It is also the original purpose of TAB: the tabulation key, used to delimit tabular data. I also like that TSV files are both readable in plain text and easy to manipulate directly in editors like Vim and Emacs via rectangle operations or macros. That’s often a quick way to e.g. delete or transpose columns, or even do simple math operations on columns, without needing to go via Pandas, Excel, etc.
