Hello @maurovmorais
Welcome.
You can build a datatable with Build Datatable Activity and create as many columns as you can.
Then you can insert data directly into table from UI or if it is dynamic you can save them in variable and the use Add Datarow activity and add to datatable.
Once you do this you have datatable with desired data, you can you Excel application scope with write range activity or write range activity of workbook.
All the best
Thanks,
