Formula Challenge: The most efficient way to generate a Number Spiral (Ulam spiral) ?
The goal: Ulam spiral - Wikipedia The trick is creating a function capable of producing the largest matrix of numbers possible (this may rule out the recursive approach). The approach I took: The approach I took was creating 'frames' and working inward with REDUCE essentially performing repeated addition: REDUCE works its way through an array of odd numbers in descending order (1 is omitted) with 3 different situations: 1. The odd number is the largest so the matrix does not require padding. 2. The odd number is 3, the anomaly, so a 'padded core' is created. 3. The odd number is not the greatest nor 3 so a padded matrix is generated Spiral Lambda: =LET( s, ODD(INT(SQRT(n))), arr, UNIQUE(ODD(SEQUENCE(s - 1, , s, -1))), arrCore, {5, 4, 3; 6, 1, 2; 7, 8, 9}, IFERROR( REDUCE( 0, arr, LAMBDA(a, v, LET( TopBottomPadding, EXPAND(0, (s - v) / 2, s, 0), SidePadding, EXPAND(0, v, (s - v) / 2, 0), top, SEQUENCE(, v, (v - 1) ^ 2 + 1, -1), bottom, SEQUENCE(, v, (v - 1) ^ 2 + v, 1), left_frame, EXPAND(SEQUENCE(v - 2, , (v - 1) ^ 2 + 2), , v - 1, 0), right_frame, SEQUENCE(v - 2, , (v - 1) ^ 2 - (v - 1), -1), core_stuffing, EXPAND(0, v, (s - v) / 2, 0), core, VSTACK( TopBottomPadding, HSTACK(core_stuffing, arrCore, core_stuffing), TopBottomPadding ), center, HSTACK(left_frame, right_frame), nopad, VSTACK(top, center, bottom), pad, VSTACK( TopBottomPadding, HSTACK(SidePadding, VSTACK(top, center, bottom), SidePadding), TopBottomPadding ), a + IF(v = s, nopad, IF(v = 3, core, pad)) ) ) ), "Please enter a number 17 or greater" ) ) The accuracy checks The highest number I've been able to get away with for n is 300,001. I'm interesting in any suggested improvements or different approaches to this task!Tokyo Stock Exchange data
Does any one know, and can share, a sample excel file that can import updated information (ticker, name, last price, dividend yield, daily high and daily low and analysts average target price) for ~50 stocks traded on the Tokyo stock exchange, which is not covered by Microsoft?
Outlook for Mac missing ToDo
Since a recent update, our Mac clients don't have any way to view ToDo or Tasks in the New Outlook. The tasks don't show in the My Day/Task pane, nor do we have a ToDo Icon ion the left sidebar like users of New Outlook on Windows do. Accessing OWA is now the only way for users to see tasks/flagged emails, but very much not the preferred solution since there IS a desktop client which should do that. Microsoft® Outlook for Mac Version 16.105 (26011018) This is a serious usability issue, is this really a design decision or some sort of an issue?"Method 'Calculation' of object '_Application' failed" error occurs on unpredictable attempts

Creating a live document
Hi All, I wonder if anyone could help me please or guide me in the right direction. We are a small charity who provides free transport for Cancer clients in our area as our nearest hospital is over 60 miles away. Once a week we produce a 'Run Sheet' in Word, convert it to a PDF and email the link of the file to all our drivers for their duties the following week. The problem we have is the sheet is out of date the minute we send it out as clients call continually and new 'runs' are added. We prefer PDF as our drivers (some with limited tech skills) have PDF Readers by default on their smart phones. Whether it's word or PDF, how could we create a 'live' run sheet so that when the co-ordinators add or change the 'run sheet' within our OneDrive the drivers can see this. I know the basic level of this is to just create a Word document and create a share link and send that but I am sure there will be a better way of doing it so that we can point 'one' link and not have to share the a different file each week. Is there something within the Microsoft Family that would do the job better? We have a full non-profit licence. Sorry if that is confusing. Any ideas are most welcome. Thanks, Andrew
MS Word is throwing up 'Error 4608' I haven't a clue what to do.
Hello, I wonder if anyone can help me here, because I am at a TOTAL los... I have a Word document that I have been updating for a few years, which is a sort of log. It has worked well up until today. Now, whenever I try to save the updated document, a very old fashioned (looks like Windows 3.1!), error message window appears which is headed 'Visual Basic for Applications' and in the window it says: Run-time error: '4608': Undefined dialogue record field There are then four buttons at the bottom labelled Help, Continue (which is greyed out), End and Debug. I have no idea what this error message means. Clicking on End gets rid of the error message, but prevents me from saving my updated document, and the next time I try to save it the error message just reappears. Clicking on Help takes me to a website with the title 'No F1 help match was found', followed by a load of technical computer-geek stuff I don't understand. Clicking on Debug seems to open a new window, but I do not know what it is... Here is a screen-shot of it: The highlighted text seems to refer to Bookmarks, which is throws me because I only associate Bookmarks with my web browser, not MS Word. I'm sure I haven't added any bookmarks to my document in any case. Can anyone enlighten me as to what is going on here please? Thanks
Allow removal of "Copilot Suggestions" from right-click menu
I have been using Excel for decades and CONSTANTLY use the right-click menu for quick access to basic functions (e.g., "Insert"). Ever since "Copilot Suggestions" was added to the drop-down list, it always throws me off due to its placement. I have Microsoft 365 on Windows 11 Pro. I have searched for ways to remove this from appearing there and the result said "go to File > Options > Copilot and uncheck the 'Enable Copilot' box". However, when I attempt to do that, there is NO "Copilot" option available! PLEASE allow removal of "Copilot Suggestions" from the right-click menu OR at least the option to move it to the bottom (so it isn't in the way of things used ALL the time). I realize that Copilot is a great resource for many users, but I am confident in my Excel skills and in my ability to research/learn new skills the "old school" way, so I have little use for this feature now and would prefer to hide it.
microsoft excel import text file template
I used the Text Import Wizard to create an excel document from a text file. My data does not have nice commas, semicolons, tabs, or spaces. My data is a fixed width. My data is by the columns like 5, 10, 12, 14, 20 column. It takes a long time to set the correct columns. I then saved it as a .xltx file to create a template. Then I expected to be able to use the template in the future. I tried to create a new excel file with the .xltx template I just created. When I pasted data into the new excel document my data was not organized. What am I doing wrong? Save as an Excel Template: Go to File > Save As, and select Excel Template (*.xltx) from the "Save as type" dropdown. This saves your layout in the custom templates folder. Use the Template: When you want to import data in the future, open this template (File > New > Personal), then use the import steps above to place the external data into your predefined format.
Error al modificar una antigua formula
Estoy intentando modificar una formula que tenia antes unicamente cambiando lo que es la cantidad por la que se sumaba a la que tenia la anterior, lo demas de la formula esta completamente igual, pero por alguna razon me salta esa pestaña diciendo que hay algun problema con la formula, estuve buscando si hay algun tipo de error pero no lo encontre, inclusive llegue a copiar la primera formula original y no funciona aun asi, por mas que lo intento siempre me salta la misma advertencia y no me deja agregar la formula como es debido. cabe decir que la formula es la que esta abajo de la pestaña de advertencia y la celda "B10" es la de la cantidad de "300,000" que esta encima de los "354,000"
