Do I know Excel? Not at all. People call me an Excel trainer but I think every time I watch an amazing video of yours it just makes me feel, super awesome. Thanks a lot for all the wonderful video content you keep posting.
The most powerful statement you made was right at the end. The next generation of excel users will be intuitively learning functional programing techniques. I suspect that this was perhaps the deeper reason behind Simon Peyton Jones decision to join Microsoft. Personally I am delighted as I know from experience that it takes time to become fluent with these techniques.
Absolutely agree. I was in the camp that VBA aged, and we should provide support for language such as Python/ R natively in Excel. But after seeing these recent paradigm shift in Excel programmability, I'll agree that I was short sighted. Any general-purpose programming language is a distraction for the population who uses Excel. I am a programmer, and still love Excel as it allows you to focus on the activity rather than how to do it. Lambda (and all the recent functions to support it) feel so tightly integrated. This is probably the best evolution in Excel, ever.
That’s interesting-SPJ has worked a lot on the same kinds of things-perhaps with more emphasis on formal methods intersecting with domain languages. He seemed to weigh in stuff like formal methods in secure operating systems, while still being hyper focused on thinking about language ecosystems like his comparisons about Java. Having just stopped running a company I am back in a job in finance, yet I still have a heavy addiction to programming. This is giving me exactly what I need to stay interested in what I’m doing. I’m seeing that there’s actually good structure here-and it is textbook ML style FP. However I still get bugged by the functions not being first class polymorphic functions where you can pass in labels with values dependent on higher order functions though. Example…I’m typing in a structured reference this morning like to a table called [APR] which is also a name of a table column like [@[APR]], and yet there are no operads for me to touch the concept of the string-it’s still objects. It’s still something that is not well defined in the sense of Grothendieck Universes, Agda, or even Haskell’s system F. Another example-I’m writing a Sumif with structured references and embedded conditional criteria-but it’s dax sometimes and it’s something else other times. I can’t know how the value will be represented in memory-will an embedded conditional be passed up to a Calling function, hit a type error I never see, or is it simply an undefined parameterization because the designers didn’t intend for users to make criteria into multi-function call chains? I’ve been in the lisp world a bit more than usual these past several months entertaining myself with nix and I can never imagine doing series fast paced corporate work with those-only building systems. And yet these don’t have the barriers that make it harder to express deep relationships about data and the many people oriented issues around that data. You’ve gotta write most stuff yourself, and outside of excel it’s not gonna be in some nice text editing space where the rules are standard. For example, no two emacs configs are alike. Just check out the many inconsistencies in packages between scala, OCaml, python, R, Rust, or Clojure, all kinda functional interfaces but not completely pure or well founded, and yet they still don’t really have great workspaces like an excel sheet or a power query editor. Kinda amazing.
Leila, watching your videos is like the quote: The MORE I know, the more I know How LESS I know.... Thank you for your efforts to make us understand this powerful function Lambda... Super Exited to start applying it for the tasks which were incomplete in past without looping functionality in Excel built-in functions
Great!! Wrote a recursive lambda that can handle the whole string column array RPLAB(ar,a,b,i)=LAMBDA(ar,a,b,i,LET(r,ROWS(a),IF(i=r+1,ar,RPLAB(SUBSTITUTE(ar,INDEX(a,i),INDEX(b,i)),a,b,i+1)))) --replace a with b for array ar and i=1 If you don't like extra variable i we write another one REPLACEAB(ar,a,b)=LAMBDA(ar,a,b,RPLAB(ar,a,b,1)) Anyhow "i" can be very handy in case you want to start the search from a different index in the replace list.
Great explanation of this concept. Note that the name you give your parameters will appear in the function screen tips (the little pop-up that comes under your function when you are inside it). So if you name them "Text", "Before" and "After" instead of t, b and a, then it will be much easier for the user to figure out what to input in each parameter.
Another Thursday 'Must-Watch' date with Leila … but today's OMG moments required a pot of black coffee to watch both Lamdda videos three times … and I still have much work to do. For me, many of these functions are like getting a drink of water with a firehose … but the ideas … ideas … ideas are numerous!!! I leave hard copy post-it notes and digital post-it notes all over my financial models to remind myself to review again and incorporate Leila's lessons. Overwhelming … but so good … so well explained. As always … your are a treasure … thank you … thank you … thank you …
Trust me, it took me a long time and a lot of post-its to get the hang of it. But when it finally clicks it offers so many amazing possibilities. As always, thanks for your support!
Brilliant, Brilliant, Brilliant. LAMDA stuffed with IF, SUBSTITUTE and OFFSET WoW !!. I think this function was invented by someone eating stuffed Turkey in a thanks giving dinner. Amazing decoding. What a function to close 2020 ! Cheers Leila !
@@4verse79 VBA functions are notoriously slower than inbuilt excel functions. LAMBDA essentially allows you create custom inbuilt functions at the speed of the inbuilt functions.
Hey Leila, Big fan and have been watching you for years. I recently came across the magic of Map and Lambda in Google sheets / Excel and I would definitely would love to take it for a spin. I haven’t had the chance to use recursive lambda but one day, for sure.
I knew that Excel is very powerful but that powerful is shocker! Thanks Leila for teaching that other dimension of Excel so advanced and yet practical!
Wow, I have puzzled over this for years. Thank you for explaining this. The function is like repeating mirrors that reflect off of the most recent reflection, but the difference is that in Excel you can program the way out for that latest reflection/replacement. This was very helpful!
Used Python for most of my data work but at my new job was forced to use Excel. Your tutorials have been a blessing. Really appreciate the work you put on these!
With BYROW and BYCOL this example can be done a lot easier, with the difference, that you will have to select the whole range of replacement words and not just the first cell. Thanks for the F2 tip in name manager that was super anoying until now.
Wow. It's a Christimas gift before Christmas. I just activated the beta channel so I be able to use Lambda. It will save me a lot of time and make my workbook easier to understand.
Wow, Leila! This example is exceptionally cool in that it would allow you to add to your list of errors(b) and corrections(a) that it can fix without any change to your formula.
Wow, i am blown by the power of this function. Excell is slowly stepping into coding territory my head is still spinning but I will get it. thank you Leila :)
Lambda functions are really powerfull. We, the developers, don't even know how much it will impact sheets creations from now on. I can already see people creating libraries full of personalized lambda functions to expand what Excel can do. I didn't really had time to do it, but I imagine that we finally can have fully optmizable neural networks or genetic algorithms working in Excel without any VBA or usage of Solver, just with lambda functions.
Oh, Leila - this is an eye-opener! Thanks for sharing your knowledge. Actually I've got so many ideas to realize with LAMBDA, but recursive functions double the impact of this function. Can't wait to get the function at my insider-installation. Und ich hoffe auf 2021! Frohe Weihnachten und bleib gesund, Andreas.
You make it look so easy, yet I’m sitting here thinking you’re using some form of magic. 🧐 What? How? 🤪 I love watching an artist at work. The ability to start with nothing and end up with something beautiful.🤩
This opens up Pandora's box, Now we have a tool to work on - try and try. Relate to our previous work, test where you can use it and create future intelligence. Thanks a Lot Lela
You have an excellent brain! This is very complicated, but you make it appear reasonable when you are explaining it. After you were done I realized that it is beyond me. However, it was wonderful and interesting just to listen to you.
Cristal clear! As always! Hmmm, I think I'm repetitive lately. I'm running out of appreciation adjectives for your pearls on Excel 😀😀😀 Leila, Bravo Zulu!
Great technique! This technique won't be clear to you if you dont understand loops in programming. With good understanding of loops, this Lambda technique would be clearer. Coding skill is becoming a must for the next gen of Excel power users really.
Hi Leila. Awesome lesson and example! I love making VBA UDFs and it is kind of sad that VBA is at a dead end in terms of attention from Microsoft. But, these LAMBDAs look like fun and super powerful. Looking forward to testing them soon. Thanks for sharing :)) Thumbs up!!
Woaahhhhhhh!!!!..... You are simple awesome!!!.... I was using a approx. 100 line code in VBA to make this work...... Now this is simple superb, swift....
It is better than using find and replace functions. Hopefully everyone can get to use it soon. Thanks for the long detail explaining of the use for this Lambda functions.
Extremely useful - thanks. As a sidenote, you had to use recursion to actually implement iteration - this goes to illustrate that every recursive algorithm has an equivalent iterative one, and vice versa.
Hi Leila. Awesome! I developed recursive functions when programming in LISP years ago, with a twist in that the function was able to modify iteslf on the fly during recursions and do things that I couldn't figure out how to implement any other way. I have missed that power since moving on to other languages. Great to see this functionality in Excel!
Hi Bob, I guess anyone of us is waiting for it. I've got three tenants and installations with different Insider installations, but no LAMBDA at all :-( Merry XMAS. Hope to see you next time in London or Amsterdam.
So finally the Thursday Video on LAMBDA is here! Thank you Leila for the nice example and simple explanation! Now waiting for this to become common to all users from Microsoft, for using it practically in some of my data processing challenges! 😊👍
Very cool! I was intrigued about how lambdas would handle loops. This was an exceptional demonstration of skill 👍 I personally doubt the lambda function will go past anything but a curiosity in excel, but who am I to tell?! Would I ever want anybody to learn this? Heck no! Way too risky and again, only valid if inside a given workbook. Try asking anyone in the accounting department to audit Yves’ function now that I am sipping margaritas on an island!! Great outlier in the world of excel functions😊
This is going to help in many more ways which is hard to perceive at this moment as the function is new and limited in examples. Look forward to more examples in its application.
Another great video and wonderful explanations. I still don't have this LAMBDA function but, thanks to you, I'll be ready for it. At last, I hope so. ;-) Oh, and I love it when you say "…here is how things can get complicated…". With Excel and people like you, life is never boring, there's always something to learn. So, a big thank you.
I have NO IDEA how you managed to pack so much into a video that length. I had a column of data where I need to strip out multiple extra words before and after the value I wanted to end up with. I tried it with a series of SUBSTITUTE commands, which worked, but required me to create a new column for each pattern to replace. Then I tried it again using your MegaReplace, and it worked like magic!
Hi Leila, Based on this I tried multi filter.. scenario is there are 5 filter criteria based on selection of filter criteria we need to either filter 1 r 3 r 5. We can use filter with + or* as filter criteria is dynamic..
Hi Leila - Big fan of your content, thanks! Apologies in advance, if someone else already made this suggestion. I think you should emphasize that the BEFORE/AFTER values should NOT be a table. While following along with the exercise, I made them both tables, which introduced an issue at runtime. SKILLS needs to be at table, but BEFORE/AFTER should not. I hope that explanation makes sense. Super cool function. Also, why is OFFSET volatile? I see a video on this function so I'll go check it out :)
Good one. I also solved tried solving this substitute and offset but was not able to complete because I couldn't make out exit strategy. I couldn't thought of it. Well done.
WOW!!!! I have to play with this... working with large datasets with ‘incorrect’ nomenclature in 4 columns to standardize before pricing and importing - wow. I’m loving your vids, and will be signing up for your courses once my transition to corporate finalizes!
Yep - it was definitely worth the wait since watching part 1! Thanks and liked the simple yet effective explanation on the term 'recursive', especially with the visual flow aid
