The weirdest spreadsheet you've ever made?

  • 1.  The weirdest spreadsheet you've ever made?

    Posted 01-29-2026 02:07 PM

    A friend recently told me he might need to start a list of... all the dead people he knows.
    Dark? Yes.
    Organized? Also yes.

    That got me thinking about some of the more fun spreadsheets I've made over the years.

    One of my personal favorites:
    I ranked the food I ordered through the Too Good To Go food waste app. (If you don't use this app yet, consider checking it out.)

    Since you never really know what you're going to get, I started tracking the following stats from each food place I'd use the app at:

    • What I paid

    • What I received

    • My perceived value of the haul

    • Whether I'd order from that place again

    After a few orders, I basically had a data-driven leaderboard of surprise leftovers.

    What's the weirdest, funniest, or most unexpected spreadsheet you've ever made?

    Every year, I have an ice fishing spreadsheet that gets reused to estimate ice thickness based on a two-week lookahead weather forecast.  

    Starting around Thanksgiving (and earlier, if the evidence supports it), there's a high-low forecast entry for weather, and columns for notes on the local lakes (they freeze in a sequential order).  Once a lake is noted as partially frozen over, the forecast is used to estimate when there will be walkable ice (4" thick), ATV-supporting ice (6-8" thick), or truck-supporting ice (12"+).  Once a week, the update includes a review of the actual high-low temperatures from the week prior and any updates to the future forecast.  

    Haven't gone through the ice yet from it.  

    Some years, I've been out fishing as soon as November 10, and one year had only 10 days of walkable ice all winter.

    Like William, I once created a spreadsheet to rank my favorite music (I did albums rather than songs). I created 7 ranking categories and scored all of the albums on my short list from 1 - 10 in each category. I only populated one category per day and hid all of the other categories to try to eliminate any bias. It gave me the wrong answer, but it was a fun exercise, anyway!

    I also once created a spreadsheet to track the accuracy of weather forecasting where I lived at the time. It turned out that over the course of about half a year, the forecasted temperature 10 days out was, on the average, more accurate that the forecasted temperature 8 or 9 days out.

    I also use Excel every year at Thanksgiving (more as a graphical interface than a spreadsheet) to keep track of when every dish needs to go into or out of the oven or on the stove. Dinner has only been late once in the last 5 years!

    I love this idea too. Going by albums makes ranking so much more difficult than going by song alone. Feel free to share some of the best albums like William did below! I'm curious as to how you ended up with a "wrong" answer too. Did you know deep down that your favorite album according to statistics was not in fact your favorite album?

    Thats awesome. I love a good sport spreadsheet. I've been meaning to start a spreadsheet for surfing that compares predicted "good" days against actual reality at a given beach that day. Thank you for sharing!

    Thanks for that, Chris. Took me back to 1960s in Phoenix, where a local radio station began every day with a "Surf Report" for Arizona. We never had any.

    Wonderful question, Chris. May I offer two?

    My first (pre-software) was hand-written on a columnar pad listing the pros and cons of marrying my fiancé soon or after college. Ranking weighted priorities provided the push we needed to marry soon. Sixty years later, we suspect the spreadsheet gave us good advice.

    A more recent attempt listed my favorite tunes/songs. Striving for a top 10, the spreadsheet quickly grew to 268 items. Sigh. Considering only candidates for a top 10 provided a top 58. Ranked choice voting narrowed it to these 22:

    Time and Tide Basia
    8 o'Clock Rock Bill Haley & Comets
    Aint No Sunshine When She's Gone Bill Withers
    Dancing with Myself Billy Idol
    Love will keep us together Captain and Tennile
    Roll Over Bethoven Chuck Berry
    Smoke on the water Deep Purple

    Nutbush Ike & Tina Turner
    White Rabbit Jefferson Airplane
    Do You Wanna Touch Joan Jett
    Rhapsody in Blue Leonard Bernstein and Columbia
    Blue Bayou Linda Ronstadt
    Let 'em In Paul McCartney

    Not a spreadsheet of mine but one my CE father made. He was working for a railroad that consistently had discussions with locals and environmental groups about vegetation removal efforts. One day reading our local paper, he read an article about goats being used to clear vegetation. It has enough data points in the article about herd size, duration of vegetation removal, and area completed that he could try to estimate the number of "goat days" to clear the entire railroad RoW. Given the cold climate where we lived, there were not enough "goat days" to make it a viable option for them and he had the numbers to back it up. 

    Still makes me laugh.

    One of the weirdest (but surprisingly useful) spreadsheets I've made was a long-term repair and maintenance cost tracker for industrial and electrical equipment.

    It looked simple at first, but over time it turned into a living document where I tracked repair frequency, cost deviations, failure patterns, and how "temporary fixes" quietly turned into permanent solutions.

    The funny part? The spreadsheet eventually started predicting which equipment would fail next better than some official schedules.

    Not weird on the surface - but a little unsettling when Excel starts behaving like a crystal ball 😄

    You all seem to make incredibly advanced works.  
    but I have to give myself some confidence as being a solopreneur since grade school.  My parents were divided from each other.
    I conceived of a few principles of food economics, and was restricted in a target to find a workplace, such as a student frequenting a coffee shop to work, while being cordial and meeting others.  My incentive was vegetarianism vs. any meat, generally only chicken as diet, and seeing that there was a relationship to mileage, but also to the types of thoughts I could emit to others and some aberrations depending on how many people were in proximity.  This was influenced by having visited East Asia India and arriving at a state to know my parents had lived in the Indus Valley, and visited other countries.  You see I was from a bicycle town in N. California…. The experiment has been realizing there is a balance of our intellects with the foods we eat , the proximity we are to others (or the distance) and travel heeding energy consumption for travel.  The spreadsheet included all my consumption receipts, fuel to mileage records with maps directions mileage.

    ; and generally included the intellectual work scope that I was able to complete.  
    How much violence?  How much peacefulness?

    How much consumption?  How far?

    Quality of work ?  A bean counter to conceptualize the differences between countries with fewer people vs countries that have very high population Density, to begin to understand why religion/social order is present as it is in ea. Country.

    That's an amazing example, Refugio. It took a lot of effort to figure out those parameters and how to combine them.

    Thanks for sharing it.

    Well it was all unintended. Typically the framework is already there.
    There is a setup though not any final conclusion except a theory based on the experience & a concept framework... Then finding some intended theorists with similar postulations that could possibly fit the dataset.

     I really enjoyed reading these creative examples of unconventional spreadsheet use.  
     For me, the "weirdest" (and perhaps smartest) spreadsheet I built dates back to 2015, when I tried to address a limitation in ETABS 2013. At that time, the software provided design results but did not test whether reinforcement distribution was practical or compliant with section dimensions.  
    I developed a file that does not rely on a single formula, but rather on a dynamic network of logical functions derived from the philosophy of BS 8110. The spreadsheet intelligently evaluates reinforcement layouts, balancing bar count, diameters, and section dimensions against code requirements, and then suggests the most economical and feasible distribution.  
     To illustrate,
    I've attached three screenshots along with the file itself:   
    Image 1 shows the case of an ideal distribution, where spacing and bar arrangement are both economical and code-compliant.
     shows the case of an ideal distribution, where spacing and bar arrangement are both economical and code-compliant.
     
    Image 2 demonstrates a costly distribution, where the file flags inefficiency and proposes alternative bar diameters or spacing to optimize the design.  
    demonstrates a costly distribution, where the file flags inefficiency and proposes alternative bar diameters or spacing to optimize the design
    Image 3 highlights a case of weak methodology, where the arrangement does not meet code requirements, and the file provides clear recommendations to correct the layout.  
    highlights a case of weak methodology, where the arrangement does not meet code requirements, and the file provides clear recommendations to correct the layout.  
     In practice, this interplay between section geometry and bar diameter is the essence of BS 8110's design philosophy, and the spreadsheet translates it into a practical decision tool.  
    I would be delighted if you try the file yourselves and share your valuable feedback. Your insights will be highly appreciated.

    That sounds cool and really complicated to a non-structural person like me, Abubakr. How did you test it to be sure it consistently provided correct answers?

    Thank you, Dr. William. You've touched on the most critical aspect of engineering tools: Validation.
    While the interface appears complex, its 'intelligence' is strictly grounded in the BS 8110 design philosophy. I have rigorously verified the output through manual cross-checks to ensure the total area of steel (As​) and bar spacing comply with the code requirements.
     
    To ensure reliability, the tool was tested against specific boundary conditions: it achieves optimal results for section widths between 150 mm and 1000 mm, and accommodates high-yield reinforcement diameters ranging from 8 mm to 28 mm. These constraints ensure that the 'logical' output remains within the realm of practical, safe, and buildable field applications.
     
    What makes this spreadsheet unique is that it isn't just a calculator; it's a Decision-Support Tool. It uses a dense network of logical functions (Nested IFs) to 'think' through the code's constraints-balancing economy and safety-rather than just processing numbers. It effectively translates engineering intuition into a digital logic.
     
    I believe that as we move further into the AI era, our role as engineers is to build 'logical guardrails' that ensure our digital tools remain faithful to the fundamental principles of structural integrity. I would be honored to hear your thoughts on this approach.

    Abubakr: It sounds as if you have designed the perfect approach to ensure that your spreadsheet produces correct results. When I worked for the Corps of Engineers we used a very similar technique for our TABS suite of open channel flow and sediment transport models. We employed a large number of standard tests to ensure that model upgrades and patches didn't compromise the models' ability to correctly solve the equations of motion. In the modern vernacular, it's called verification. A large number of tests were required to test all the possible loops and routines in thousands of lines of Fortran code. Then for each project application we compared the results to observed (hindcast) data and evaluated them for reasonableness in a process we now call validation.

    Thanks for posting.

    Thank you, Dr. McAnally, for your invaluable contribution and constant guidance. I find myself learning new meanings, concepts, and professional values from your insights every day.
    ​I truly appreciate the significant example you shared regarding the US Army Corps of Engineers and the TABS models; it underscores the robustness required in our professional work. My contribution was a modest attempt to tackle a large and complex issue, and while this post started as a way to break some 'computational dryness,' your participation has transformed that initial spark into a very valuable methodological foundation.
     
    ​I also want to thank all my colleagues for sharing their fascinating experiences. They prove that a skilled engineer, equipped with the right tools like Excel, can translate any vision into a living, dynamic tool.
    ​I have deeply enjoyed this inspiring discussion and learned so much from all of you. This is truly what defines our remarkable ASCE community.
