People are all talking about how it's useful for quick stuff with datasets, but it goes far beyond that. It's useful for quick anything you might want a small database for. Imagination is the limit.

For example, if any of you play D&D online, you might be familiar with dndbeyond's character sheets. They're a fantastic way to onboard new players who might not have the inclination to spend hours with the rule books before they even start playing. It does all the calculations for you and gives you some buttons like "roll athletics" and doesn't let you add more spells than your character can have with their stats.

I recently persuaded some friends to give FATE a try and built analogous push-button character sheets with google sheets [0]. It was quick and simple. With conditional formatting, you highlight bad states (rules say you can't have more of X than Y!). With the script editor, you can add full on buttons for dice rolls and other state changes with whatever logic you want (anything you can code up!). Checkboxes are obvious but super useful. And the transparency of the calculations is helpful for teaching people the system (this stat is "min(A4, B1+C5)").

Without google sheets, it would be a serious endeavor to build a stateful, database backed, live collaborative GUI that can be added to and customized on the fly by my users. With google sheets, it was a quick fun afternoon hack. Excel/google sheets is an amazing piece of technology.

We started a company with the core premise that spreadsheets will never die [0]. Spreadsheets are so good at the most casual data viewing and exploring tasks to creating complex financial models. They are also the de-facto choice when you have data (not big data) from multiple sources that you need to "join". We tend to underestimate the beauty of this tool which can be used productively at all points of the skill spectrum. Everyone feels at ease in the familiar territory of a spreadsheet, which is what makes it ubiquitous and basically impossible to kill.

If spreadsheets were two-way connected with your core systems like SaaS tools, DBs, Slack, etc then you could represent serious business logic and actions without being a programmer. It is the best platform to build a "no code" tool for non-programmers.

That's awesome, Navneet! I have heard from big hedge fund managers, and seen first hand working at "cutting edge" 401K fintech companies that spreadsheets are the backoffice workhorse in many many companies doing serious business and handling serious data.

I am curious about one aspect though: Debugging spreadsheets is seriously hard. How do you help customers verify their spreadsheet has the right things they are looking for, avoiding regressions due to a random change by some inexperienced person, etc.?

Also, at what point do you see companies move from spreadsheets to simply hiring developers to do what they want? It seems like beyond a point, spreadsheets can get in the way, and the company has enough resources to hire a team to build custom internal tools.

Good luck with Coefficient!

Spreadsheets are everywhere. Heck our local power company uses a complex spreadsheet for load prediction. It includes holidays, football events, historic weather and weather predictions. Saves them a bundle.

Navneet, as someone looking to buy a solution such as yours, the website isn't answering my #1 question:

> Does coefficient.io work with MY system?

What databases can you connect to?

I'm running a game of D&D and needed an accessible character sheet that works from a phone with good support for pinch-to-zoom.

Tried fillable PDFs and a bunch of online stuff. None of it worked well. The spreadsheet fields' font sizes were all weird, and even if you manually correct them it would reset on every edit. There were some promising web-based options described as "responsive character sheet", but they tended to fall apart at large text sizes.

Best option? A spreadsheet from Knights of The Braille: https://knightsofthebraille.com/59-2/

Instead of trying to shove an 8.5x11 paper layout into a phone, it just groups stuff into tabs that make more sense anyway. And if you were completely blind I bet it's still easy to navigate with VoiceOver.

We're using Numbers because it's what we both have, but I think Excel should work similarly.

If anyone's reading this from the Google Docs team, please take another look at Sheets' pinch-to-zoom behavior. That was the first place I ended up when I went looking for character sheet spreadsheets online, and it was the first one I ruled out because of how shitty the experience was on mobile.

Past edit window, but if not obvious from context "spreadsheet fields" should be "PDF fields"

I think every IT professional should at some point work for a non-IT company (where hopefully they are tech-savvy enough to be using spreadsheets). It's amazing to see what people will use it for (answer: everything).

[Waterluvian]

Absolutely.

My last five uses of excel are widely variant in theme:

- validate my taxes make sense

- track Bloodborne platinum trophy progress

- collab with wife on Christmas gift planning

- estimate lumber purchase for project

- collab with coworkers to explore ota data culling options.

[geoduck14]

How much did you spend on lumber?

I find with excel it takes just as much time to set up a spreadsheet to do what I want as it takes for me to do the same in R, usually a lot more time with Excel. Both pieces of software have learning curves, just to me R is the better tool for the job for working with tabular data. Excel forces you to hardcode your fomulas and ultimately adds a lot of cruft and time wasted, compared to R which is much more modular. That "min(A4, B1+C5)" is liable to break if your spreadsheet changes. R functions on the other hand are pretty well documented, and you could do anything you want in R after following a tutorial for a couple hours. Instead of having to hard code a position, you can refer to it relatively or by some unique identifier, so your calculations still work no matter how your underlying spreadsheet changes or is shuffled around (and familiar formulae like sum and min and max are there by the same names). It's way easier to do statistical tests and plot data consistently in R as well. Oh, and you can export to .csv or .xlsx from R if you'd like of course.

1. You know how to program.

2. How does the UX for your R solution to the "DND Character Generation" problem compare to the screenshot from grandparent comment, for users not familiar with either R or Google Sheets?

[jjnoakes]

> That "min(A4, B1+C5)" is liable to break if your spreadsheet changes.

I don't usually have that problem. Inserting or deleting rows or columns around the cells doesn't break these formulas. Only changing what type of information a cell contains would. Does this happen often for you?

[gamblor956]

Cell references in Excel are not hard-coded; they are automatically updated if you modify the spreadsheet by deleting or inserting other cells, and unless you use the $ before the col or row they automatically increment/adjust when pasted into another cell.

And you can just name a cell or range if you want to use a variable name to refer to some data in a pivot table or formula.

[CJefferson]

At no point do you talk about UI here -- for a character sheet (or most simple things), I want to control layout to some degree, let users edit some numbers, and see others automatically update. Obviously I could have a file full of constants and a bunch of print statements at the end, but is there anything nicer / more dynamic?

> I find with excel it takes just as much time to set up a spreadsheet to do what I want as it takes for me to do the same in R, usually a lot more time with Excel.

I mean, this is I reach for Pandas over Excel, but most people would be infinitely more comfortable with spreadsheets than specialized tools. Spreadsheets also happen to be useful enough for almost everybody.

Thanks, I'm definitely going to check out those sheets. I haven't d&d'd in a while and was thinking about joing up to a group at my local comics shop.
