Adding to a formula
Hello, I need to add more to the formula we currently have, but not sure how to add it in. how can i add the value of L & PH so it takes 1 away for the value of L and 0.5 away for PH. (Holiday bkd cell) =IF('SetUp Tab'!$E$6="No",(COUNTIFS($A$13:$A$377,">="&$A$1+1,$A$13:$A$377,"<="&$A$377,Q13:Q377,"H")),(COUNTIFS($A$13:$A$378,">="&$A$1+1,$A$13:$A$378,"<="&$A$378,Q13:Q378,"H"))) (holiday taken cell) =IF('SetUp Tab'!$E$6="No",(COUNTIFS($A$13:$A$377,">="&$A$13,$A$13:$A$377,"<="&$A$1,Q13:Q377,"H")),(COUNTIFS($A$13:$A$378,">="&$A$13,$A$13:$A$378,"<="&$A$1,Q13:Q378,"H")))
Excel: Count cells with specific value + colour
Hi there, I would like to be able to count the number of cells that contain a specific value and are shaded a specific colour. This is for a rota spreadsheet that will be tallying the total number of shifts which have been agreed. The cells that contain "Yes" as a value from a drop down list and are shaded green, should be counted as part of the quarterly total. I'm assuming that a VBA custom function would be needed for this. I've tried a few but cannot figure out a way to get this to work with both a specific value and colour. I would be very grateful for anyone that is able crack this challenge. In the example screenshots, it is the cells shaded in green that would need to be counted and the totals appear in column GJ. Best regards, Daniel
The Diagonal Suite: Gentle thunking goes a long way!
I've become a big advocate for gentle thunking - using thunks to delay eager evaluation wherever possible in generalized Lambda development. The timings are quicker and the logic is cleaner. On the other hand, thunking the results of MAP, BYROW, or BYCOL - especially when it leads to rows of thunks - tends to introduce recombination overhead and complexity. I think thunking is often dismissed as “too complex,” and that’s understandable if someone’s first exposure involves unwrapping a row of thunks. When used gently thunking becomes indispensable. Typically, I introduce the thunks after the initial benchmarking to see the difference in the calculation times and the after is always quicker. To illustrate, I’ll share The Diagonal Suite - a collection of functions where thunking is used at every opportunity. Simple, clean, deferred logic. What are your thoughts on gentle thunking? Where have you found it helpful/harmful in your own Lambda development? //The Diagonal Suite - Version 1.0 - 10/27/2025 //Author: Patrick H. //Description: Directional traversal and diagonal logic for 2D arrays. // Functions: // • Traverseλ - Directional traversal engine // • ByDiagλ - Diagonal-based aggregation // • DiagMapλ - Wrapper for diagonal matrix extraction // • DiagIndexλ - Targeted diagonal extraction // • Staircaseλ - Construct diagonal staircases from a vector or 2D array //──────────────────────────────────────────────────────────── //------------------------------------------------------------------------------------------- //Traverseλ - Directional Axis Remapper //------------------------------------------------------------------------------------------- //The selected axis is remapped to the top-left traversal order. //Accepted directions: // "NE" or 1 → Northeast (↗) // "SE" or 2 → Southeast (↘) // "SW" or 3 → Southwest (↙) //Parameters: //array → 2D input array (scalars not accepted) //new_axis → Axis direction ("NE", "SE", "SW" or 1–3) Traverseλ = LAMBDA( array, new_axis, //Input validation IF(OR(ROWS(array)=1,COLUMNS(array)=1), "#2D-ARRAY!", IF(AND(ISNUMBER(new_axis),OR(new_axis<=0,new_axis>3)),"#AXIS!", LET( //Dimensions i, ROWS(array), j, COLUMNS(array), //Axis traversal indices (deferred) x_NE, LAMBDA(SEQUENCE(j,,1,0)*SEQUENCE(,i)), y_NE, LAMBDA(SEQUENCE(j,,j,-1)*SEQUENCE(,i,1,0)), x_SE, LAMBDA(SEQUENCE(i,,i,-1)*SEQUENCE(,j,1,0)), y_SE, LAMBDA(SEQUENCE(i,,j,0)+SEQUENCE(,j,0,-1)), x_SW, LAMBDA(SEQUENCE(j,,i,0)+SEQUENCE(,i,0,-1)), y_SW, LAMBDA(SEQUENCE(j,,1)*SEQUENCE(,i,1,0)), //Axis mode selection mode, IF(ISNUMBER(new_axis),new_axis, SWITCH(new_axis,"NE",1,"SE",2,"SW",3,1)), //Index selection x, CHOOSE(mode,x_NE,x_SE,x_SW), y, CHOOSE(mode,y_NE,y_SE,y_SW), //Unwrap indices and get results result, INDEX(array,x(),y()), result ) ))); //------------------------------------------------------------------------------------------- //ByDiagλ - Diagonal-based aggregation //------------------------------------------------------------------------------------------- //Apply an ETA function or Lambda to diagonals //Parameters: //array → 2D input array (scalars not accepted) //[function] → ETA function or Lambda applied to diagonals //[row_wise_stack?] → Optional: Display results as a vertical stack ByDiagλ = LAMBDA( array, [function], [row_wise_stack?], //Check array input ValidateDiagλ(array,,function,row_wise_stack?, LET( //Optional parameters No_Function, ISOMITTED(function), No_row_wise_stack,ISOMITTED(row_wise_stack?), //Dimensions i, ROWS(array), j, COLUMNS(array), //Diagonal count k, MIN(i,j), //Indices - deferred r, LAMBDA(SEQUENCE(k)*SEQUENCE(,j,1,0)), y, LAMBDA(SEQUENCE(k)+SEQUENCE(,j,0,1)), c, LAMBDA(IF(y()>j,NA(),y())), //Unwrap indices, shape, and aggregate result, IFNA(INDEX(array,r(),c()),""), shaped, IF(No_row_wise_stack,result,TRANSPOSE(result)), final, IF(No_Function,shaped, IF(No_row_wise_stack,BYCOL(shaped,function), BYROW(shaped,function))), final ))); //------------------------------------------------------------------------------------------- //DiagMapλ - Wrapper (Calls ByDiagλ) to extract diagonals as 2D matrix //------------------------------------------------------------------------------------------- //Calls ByDiagλ to extract the diagonals from a 2D array. //Parameters: *Please see ByDiagλ for descriptions.** DiagMapλ = LAMBDA( array, [row_wise_stack?], ByDiagλ(array,,row_wise_stack?) ); //------------------------------------------------------------------------------------------- //DiagIndexλ - Targeted diagonal extraction //------------------------------------------------------------------------------------------- //Extract a diagonal or anti-diagonal vector from a 2D array. //Parameters: //array → 2D input array (scalars not accepted) //col_index → Column number to start from.

Help Needed: Add Interactive Dashboard to Landowner Engagement Tracker (Same Sheet)
Hi all, I’ve built a basic Excel tracker to monitor engagement with landowners for a large infrastructure project. The purpose of the tracker is to: Show progress tracking of each case of for the project director to monitor progress help the Project Director Identify which cases may require statutory powers to secure access (if voluntary agreement isn’t possible) This helps our leadership team make informed decisions quickly. What I’ve got: A sheet called "LANDS RIGHT TRACKER" Columns include: Reference Number Agreement Status Case Status Risk Level (High/Medium/Low) Willingness to enter agreement Reason for refusal Flag for whether statutory powers may be needed 🛡️ All data is fictitious — names and details are placeholders, so no privacy concerns. What I need help with: my level of excel knowledge is very basic and I was hoping for some assistance to: Add an interactive dashboard and key metrics directly on the same sheet (not a separate worksheet). The below is just my suggestions as you are the expert your guidance expertise is much welcomed, happy for you to put it straight on to the tracker as I have left a section on the tracker for you to insert your items Ideally using a Pivot Table and Slicers to filter by: Case Status Risk Level Agreement Status Willingness to enter agreement https://docs.google.com/spreadsheets/d/1c2IJ-YLsTN-DZE9ltw0JR-nGVuuGzTKE/edit?usp=drivesdk&ouid=104511246399228274463&rtpof=true&sd=trueData Import issue???
I am working on a drift formula for items being pushed by wind and waves on the water. I imported a text file of weather data, formatted all the data to numbers, and built an "if" formula to convert the wind direction into drift direction. Wind from 360 degrees (north) would cause an item to drift 180 degrees (south). The problem is the formula sees everything as false. Is this a formatting issue with the imported text? =IF(B28<180,B28+180,B28-180)
How to create a Date-Time Temperature Graph
Hi there, I was wondering if Excel is able to create a similar Date Time vs Temperature graph as shown, the green coded one? (the data was extracted from an app) I want to be able to show the Date AND Time on my Excel chart I have the raw number data but is unable to convert it into a graph similar to the one shown above, for reference the format of my raw data looks like this (below), but my raw data have three thousands results. Thank you in advance to anyone who can help me! - Non
