Droplet user-data with new lines

Hi there,

is there a simple way to add a bigger user-data file into the string?

We have quite a few linebreaks and it is cumbersome to add those. Is there a recommended online tool to convert smth like

#!/bin/bash

add-apt-repository -y ppa:ondrej/php
apt -y update
apt -y install nginx
apt -y install jq

into “#!/bin/bash \n add-apt-repository …”

The option to add a file link at whould be great too.

user_data

and

user_data_file
