Double Thunking Works Wonders!
Given that most Excel users would not dream of employing one thunk, you might well ask why even consider nested thunks! The use case explored here is to return all the combinations by which one might choose m objects from n (not just a count of options =COMBIN(n, m), but the actual combinations) Knowing that sometimes allows one to deploy an exhaustive search of options to determine the best strategy for a task. Before considering the task further, one might ask 'what is a thunk; isn't it far too complicated to be useful?' All it is, is a LAMBDA function that evaluates a formula when used, the same as any other function. The formula could be an expensive calculation or, rather better, no more than a simple lookup of a term from a previously calculated array. The point is, that whilst 'arrays of arrays' are not currently supported in Excel, an array of functions is fine, after all, an unrun function is little more than a text string. Only when evaluated, does one recover an array. In the example challenge, each cell contains an list/array of binary numbers, which might itself run into the hundreds of terms. A '1' represents a selected object whilst a '0' is an omitted object. Rather like the counts of combinations obtained from Pascal's triangle, each cell is derived from the contents of the cell to the left and the cell above. This is SCAN on steroids, accumulating array results in two directions. Running down the sheet, the new combination contains those of the above cell, but all the objects are shifted left and an empty slot appears to the right. These values are appended to those from the left, in which the member objects are shifted left but the new object is added to the right. So the challenge is to build a 2D array, each member of which is itself an array. The contents of each cell is represented by a thunk; each row is therefore an array of thunks which, for REDUCE to treat it as a single entity, requires it to be securely tucked inside its own LAMBDA, to become a thunk containing thunks. Each pair of rows defined by REDUCE is itself SCANned left to right to evaluate the new row. By comparison the 2D SCAN required for the Levenshtein distance which measure the similarity of text strings was a pushover. I am not expecting a great amount of discussion to stem from this post but, if it encourages just a few to be a little more adventurous in the way they exploit Excel, its job will be done! p.s. The title of this discussion borrows from the Double Diamond advert for beer in the 1960s
How to summarize by date range and grouping customer items
We have a table to summarize such that data is arranged by customer within specific dates. For example, 26 th to end of month plus the next 25 days as shown in this figure. How can this be done with dynamic array functions with possibility to change date range? E.g 16 th to 15 th, or 21 st to 20 th .
Word on iPhone
In the past, I’ve managed to edit some documents on my iPhone in Microsoft Word. But now Microsoft is slapping me in the face with grammatical suggestions that obscure my document. I don’t want any grammatical suggestions, but I can’t figure out how to make them stop. Can anybody suggest how I can do that? Am I in the right place to ask this question? Is there another place for the iPhone app?
Word mac issue
Hello, I want some help. I have a user who has a Mac Word file she needs to recover. She is stating that the file is hidden; she worked on the file, and then her computer restarted and lost the document. I told her to check the recycle bin to see if its in there. She said she created the file, modifying it from a previous file, and now it won't let her open the file. She then said this I found the missing text. The hidden document is visible in a shadow-like form. When she went to rename the document, there was no dot at the beginning of the file name. The renaming process did not result in the document being made visible? Can I get some help please?
Group Timeline chart by unique values
I have a table in an excel spreadsheet in which we plan the team's vacation days (fig.1) Note: in Brazil we can take up to 3 periods in a year - totalling 30 days - and 10 of those can be sold: you receive extra money and only take 20 days off on column B the worker puts his name, column C-D the worker inputs start and end day of each vacation period the other columns serve no purpose for the graph my question is about Then, I select A2:J13 range and create a pivot table/chart with the following fields (fig.2) My question is if there's a way to overlap the periods for a same worker (Samwise for example) Each worker should have only one line and all vacation periods be on it (because 3 years from now there would be so many lines that the graph wouldn't be nice to see the time periods each one is on vacation)

Where can I find the default settings for Table in Word? Currently when I insert a table, I might find the row not wide enough. And often, it was because of the row height being set as "exactly" and I have to set it as "at least". Where can I set the default as "at least" so that it does not always use "exactly"?
Microsoft Introduces Restore Capability for Conditional Access Policies
New Graph APIs allow Entra administrators to restore a conditional access policy with a Graph request. This article explains how to list, restore, and permanently remove soft-deleted conditional access policies using Graph API requests run in PowerShell. Being able to restore conditional access policies removed in error closes a big gap, especially if agents might begin working on policies. Who knows what errors might happen in future. https://office365itpros.com/2025/10/03/restore-a-conditional-access-policy/Countif/Countifs
I'm trying to do a standard countifs formula for several columns of information. Each column is using the same criteria but has different ranges. I'm trying to make an equation that will be easy to drag so I do not have to rewrite the range each time. Does anyone know how to do this? I have cells with the prewritten ranges I'll want to use. I can give more information if that helps people understand.
Macro to copy
Hello all you "Brilliant Minds" here is a chance to prove your "Excel-ence. I want to copy a value to one cell from the source which is random and as I haven't a clue about this stuff I asked Microsoft CoPilot. Being on the 4th version Where Microsoft excel still will not accept Microsoft CoPilot's creation, I am appealing to the Community. So here is your chance to prove that you are smarter than CoPilot. Here we go, everything but attach a file. If anyone is interested send me an email so I can send a couple of small files. Donald
What is the formula for counting each number from 1to25 that hits from each drawing?
I want to calculate the daily numbers for cash25 lotto. The numbers are drawn on Monday, Tuesday, Thursday, and Friday of each week. Six number from 1 to 25 are drawn each time. I have 157 rows and 7 columns (A-G). The first column is the date and Columns B-G are each number that was drawn. I know I need to do a count in each column of the total times each number is drawn. What is the formula I should enter? Help, please!
