How can one jump to a specific line in Numbers?
If you have trouble opening the file and you just want to see that line try the following in Terminal. If you have never used Terminal before, note that you must navigate to the directory where the file is first, the easiest is to copy that file to your Desktop and run the following command in Terminal to navigate to your desktop folder:

cd ~/Desktop


Then run this command:

head -4223860 mybigfile.csv|tail -1 &gt; export.csv


where "mybigfile.csv" would be your filename and export.csv is the name of the exported file. You can also display the line in terminal without saving to any file with:

head -4223860 mybigfile.csv|tail -1
