Hey ITFromValor,
In order to have no extra columns or rows you will need to play around with the spacing around the fields and also the main detail body.
Here I used a table to list my data but note the space around each row. If you leave any white space in the detail space then it will create new rows in Excel as shown.
If you use separate labels then you will have to make sure they are large enough to fit the text so that it doesn't word-wrap onto a new row and have no space beside the neighbouring label so that it doesn't create a new column in Excel. Thats we recommend to use a table so that the spacing is more automatic.
What you want in the end should look like the images below which will export to excel properly.
For seperate labels:
