You need to go on github and do a search for xlsx. There's a lot of ready golang library for working with xlsx.
For example, https://github.com/tealeg/xlsx
Or even https://github.com/tealeg/csv2xlsx A simple program to convert CSV files into XLSX files.

In General, xlsx is just a format - basically an xml Packed in a zip and zero to do.
