    What would be a revolution in excel is if we could have probability distributions in cells. Right now all spreadsheets are fairly deterministic and we think that tells us something about the real world. Having an ability to make cells distributions (and then all resultant cells would be distributions too) would represent the uncertainty in the world better (and expose lots of interesting things like distributions of tails)

      Guesstimate (https://getguesstimate.com) has been around for years. I assumed Excel and Google would incorporate its features quickly, but it never seems to have taken off.

      Features:

      - All cells are named (auto named if you don't set them)

      - Cells can have single values, many types of probability distribution, or sample data

      - Formulas also produce distributions as first class outputs, because calculation is a Monte Carlo sim

      - Each cell also has a pop-up box that invites you to explain your reasoning -- built in documentation

      It got so much right. Sample data particularly useful because you can build a probabilistic bottom-up forecast and then update it with real-world data.

      What would this look like? Whenever I need something like that, I just stick each parameter in its own cell and use functions from there.

      I would love an easier way to communicate to tech/math-illiterate CEOs that worst case, average case, and best case are different things, but must all be planned for.

      When I did Process Improvement we used MiniTab for this.

      I honestly was not a fan of that program and would have loved to be able to use Excel, but there are so many statistical things you just can't do in it.

    • westurner an hour ago

      Would those then be tensors?

      Matrices are Tensors but with the matrix product operator instead of the tensor product operator.

      Pandas supports MultiIndex DataFrames but the pandas docs recommend xarray for 3D and N-Dimensional data.

      xarray supports N-Dimensional data as for example NetCDF but not tensor arithmetic.

      xarray_jax: https://github.com/google-deepmind/xarray_jax :

      > This library solves that problem. It registers xarray data structures as custom JAX PyTrees. This allows JAX to seamlessly flatten xarray objects into their raw arrays for accelerated computation and then unflatten the results back into fully labeled xarray objects, preserving critical metadata like dimension names and coordinates.

      flatten and unflatten with datatypes is necessary for unrolling loops for performance.

      Which is the correct logic for probabilistic logic, for expressions with frequentist or symbolic distributions as values? Are quantum logic and quantum statistical mechanics the appropriate or useful tools for all probabilistic logic?

      dist_a1 <operator> dist_a2

      uncertainties does mean±dev in Python with numpy types.

      From https://news.ycombinator.com/item?id=41411280 :

      > W3C CSVW supports per-column schema. ( with URIs for datatypes )

      > Serialize a dict containing a value with uncertainties and/or Pint (or astropy.units) and complex values to JSON, then read it from JSON back to the same types. Handle datetimes, complex values, and categoricals

      IEEE-754 specifies NaN (null), ±0, three infinities (positive, negative, and unsigned), but IEEE-754 does not specify a representation for categoricals, datetimes (like ISO8601), or complex numbers.

      XSD (XML Schema Datatypes), which RDFS vocabularies often use to specify the rdfs:range of an rdfs:Property, does not specify how to specify abstract complex numbers; but OpenMath RDF, and QUDT (Quantities, Units, Dimensions, and Types) and OM Ontology all have a way to save complex numbers to disk, too.

    I was skeptical, but this looks genuinely useful. I can already think of some use-cases for this, e.g. a spreadsheet I was working on recently had a list of user, and then a comma-separated list of software apps they were using. It was a bit of a nightmare to parse, but the example in the article would definitely help with filtering the list.

    I didn’t really appreciate excel fully until I worked at a company that forbid software development and had implemented a whitelist policy for executables. VBA was blocked too.

    Excel on Windows was the only tool available, outside of offering sacrifices to the high priesthood of IT.

    It is a supremely elegant tool capable of deep data integration and extraordinary analysis, if you approach it with an engineer’s mindset.

    This was during the time when they started introducing lambda and related functions. Nowadays, Excel is even more of a superpower.

    Unfortunately, Excel on Mac is not nearly as good. It has all the features, but it’s missing a lot of the UI needed to use them effectively.

    • wildzzz 4 hours ago

      I've worked at places like they. They did have a self-service app store you could use to install things. It also had an approval system for anything that cost real money for a license. Excel was the bread and butter for many engineers for a long time to make functional tools. The great part of Excel is you could make little GUIs with the tables, not exactly QT, but you could have labels and textboxes. We regularly used a tool up until 2020 that was originally created in Excel 97.

      MATLAB was the runner up for our tools but the good part about Excel was that every PC had it whereas MATLAB wasn't and also needed network access for the license (or else your program/department had to buy a node license). Later, many people switched to python since not everyone loves MATLAB and it's more of a real software language (and it's free) than what's effectively a very expensive calculator.

      • coliveira 4 hours ago

        The same thing that works for databases also works for excel. You shard the data and run your analysis on the set of shards in excel. It's not elegant, but can solve many problems.

        You underestimate the task by multiple orders of magnitude. It would be a significant effort even to build it on libreoffice.

  • bnj 5 hours ago

    I’ve recently been experimenting with OnlyOffice as a non-excel alternative that can still support a broad formula set and I’ve been really pleasantly surprised. I want to be able to use an open source spreadsheet system and onlyoffice is surprisingly robust.

    • Xirdus 5 hours ago

      Are you familiar with LibreOffice? Are there any advantages that OnlyOffice has over other open source spreadsheets?

      • bnj 2 hours ago

        Sibling comment nailed my feeling on this: the UI of onlyoffice is modern and clean. To add on, it gives me a feeling of confidence that it can round-trip files back and forth from excel more reliably; a lot of people on my team also use excel and we need to exchange workbooks, so that was what prompted me to move on from LibreOffice when I lost confidence that files would be able to remain pretty stable going back and forth.

      • Grombobulous 3 hours ago

        I’m a very occasional and casual user of office programs. Mostly I don’t use them.

        What I like about OnlyOffice over LibreOffice is the UI. I like how it’s one program that can open all the documents rather than a collection of different programs as well. It feels clean, simple, and modern.

      Is that a contradiction? Adding list and arrays doesn't break backwards compatibility. In general, guaranteeing backwards compatibility doesn't prevent you from adding new features, and having both old quirks and new features is fairly common for any decently old software

          I guess “so nothing”. The model is fundamentally broken. Adding a third dimension to certain cells by giving them a new type (‘tuple’, ‘list’?) whilst also having multiple sheets that aren’t (really) addressable is a disaster for the semantics.

  • qubex 5 hours ago

    The way to do mathematics on computers is via a CAS such as Mathematica. This is misguided pornography. Unfortunately as such it shall do what its implementers intended: for a while embrace, and if not extend, embolden.

    And yes, I know Wolfram Language is proprietary too, and, yes, I know Stephen Wolfram is a massive tool, and yes, I know Mathematica licenses are expensive, and yes, I am aware of probably all the criticisms you can level my way and at it and then some in various permutations thereof, but heavens, at least it isn’t this dissolute disaster otherwise known as Excel, where “numbers have a place” but they don’t need to be numbers, and they don’t need to be in a place or have a place, but they break silently whilst you run your hedge fund.

    EDIT: As soon as I get my hands on this monstrosity I shall embark upon a voyage to define several lambdas within the same cell as a list, and then make other cells depend upon it, and their type too, to see how far I can push this thing until it breaks.

    Users might see it as a good thing to have yet another feature, but this sort of type-softness is why Excel is bad. In general having every feature is a bad thing, you need constraints to design things, to have idioms.

      Microsoft is actively harming the laypersons comprehension of their data with 'features' such as this.

          You packed a lot of things in here! Let me try to tease them apart.

          > But me pointing out all the infrastructure this will likely break, and how, is not?

          Of course it's fine. It's a question of how you do it. There were two problems with your comment: (1) it was snarky, which we're trying to avoid and which HN's guidelines ask you not do do; and (2) you didn't provide much information, so it came across as shallow. The combination of snarky and shallow is bad for the conversation we're hoping for.

          It sounds like you have experience in this domain. If so, you could write an interesting comment about your experience (e.g. with spreadsheets, VBA, how they control businesses) and how the current release will break things. If you did that by adding details from your personal experience (anecdotes are king!) and avoiding snark, that would be more than fine.

          Such comments, of course, take time to write. It's taken me 37 minutes and counting to write this one. (Edit: 45 minutes.) If you don't want to or don't have time, that's ok—just please refrain from snarky/shallow/indignant one-liners.

          > A quote from the Baghavad Gita on this being a bad thing, is fine

          It's common (and understandable) that when people see comment A going unmoderated while their own comment B is scolded by a mod, they feel singled out for unfair treatment. I've described this in the past as "it always feels like the mods are against you" (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...).

          But there's a dirt-simple explanation: we don't see everything. Not even close! There's far too much for us to see even 10% of what gets posted here. So when you see a post that ought to have been moderated but hasn't been, the likeliest reason is that we didn't see it. You can always help by flagging it or emailing us at hn@ycombinator.com.

          > Because fine, if that's what keeps getting your attention (this isn't the first time)

          What gets my attention are comments breaking the site guidelines. It's nothing personal! I didn't remember replying to you before, though once you mentioned it, I looked it up.

          It goes against every bone in my Aquarian body to regard myself as a policeman, but the analogy somewhat holds here. Say you get pulled over for speeding. It's easy to feel you're being singled out. What about all the cars that were just speeding past you? do they get a pass? But it's not personal. Policeperson is just sitting there doing their (no doubt rather boring) highway duty.

          > I'll try to Americanise the way I talk here

          I gather that you perceive HN's guidelines as somehow specifically American? I perceive them very differently. They are an attempt at figuring out how to manage a very large internet forum across national differences—and other differences—without degenerating into mutual clubbing (the caveman kind, not the dancing kind).

          None of the HN moderators is American. The site was created by an American, but one who was born in England and has been living there for the last decade, happily ensconced. It's all so much more complex than one's quick assumptions are able to process, and when you fire those at people, even across anonymous internet space, it can really sting.

      And something that isn't AI or an advertising opportunity…

      Though they have been slowly adding useful new features to Excel (auto- spill is one I occasionally find to be both a time saver and a mistake reducer) for a few years now, after a long time seemingly doing very little with it. While I'm all for things having a "done" state and after that not doing much with them so as to not break a good thing, there is plenty of room for little improvements like new functions (admittedly many of them likely a bit niche) in Excel, just as long as they don't break what already works at the same time.
