Thank you so much for pointing out the LET (and IFS) functions. This has drastically simplified a very complex formula we have been using. Our existing formula was 1615 characters in length, and with just the LET function it reduced the formula length to 487 characters. With a combination of the LET and IFS functions, it reduced the length of the formula to 469 characters. Here is the end result using LET & IFS: =LET(x,INDEX(TableName,MATCH([@sale],[sale],0),MATCH(Adj1_Element,TableName[#Headers],0)),a,Adj1_a,b,Adj1_b,c,Adj1_c,d,Adj1_d,e,Adj1_e, IFS( Adj1_Graph_Type="Exponential",a*EXP(b*x), Adj1_Graph_Type="Linear",a*x+b, Adj1_Graph_Type="Logarithmic",a*LN(x)+b, Adj1_Graph_Type="Polynomial (2 order)",a*x^2+b*x+c, Adj1_Graph_Type="Polynomial (3 order)",a*x^3+b*x^2+c*x+d, Adj1_Graph_Type="Polynomial (4 order)",a*x^4+b*x^3+c*x^2+d*x+e, Adj1_Graph_Type="Power",a*x^b, TRUE,"")) While I have not measured any performance improvement, since I have only run a limited test, I am sure it is there.

The addition of the LET function means that Excel formulas are basically becoming like a programming language where declaring variables is the norm.

Great video... as always :) When you have tables with long column names and these get repeated in formulas it can make them really hard to read, so using LET will make these much easier to read and maintain - all we have to do is look at the variable at the beginning and we'll see which columns this refers to throughout.

Leila, I'm a heavy excel user and I love your videos ! You are always clear and to the point. Greetings from Brazil !

I've been grumbling that Excel should have this feature for years. Now i'm super excited!

Indeed! LET function would be a one of the most with FILTER function to make the excel more powerful. Thank you for sharing the great knowledge

Started watching your videos for the view and then realized that I learned lot of short cuts in excel. Thanks great job

This is great.Many thanks for this tutorial quiet straightforward and impactful. I see let function working more like the variable function in powerbi.

That second example is crazy, I'm guessing because it can grab the complex function from the variable established, instead of reading it each time it is faster; however, when doing small calculations the time to set the variable initially ever so slightly outways the benefit in cost of time. REALLY awesome stuff, can't wait for that official launch.

Thank you for your vids! I apply some of your tutorials to the work I do. It’s been a major help!

A very thorough treatment of this little useful function. Speaking of performance, I remember how, about the time you were born, a 100 x 20 sheet was recalculated for several seconds (VisiCalc on Apple ][), and auto-recalc was usually turned off.

Thanks Leila! a great example of productivity.

Great to see speed tests on LET function!!! Think it's the first one out here. Many thanks for that!!. A great advantage of LET is it's kind of portability. We can write a complex formula in one workbook, copying it as a string, pasting it in other workbook , changing only the variables reference addresses , and good to go. No VBA😉

I have found that most speed improvements are negligible unless dealing with large datasets. The kind of datasets not typically seen in small businesses. BUT, I have always been a fan of making formulas readable understandable at a glance by someone that did not wite the code. I am frustrated sometimes when analyzing someone else's code when they do not use common conventions or make use of named ranges. Most people can understand Assets=Capital - Liabilities easier to read than some combination of summed cells - other summed cells.

Thank you for another great video! You inspire me

Hey Leila, Thanks for this tutorial of new LET function. This is surely going to improve file performance and make long formulas easier to read.
