Termius doesn’t allow importing data from a CSV file per se, but you can convert it to an ssh config file and then import it as ssh config.
To convert a CSV file, you need to ensure it's correctly formatted (see below).
A CSV file must accord with the following format:
It is a plain text file named source.txt
Each new line represents a new entry.
The file follows this pattern, and blank fields are ignored:
{Name},{Address},{Username}
Router,192.168.1.1,adminRaspberry pi,192.168.1.15,piHome media center,192.168.1.16Work,81.138.33.19
Use the following command to convert your CSV file to ssh config:
awk -F',' \'{print "Host " $1 "\n\tHostname " $2; if ($3) { print "\tUser " $3 } }' \< source.txt > ssh_config
Host RouterHostname 192.168.1.1User adminHost Raspberry piHostname 192.168.1.15User piHost Home media centerHostname 192.168.1.16Host WorkHostname 81.138.33.19
