Re-ordering spreadsheet
guywe Excel for the Mac, unfortunately, does not support the feature described by Martin_Weiss yet. But if you are an MS365 subscriber or have Excel 2021 you could use a LAMBDA function to unpivot the data for you. It's demonstrated in K3 in the attached file. I picked it up from PeterBartholomew1 no too long ago and tweaked it a little bit. Perhaps you can use it on your own data and create the reports you need from this tabular (unpivotted) data.
- Hi Riny, thanks. While the output of your spreadsheet is precisely what I'm seeking to achieve, Lamda functions are beyond my current capabilities! I will start off trying to use the Power Query functionality which is indeed available to mean my Mac as a MS365 subscriber. Appreciate your help - thank you!
guywe PQ is NOT available on the Mac to the extent that you need it. You can connect to a workbook or a TXT/CSV file and import them. That's it. No more PQ functionality, unless you dive into quite cumbersome VBA solutions. Nothing you would want to get involved with, I believe. And you don't really need to understand the LAMBDA. It works like a regular function. The only difference is that the "function" exists only in the workbook as a named formula.

Hi Riny
If you are getting involved with Lambda functions, would you like to see some utilities I have experimented with? One reads a data item from an arbitrary representation of a multidimensional array, using the Lambda function
= DATAλ(iᵣ)which takes as its argument an array of indices, iᵣ (in hindsight, I probably should have used separate parameters for each dimension but that would mean additional steps in the calculations).To be able to read a value back from any layout of data is useful, but I have also written functions that generate row and column arrays of such indices to allow the data to be repivoted (or aggregated by addition) at will. One option is to create a pivot-table normalised form of the users data.I have made a start with putting the Lambda functions up on GitHub as Gists but the process is completely alien to me (I have received some advice but I don't think my advisor realises the level of profound ignorance I can bring to the table).I have also attached the workbook that demo's the functions, though I would not claim to have got to the point of the workbook being self-evident.PeterBartholomew1 Will study with great interest!!
