility - File handling and Utility - String to create a text csv and write to file. No MS license required. CSV are also readable from Excel for those users that need to read the data and have an Excel license.
