Well, get the row to write to using Get first free column/row from Excel worksheet. I assume this is quite clear?
Then use a loop when writing your data. Loop through the values/columns in your data and keep incrementing a variable for a column index. Then use the column index in Write to Excel worksheet to specify the column to write to.
The specific way in which to build the loop depends on the data you want to write. If the above is not clear/detailed enough, please provide more context as to what sort of data it is, and we can then help you out with a more specific explanation.
