Flow: Adding rows to spread sheets from "Get customer data" in proper formated lines

Update:

Now I got it to work at least in some way. The customers data is still not in one line for each customer. Instead now all the first names are in one cell, the last names in one cell, the mail adress and the tags. So it fills only 4 cells in all instead of x lines with 4 cell, each line for one customer.

Here the row content I am now using:

{% for getCustomerData_item in getCustomerData %}
{{getCustomerData_item.firstName}}
{% endfor %},
{% for getCustomerData_item in getCustomerData %}
{{getCustomerData_item.lastName}}
{% endfor %},
{% for getCustomerData_item in getCustomerData %}
{{getCustomerData_item.email}}
{% endfor %},
{% for getCustomerData_item in getCustomerData %}
{% for tags_item in getCustomerData_item.tags %}
{{tags_item}}
{% endfor %}
{% endfor %}

So basicly, although it changed, I am still searching for a way to skip to the next row after each customers data …

Kindest regards!
