What do you think of thunks?
OK, so the most likely response by far is going to be "I don't". However, I tried one of Omid Motamedisedeh's regular challenges and found it a suitable problem for exploring some of the lesser known byways of modern Excel. The challenge is to pick out locally maximum values from a rolling range. What I did was to write a function that used MAP to select one cell at a time, using DROP to remove the initial cells and TAKE to return a range of 5 cells with the active cell in the middle. The direct route to solving the stated problem would be to calculate the maximum value within each range immediately, but I was interested in the more general problem of "could I return the array of ranges in a form that would support further analysis?" As shown, the following formula ROLLINGRANGEλ = LAMBDA(values, n, LET( rows, SEQUENCE(ROWS(values)), MAP(rows, LAMBDA(k, LET( m, QUOTIENT(n, 2), rng, TAKE(DROP(values, k - m - 1), MIN(k + m, n)), rng ) ) ) ) ); gives and array of ranges error, but simply by enclosing the 'rng' variable within a further LAMBDA ... LET( m, QUOTIENT(n, 2), rng, TAKE(DROP(values, k - m - 1), MIN(k + m, n)), LAMBDA(rng) ) will cause Excel to return an array of functions, each one of which would return a range if evaluated. In the attached workbook, a number of formulae are based upon this array of functions = ROLLINGRANGEλ(dataValues, 5) = MAP(ROLLINGRANGEλ(dataValues, 5), LAMBDA(ϑ, ROWS(ϑ()))) = MAP(ROLLINGRANGEλ(dataValues, 5), LAMBDA(ϑ, ISREF(ϑ()))) = MAP(ROLLINGRANGEλ(dataValues, 5), LAMBDA(ϑ, AVERAGE(ϑ()))) = MAP(ROLLINGRANGEλ(dataValues, 5), dataValues, LAMBDA(ϑ,v, MAX(ϑ()))) = LET( rollingMax, MAP(ROLLINGRANGEλ(dataValues, 5), LAMBDA(ϑ, MAX(ϑ()))), FILTER(Data, rollingMax=dataValues) ) The first simply returns #CALC! errors on the worksheet which is the normal response to a Lambda function defined on the grid. The second formulas uses ROWS to show that the ranges are not all the same size, the third shows the returned objects to be range references and not simply arrays of numbers, the forth is a rolling average while the fifth is a rolling MAX. The final formula returns the solution to the problem, being a filtered list. The purpose of this post is to demonstrate that Excel, which started out as a 'simple' spreadsheet program, now contains a very different programming environment that shares a function library and uses the grid for input/output but, other than that, has very little in common with 'normal' spreadsheet practice!

IFS or anyother function
Dear Experts, I have a data like below:- So, Column "B" - sfn can go from 0 ~ 1023, and Column-"C", can go from 0~19, Column "G" has 3 values(rnti's) - Now, we have only 2 situations like below in Column"E", where I need the formula:- Either all these 3 rnti's can be Multiplexed in the same sfn.slot So, in below snip all 3 rnti's are FDMed in same sfn.slot - 394.6 and should be continuous, so Column "E" should have fdm-3 But in below instance, in 395.2 we have only 2 rnti's multiplexed(so fdm-2 should be populated) Attached is the spreadsheet. Thanks in Advance, Br, Anupam
copy data from one excel worksheet to another automatically based on yes or no
I am trying to build a "database" to track ongoing service issues. I currently track all service jobs (roughly 20/day), on individual tabs and have a separate tab for jobs that were not completed after 1 visit to ensure visibility is maintained and the job isn't lost. This "Ongoing Issue Tracker" is managed manually today. I am trying to add a cell on the daily sheet for each job that will auto populate the "Ongoing Issue Tracker" based on Conditional Formatting (Yes or No). I am striking out so far, any thoughts or help is appreciated!!File for work. please help!
Hi all, i have a file that i use for work. Right now there are 2 different pages. a list of the items with their code and an info about their situation. For Example if they are out, lost, etc. a list of numbers that i send next to the date. if they come back they are yellow, if not they are red. i do all of this manually every day, but when i am not in the office no one does that because it's long, boring and probably very confusing. Ideally i need something that keeps track of what goes out and what comes back and the dates. i attached the two pages. any help, advice, would be highly appreciated!! Many thanks!
Adding COUNTIF formula to cell by VBA code
Morning all, need some assistance. Attempting to insert a new formula by VBA with an already working Macro. All the other references unhighlighted below work perfectly, but I am missing something with the syntax around a countif function. The countif currently works on the excel sheet itself, however adding it into the VBA is generating the typical "Compile error: expected: end of statement" error indicating a syntax problem. Any advice?
