Lotus 123 he wielded for engineering calculations and thus Lotus 123 was his weapon for business letters. No spell check of course. No line breaks either. Such was my editorial lot.

What I'm trying to say is: it doesn't matter what the tool is. If the process / outcome are worth it, then starting to write is much more valuable than the exact tool (that you choose to get the cool kids nodding their heads in agreement). Productivity is cool.
Someone below mentions that Excel is probably an "upgrade" from a typewriter. What. Sure, Excel has undo and arbitrary text insertion, but so does Photoshop. Ask yourself if Photoshop would be an upgrade from a typewriter just because it's newer. At some point, the impedance mismatch wrt the actual task it was conceived for is so great that it will dominate any equation related to suitability for a particular purpose. So even the most recent version of Excel is still more ill-suited for writing than things actually made for writing, like typewriters and old word processors.

Trying to invent a hierarchy for unorganized thoughts is certainly a waste of effort.
Then try to surface the topology using whatever tools you like.
You don't have to publish. It's just writing, it's for you first and foremost. Over the years revisit, refine, and expand on your thoughts. Write articles over the course of 10 years. See how clever or ignorant you were 5 years ago. Allow yourself to laugh at your own jokes or to delete some posts in embarrassment. Let your mind be changed as it's meant to, safe from judgment. Some day you may feel wise enough and ready to share some selected pieces that have remained constant all throughout.
