Cannot add a worksheet to my Excel spreadsheet
I haver all of a sudden lost the ability to add worksheets to my spreadsheet program. I am using macros that both protect and unprotect the sheets that are currently there, but I want to add another sheet, and the plus sign at the bottom is grayed out as well as the 'Insert Line' line when you do Home/Insert. I have looked and I cannot find the setting that controls the addition of worksheets. Any suggestions???
Cumulative Sum of Each Column or Row
After studying various posts (answers) by members of this community, I developed a function that returns the cumulative sum of each column or row of an array: =LAMBDA(a,[by_row],LET( f,IF(by_row, LAMBDA(b,IF(ROWS(b)=1,b, LAMBDA(b-VSTACK(0,DROP(TAKE(b,,-1),-1)))())), LAMBDA(b,IF(COLUMNS(b)=1,b, LAMBDA(b-HSTACK(0,DROP(TAKE(b,-1),,-1)))()))), IF(by_row, LAMBDA(f(SCAN(0,a,SUM)))(), LAMBDA(f(TRANSPOSE(SCAN(0,TRANSPOSE(a),SUM))))()))) My goal is maximum efficiency. I am new to the concept of lazy evaluation, so I'm wondering if you could explain the flow in detail and whether there is a pair of sets of parentheses too much. Of course, I'm open to improvements.
How can a remove these files from the 'Recent' list?
How can a remove these files from the 'Recent' list please? I've deleted these workbooks from OneDrive, but they still appear in the Recent list. How can I stop them appearing every time I open Excel please? I've tried uninstalling Office and reinstalling. I'm using Office 365. Thank you!Date entered is changed to a different date
This issue has just started as far as I can tell. On an existing worksheet with the column formated to "date" 01/01/2025 format - when I enter a date of 01/01/2025 as for an example and hit "enter", the date is changed to 10/29/70! If I enter a date of 01/19/2026 it is changed to 08/27/63! and so on,..... it changes the field every time. if I enter those same dates by physically entering 01 slash 19 slash 2026 slash it will stay as I typed it - and will look like 01/19/2026 (or 01 slash 01 slash 2025) My husband is able to create a spreadsheet on his laptop that works correctly. When he sent it to me, the date fields did what I have stated above. So there must be something corrupt on my laptop? or Excel? I am running on the latest build (to my knowledge) Anyone? I am at a loss.. When entering a lot of data and dates - this is a real PIA. Plus - it was working just fiine - not sure what has changed. Thank you
Python in Excel is enabled but the runtime never downloaded
Hi, Python in Excel is enabled but the runtime never downloaded. Excel returns `/app/officepy/bin/python`, but the runtime folder is missing and HTTPS fails inside the sandbox. This is the ghost-runtime state. Please escalate to the Office engineering team to reset rollout flags and push the runtime package to my device. Excel build: 16.0.17231.20182 (Current Channel) ODT repair: fails with “couldn’t install” AppContainer: registered but empty Runtime folder: missing under %LOCALAPPDATA%\Microsoft\Office HTTPS: 400 errors inside Python sandbox I tried everything possible with Co-pilot's help. I tried reinstalling office full repair and ODT reinstall attempted. The runtime package never downloads. Apparently, This requires a rollout flag reset. Please help thanks
msoFileDialogFolderPicker compiler error
I have searched the net and not seen this issue. I developed a stand alone program in Excel Vba using msoFileDialogFolderPicker. It runs no problem. The function is as follows: Function PickFolder() As String With Application.FileDialog(msoFileDialogFolderPicker) If .Show = -1 Then PickFolder = .SelectedItems(1) End With End Function This was then added to a larger program with exactly the same code on the same PC and I get 'compile error' variable not found with 'msoFileDialogFolderPicker' highlighted.Excel Challenge - Pivoting poorly structured data
This is from an ExcelBI challenge. I thought it may be worth while posting my solution here as a demonstration of modern Excel methods. Challenge Like many of such challenges, the natural solution approach is to use BYROW but that creates the usual 'array of arrays' error. Solution: Gradually I am moving to a point at which I have no formulas showing in the workbook other than calls to Lambda functions. In this case, the worksheet formuloa is = PIVOTBYCATEGORYλ(OrderTbl) The function works row by row apportioning the amounts against the listed categories PIVOTBYCATEGORYλ // Groups and pivots table by category = LAMBDA(table, LET( normalised, BYROWλ(table, APPORTIONλ), // Identify fields from normalised table dimension, TAKE(DROP(normalised,,1),,2), category, TAKE(normalised,,1), partCost, TAKE(normalised,,-1), // Pivot by category return, PIVOTBY(dimension, category, partCost, SUM,,0,,0), return ) ); The function APPORTIONλ divides the amount between categories so each record within the source data returns a number of rows APPORTIONλ // Splits by category and assigns costs = LAMBDA(record, LET( category, TOCOL(REGEXEXTRACT(INDEX(record,4),"\w+",1)), amount, INDEX(record,3) / COUNTA(category), year, YEAR(INDEX(record,1)), region, IF(LEN(INDEX(record, 2)), INDEX(record, 2), "Unknown"), broadcast, B∕CASTλ(HSTACK(region, year, amount), category), return, HSTACK(category, broadcast), return ) ); /* FUNCTION NAME: B∕CASTλ DESCRIPTION: Broadcasts the terms of a vector over the shape of a second array */ B∕CASTλ = LAMBDA(vector, array, IF({1}, vector, array)); The key to making the formula work is the function BYROWλ that I wrote to generalise the inbuilt but over-restrictive BYROW function. The PIVOTBY function returned the required crosstab from the normalised data array
