You said adding a k was fine. You can do a custom number format in Google Sheets that just adds a `k` to the end of any number. Might look weird if you're dealing with values in the millions or more (like 3,230k).

Edit2: Actually it kind of blows if you need numbers not rounded to thousands. Entering 3.2 would look like 3,000.
