Yes, thanks! I was struggling and the formula builder says I can only use lambda as the function. Otherwise, I get a #NAME error. No I have a reason to use lambda. Thanks!
I liked how you started the presentation with a demo of the actual function, instead of leading us through wondering what's coming. But I LOVED when you started explaining the function with pen and paper. Nice analogue humanist connection. Thank you! 🙏
The function REDUCE is also very useful. In the last example, using REDUCE instead of SCAN you can obtain directly the cumulative sum of visits for every month.
Wow, thanks. SCAN combined with lambda function works very well in a running decaying series. I was using a too ordinary formula to handle this. Now you made it even more easier for me! For example, one may need to monitor a total budget supporting different items, how it goes down for every expenditure incurred. SCAN with lambda function in it makes it a straight forward approach🙂
What I love about scan and reduce is that they are able to make array formulas spill both vertically and horizontally. For example you can transpose the results of filter in the adjacent columns and at the same time make filter calculate vertically. A one cell formula with results in multiple rows and columns
Looking forward to watching your LAMDA video. It's taking me a long time to wrap my head around LAMDA. I am sometimes successful with it, but I don't know why!
Excel is the best Data Analysis tool till date. It is the jack of all but master of none. And that is the USP of this magical tool and also the weakness.
I have a worksheet that fundirnos like an inventory. It uses a vba user form to add a new entry for an item checked in or out. Could I use this scan function on a different worksheet to populate an inventory table that updates based on the first worsksheet?
I think the functionality is pretty new to PowerQuery as well. There was a time in both PQ and DA that to calculate the next sum involved going back to the first record and summing to the current record. It may well be SCAN that came first.
I have a table with hundreds of stock trades. I would like exel to auto generate a new unique ID for each trade as I add it to the table. I would like that ID to stick with the row that contains the trade even when I sort the table by various columns (such as date or name of stock etc.). I can get excel to auto generate a number using concate but that makes the numbers long and awkward. Is there a way to get excel to auto generate a Unique ID for each trade so that I can re-sort by ID and get them back in chronological order?
I saw another video which was about the new checkboxes and she was using NOW with iterative calculation turned on to make a timestamp when the box was checked. If the goal is a chronological sort I might try something like that.
I hadn't heard of choosecol and that spill range syntax before - handy. For a tutorial video I'd suggest naming the a & b parameters as acc & curr to make it more obvious which is which - that's how I name them when writing JS / C# etc
I am glad you found that helpful. Thanks for the suggestion reg. acc, curr. As most of my viewers have no coding experience, I went with a,b to keep it simple.
Thanks for all the Tips. Extremely useful Help needed on two topics. How do I use scan function to manage bank accounts? I have debit column, credit column and running Balance. Running balance is prev row balance + current row credit - current row debit. Can scan be used here. One another help is: for my investment tracking How can XIRR be calculated? The columns I have are Stock name, Buy date, sell date, buy value, sell value, current value [Current value is non-zero if sell value is zero, else it is zero]. With this 1. How do I get XIRR for each instrument i.e for each row 2. How do I get current XIRR overall? Thanks, Elango
I used the same way for quite a long time. But don't look past the function itself. The idea here is to demonstrate the function, put it in your toolbox, and figure out how to use it later in a novel way. (I haven't yet, but I'll come up with something :-) )
I still don’t understand the point of SCAN so why did he demo it that way and then switch to LAMBDA which made even less sense. I’m sure this function has some niche advantage but I don’t get it so I don’t think it’s gonna apply to my work.
What if I want a percent of total docs received by a column of dates. If there is a date it is received but I want to know how many is received by line
Great video, what about alternatives to calculatr dynamic moving averages , last 3 davys 7 days monthly quarterly etc ..and best approach from product analytics perfotmance point of view to make business sense of your data
The third example is perfect. Scan obviously saves a lot of typing and makes it easier to read. So definitely a nice thing. The first two examples are a bit... not well explained/sold. E5: =$D5 E6: =$E5+$D6 F5: =$D5 F6: =max($F5, $D6) And then just select E6:F6 and doubleclick the bottom right corner to get it copied to the following lines. If you wanted to make this a single formula for each column then you can use if and isnumber to get the formula on row 5 to handle the fact there are no values on row above, just labels. However changing order of the rows may ruin the fun, there the SCAN would be handy too. The third case can also be solved using a formula with ifs and conditional formatting. But it would look too messy. So I am happy there is a better way! Thanks!
Thank you. I agree we could do with a better / different explanation. That said, SCAN requires thinking about data in ranges and introducing that "new" idea would be a challenge if I had jumped straight to example #3.
Amazing video as always, but I struggle with a “NAME?” error even though I have followed your instructions, “=SCAN(0;C5:C15;sum)” and yes formula separators are semicolon where I live. Can it be something with the version of Excel?
Hi there... This is normal. The named shortcuts are rolling out to all users of Excel 365. Meanwhile, use this alternative syntax: =SCAN(0; C5:C15; LAMBDA(a;b; SUM(a;b)))
What if you have in collumn B the years showing multiple years (example last year and current year), collumn C month, collumn D showing In the Month Downloads. Collumn D showing year to date downloads. How to calculate collumn D running total within year ? Example from 2023 Jan till 2024 march, it shows the running total in collumn D of Jan-dec 2023…and running total Jan -mar 2024. Next to that is there also a way to apply this as calculated field within pivot table ?
You can use SCAN for such things too. The calculations get a bit complicated. For ex: =LET(years, COL_B, months, COL_C, values, COL_D, nums, SEQUENCE(COUNTA(values)), SCAN(0, nums, LAMBDA(a,b, IF(INDEX(months, b)=1, INDEX(values, b), INDEX(values, b)+a)))) The formula resets accumulator to first month value when month is 1. It also assumes you have only one row per year month combination. If you have daily data, you need to adjust the IF logic.
The performance would be better. Plus, as demoed later in the video, many times, you have no idea what the end point of the data is. So you don't know how far to drag or fill the formula down. SCAN helps in such situations.
@chandoo_ hm....but it also applys to SCAN function. If you don't know the size of the range you have to adjust scan function. Why not to use smart tables with the same easy function SUM($A$2:$a3)? The same result and you can always identify which range is used to do the calculation.

The average works in a different way than you think. for row 1 - same as the value in cell 1 for row 2 - average of first two valuesa from row 3 onwards - average of (previous average, current value) This is why the results appear wrong. But SCAN is doing what it is supposed to, which is to apply consistent average logic on previously "accumulated" value and the current value. To get running average of the list, you need any of these 3 functions: All of these assume your data is in E3:E12 1) Easy: =AVERAGE($E$3:E3) and drag it down 2) With Scan: =SCAN(,E3:E12,SUM)/SCAN(0,E3:E12,LAMBDA(a,c,a+1)) 3) With Let & MAP: =LET(arr,$E$3:$E$12, arr_count,COUNTA(arr), sq,SEQUENCE(arr_count), MAP(sq, LAMBDA(a,AVERAGE(TAKE(arr,a))))) I am sure there will other shorter and efficient options...
Can running total be conditional? First row is taken from a table, second row onwards it checks if number in upper cell is negative then taken from corresponding row of table, but if upper cell is positive number, then add upper cell & corresponding row of table. formula is like this in row =B2 and row 3 onwards =IF(F2

If your Excel version doesn't yet have the SCAN feature to directly use the shorthand version of SUM, you will see _xleta.SUM. Replace the formula with the longhand version below and it will work: =SCAN(0, D5:D16, LAMBDA(a,b, a+b))
You can do this with "let" You createva variable that counts the number of items in the list. Then you use that to create an array containing tjose numbers.
