Zenity checklist from file

I created a checklist and I want to insert data from a file in a specific order. The data comes from a terminal command in my bash script: data=$(lsblk -o name,size,model --nodeps >> /data.txt This is the content of the file: How can I match the checklist with the content of the .txt file? I tried something like cat data.txt | tr "something" but it didn't work according to my needs. This is the output I get, when combined: Thank you for your time!!
