You get a lot of variety from a SoloCutz spreadsheet (compared to generic table-driven solo oracles), while at the same time you can be more focused on the tone and genre you're seeking.
One advantage of the SoloCutz approach over certain other solo tools is that you can choose the title that best fits your genre and tone. In some other solo tools, you're rolling on generic tables that are supposed to work regardless of the tone or genre of your campaign. Fairy tales for kids? Science fiction for adults? Generic oracles would have you use the same word tables for both.
Another advantage is the sheer number of possible results. A generic oracle might use d100 tables or something smaller. Statistically, if you're rolling d100, you're likely to start repeating previous rolls by about the 12th roll. A d20 table is likely to start repeating after 6 rolls. That's not much variety. In contrast, Part 1 of Le Morte d'Arthur has 20,539 entries, and Part 2 has 24,028. For a table of 20,539 entries, repetition doesn't become likely until the 169th result.
The spreadsheet gives you 20 random excerpts from the text. Each excerpt is several words long, typically not a complete sentence. The spreadsheet offers you a way to flag some results as keepers so you can you reroll the rest. Once you're satisfied, you could then copy the results elsewhere.
My preferred usage is to pose a concrete question, and then I use a result that answers my question or that implies or inspires an answer. If I ask "Where does this scene take place," a result like "he put Sir Tristram in prison, and" suggests that the scene takes place in a prison. A result like "talking together, therein came twelve" doesn't name a location, but it implies a location where people would be talking together, so I could make the location a noble's hall, during a meal. If I ask "What is Sir Leodorak doing," the result "he put Sir Tristram in prison, and" could suggest that Leodorak is either imprisoning someone or being imprisoned himself -- whichever seems more likely or more interesting in context. The result "talking together, therein came twelve" could suggest that he's in conversation, or that he's arriving as part of a group (of twelve, maybe).
A nice touch is that Tangent Zero trimmed the fat from the original -- no extraneous stuff like front matter, end matter, or chapter headings. All results are from the body of the work.
The spreadsheets include a few common dice results for when you need a numeric answer or when you have a yes/no-style question. For my part, I don't need these spreadsheets to be my dice roller, but the dice results don't inhibit my use of the tool.
You need no more than basic spreadsheet skills to use the spreadsheet, such as triggering a recalculation or copying and pasting.
