All spreadsheets used to run in your terminal, in the old days. You can still download one here and I wouldn't be surprised if it still works: https://winworldpc.com/product/quattro-pro/4x

Right? Visicalc wasn't using anything that a terminal didn't offer.
jnpnj•Apr 6, 2026
there are some videos about quattro in those days and i was sincerely surprised how featured and advanced it was
the ratio of space / cpu / capabilities (beside the network part) is something that reaches deep in my brain
Teapot is pretty great, it's too bad there is close to zero room for real innovation in the spreadsheet domain. For the most part if it's not spreadsheeting how prophet Dan Bricklin envisioned, people don't want it.

Actually... on that note I realized have never tried lotus improv.
The easy way to accomplish this is to just launch a NeXTstep box in your browser from https://infinitemac.org/
I don’t know if they have Improv pre-installed, but it will let you mount disk images from your computer.
(Personally I find the easy way too easy, so I have NeXT^WOpenSTEP installed on bare metal on a 5x86 box. But that’s me)

> Teapot is pretty great, it's too bad there is close to zero room for real innovation in the spreadsheet domain.
One issue is that this is hard to do while still retaining backwards compatibility. Lotus Improv basically gave you no other choice, something that Excel The Next Version can't do. And I doubt that we're getting a third MS app, no Multiplan -> Excel -> NewSpreadsheetThingProbablyCalledCopilotAnyway.
I know a lot of people that don't even use Excel's tables, introduced almost 20 years ago. But instead they painstakingly recreate most of its built-in features. It's just an easy shortcut away, and has plenty of GUI support hidden in the ribbon morass, but it's not the default state…

Oh man, I played with teapot once a long while ago, but couldn't figure out how to parse values from XDR files in $LANG, or export some given sheet into CSV or other format- which sadly put a stop to my experimentation. Super interesting otherwise, and wish it had more eyes.
Exactly. I immediately thought, “So, we’ve invented VisiCalc all over again.”
freedomben•Apr 6, 2026
TBF, VisiCalc is not open source, and this is relatively fresh start, so I don't think it's fair to compare this to a reinvention.
drob518•Apr 6, 2026
Isn’t that what reinvention means?
freedomben•Apr 6, 2026
I suppose that's fair, and I concede, though I think you can play with the definition enough to make anything spreadsheet (even GUIs and webapps) be "reinvention" of visicalc, so I think the term is actually pretty meaningless.
drob518•Apr 6, 2026
My point was, it's a spreadsheet in a term window. That's basically what VisiCalc was in the 80s.
freedomben•Apr 6, 2026
Appreciate the clarification, and sorry, I wasn't trying to be a pedantic pain in the ass :-)
jnpnj•Apr 6, 2026
pretty cool, most of the time I don't want to spin emacs org-table nor google sheets for a quick table

Visidata is a fast popular data tool in python https://www.visidata.org/ if you just want data entry.
If I may be permitted a small plug ...
Oleo is a GNU spreadsheet going back absolutely donkey years. I cloned the repo here: https://github.com/blippy/oleo and made minimalist fixes to get the thing to compile.
I wouldn't say that my project is particularly good, but it does have a number of features that I find useful. The next release will include Tcl bindings, so you can customise some of the workings of the app. There's also a module available where you can go to town programmatically.
It opens up a world of possibilities, including stuff like pivot tables.
package require oleo
load-oleo mysheet.oleo
set ws [toMat]
set subset [subRows $ws [mand [mstreq 2 foo] [mstreq 3 bar]]
It has what I think is a nice little query language, too. In the last line I select the rows from the spreadsheet sheet column 2 is equal to foo and column 3 is equal to bar.
I'm kinda dog-fooding it at the moment to put in place features that I need. It doesn't have the full equivalence of SQL-equivalent though.
izhak•Apr 6, 2026
vd (visidata) is amazing. The only tool that really works for me with millions of rows csv's
Thanks for showing this. What would you say the differences between the classic version of oleo and your neoleo version?
blippage•Apr 6, 2026
Oleo is C, circa 50k of C code, Neo(-leo) is around 5k of C++ code. A 10th of the size, but not necessarily any less powerful. Oleo has some memory leaks in places, whereas Neo has no (known) leaks.
Oleo uses lex and yacc, whereas Neo has a hand-parser.
Oleo is in the style of emacs bindings, whereas Neo is more vim-like, but without the modality.
I think the Neo code is better-structured and more readable (but I would say that, wouldn't I? - although it is far from perfect). C++ generally makes code more readable and obvious, without all that pointer arithmetic.
The internals of Oleo are more complicated. It uses byte-code for cells, for example. Neo stores a parse tree for a cell. So you can see that a lot of programming effort is saved right there.
In terms of speed, I suspect that the original Oleo is faster, although it's difficult to benchmark.
Neo is also heading towards being a library that you can compile in with other C++ code. Plus there's an interface to Tcl, which Oleo never had. So you get a lot of extensibility there which Oleo doesn't have.
I also think Neo is more generally accessible. It's got something in the way of a menu (still early stages), which helps. Neo is just generally less fiddly with editing cells, IMO. The mouse works, too.
Oleo does have an interface using Motif. Very early-90s. There's even an interface to GTk, although I don't think that works properly. I decided to abandon all that and just stick to an ncurses interface. After all, if you want a fancy interface, there are proper options these days like LibreCalc, Caliigra and Gnumeric.
blippage•Apr 6, 2026
To add to the cool things you can do with Neoleo, I wrote a little TCL extension that loads current processes into the spreadsheet. I added custom bindings so that you could search for processes, go to its parent, and kill processes.
I'm also half-way to adding a little calendar extension, too.

Whoah, you weren't kidding!
blippage•Apr 6, 2026
Yes, I'm partial to a bit of retro. It does back to around 1991, IIRC. I don't think it had a curses interface in those days.
And check this: version 1.2.2 is available on Aminet, for the Amiga. How's that for a blast from the past?
m-hodges•Apr 6, 2026
VisiData is superb. It can work with website tabular data too; great for scraping.¹
Semi-related: I always wished there was something like the unholy combination of a spreadsheet and notebook rolled into one. I picture it notebook-like at the top level, then each cell is a widget that the host language can reference parts of in other cells (probably with a variable (eg: something like mathematicas `Out[_]`) or a built in construct (like the `$ABC123` forms in spreadsheet formulas)). A notebook interface would also be good (I think) as a straight up terminal as well, as you (I) typically want to run commands in an order like in a notebook
BirAdam•Apr 6, 2026
Some time ago, I remember Microsoft having made a video for a "courier tablet" that was essentially an electronic notebook. Either side of the spine was, by default, just plain "paper" that could be drawn or written on. It had some kind of intelligence to recognize stuff, so if you started drawing out a grid it had basic capabilities that could be attached to that grid, like spreadsheets.
At least, these are things I think I remember. It's not quite what you're imagining, but it was cool and along the same lines.
chrisweekly•Apr 6, 2026
I think that combination exists using Obsidian.md, via built-in "Bases", or dataview / datacore plugins.
jasaldivara•Apr 6, 2026
Do you know TreeSheets[1]? It kind of sounds similar to your notebook idea.
If I’m remembering correctly, I had bought a Borland Turbo C++ compiler circa 1994 (for DOS) that came with a demo sheets application you could build and run.
Does anyone remember this, I can’t find it now.

Anybody ever bound a Google sheets to a CSV and provided a TUI for that? I expect it would be slow.
Two-Way synchronizing of a text file version of Google sheets is another way to think of it. Aside from that, there would also be the need to implement the spreadsheets user interface of highlighting and all that stuff, in the TUI side.
To really be useful (to me at least and a handful of others I've talked to) it has to have xlsx support or at least open document format. If you're not sharing it with anyone then csv-only is fine, but still very limited. This project is early days though so shouldn't be judged for a while, but I would heavily suggest not overlooking compatiblity support even though it's a nasty boondoggle.

this is probably the thing being replaced in that excel elevator demo commerical from microsoft in the 90s
nickjj•Apr 6, 2026
The functionality I miss from a GUI spreadsheet is this "simple" case:
I have a spreadsheet with 186 rows and want to select a specific cell's value from rows 6 and 127 and immediately know the sum if it happens to be 2 digits. Most of the time it's from the same column but not always.
With a GUI, this is really easy. CTRL + left click each cell and get the answer in a second. Throw SHIFT into the mix if you want a range of cells.
SoftTalker•Apr 6, 2026
To be clear, this is a TUI spreadsheet called "sheets" not a TUI interface to Google Sheets spreadsheets. Unless I completely missed something.

I found a copy of the win3.1 version here. https://archive.org/details/lotus-improv-2.0-for-windows-2.0...
But my plan is to go for the full nerd experiance and see if I can get the nextstep version to work. https://winworldpc.com/download/7c521434-e280-a0e2-82ac-11c3...
Which will require a NeXT machine emulator https://previous.nextcommunity.net/
Wish me luck.
