Editing csv by hand is something I’ve seen a lot for internal-only software where every user is a super-power user who need to move small but bulk amounts of data and sometimes make small edits for formatting. Easiest example is geo, I need 20 states listed as US-CO, US-CA, etc but one tool exported as US CO.
