To answer your question, much of the information is text, and I'm trying to cram a lot of it in. The "Description" column in particular eats up a lot of column width, and I'm trying to keep the rows one line tall. Some items have subtle differences, and two word descriptions don't cut it.
OTOH, you are correct about the lining up of numbers, such as monetary values. Monospacing applies to my location coding as well, as it follows a set format of 7 characters. I ended up using both std. zeros and dotted zeros there in different positions in the code, so I was using Source Code Pro for the location codes, but have switched to DejaVu Sans Mono. (It's not a compact / narrow font, but, the column is only 7 characters wide, anyway.
Only 2 columns are numerical ($$) fields, so, at least for now those are getting Arial Narrow (Bold).
There is also a column titled "Mod?". That refers to alterations, usually by yours truly. I threw in the towel there: The fields get either a "N" for "None", or a "Y####" as an alphanumeric code ("Yes" and numbers) to look up elsewhere, or maybe later on in an extension of the spreadsheet. (Basically another spreadsheet at the end of the spreadsheet, but, I may decide that's too cumbersome.)
I'll look up those fonts you mentioned, as I don't "know" them, except Courier, of course. I might like one of them! I'd look at any other "narrow" monospaced font with excellent legibility, too. (My eyes aren't quite what they once were, even with my new glasses.)
Thanks again!
Well, if you want a narrow font for text, either Arial Narrow or Narrow Helvetica are common “go to” choices. They used to be included in Windows, but sometimes is not installed by default. It starts being hard to read below 9 pt size, though. I find Letter Goth 12 (which has to be hunted down and downloaded) is not “beautiful, but is quite readable.
