How do I insert a space between each letter? i.e. ABC becomes A B C

To have more space between each character, just go to the Text Inspector and use the Character spacing slide to add as much space between each character. If you already have a document, just highlight the whole thing and use the slide to adjust the gap/space.

I am familiar with the spacing slider

1. Spacing slider (technically called tracking in English, Lauflänge in German) can be freely used without affecting searching afterwards.

2. Spacing by inserting the character SPACE (technically this is what pressing the spacebar key does) constricts the audience to insert the character SPACE, too.

In general, if other people will work with the softcopy whether in plain text, in HTML page markups or in PDF page descriptions, inserting tracking is advisable whereas inserting SPACE is not advisable.

what if I wanted to add an actual space (space key) in between the letters

Could you indicate what the purpose of this is? Are you perhaps trying to create the double-width Latin characters used in Chinese（ＡＢＣ）?

I need to turn everything into a graph where each Letter, Number and Character is in its own column.

In this context, set up Tabulators where each and every one is defined as centered. This way, the variable set widths of the sorts (letters, glyphs) will align vertically.

Note that if you are working with Apple Advanced Typography or Microsoft OpenType font files, your font file may have a special subset of monospaced figure (number) sorts termed Tabular.

The monospaced figure (number) sorts may either stand on the baseline to align with UPPER CASE or have strokes ascending above and descending below the baseline to align with lower case.

Your font file may also have other special subsets of figure (number) sorts that are proportionately spaced. You should play with these subsets to see which figures will work well for you.

In typography (as in photography and lithography) what looks right is rights. Intelligent fonts for composition and intelligent profiles for separation are there to help you with the visuals.

Then if that is what you want, you are in for a long and arduous task.

I wish I knew of a way to do what you want, but I don't.

Find and replace does allow you putting a space before or after, or both, a letter. It is still some work to get it done as you probably have to do this for each letter in the alphabet!
