Big Brother at a Distance

We know that our spreadsheets should be functional and error free, but there is  a tension between how we review a spreadsheet to ensure that it is correct and the functionality of the spreadsheet itself. None of us like Big Brother breathing down our necks too closely.

In What is a Cell Map? I discussed the creation of a simplified version of a spreadsheet to aid review and error trapping. However, the map is itself a spreadsheet. If you created maps for each worksheet in your workbook, the workbook would quickly bloat and become unmanageable. The obvious answer is to post your maps somewhere else, but clearly linked to primary workbook.

The ACBA-Mapping package does just that. It generates a separate Map Book to hold all the spreadsheet maps (and other analyses) associated with the parent workbook. The parent workbook has a new worksheet that maintains a summary of all the detailed analyses generated for the workbook. This new worksheet is called 'DataList_and_MappingControl' and is, effectively, a reserved worksheet name.

A worksheet like this is added to the Parent Workbook
The 'Source' column lists analyses that have been applied to the whole book or an individual worksheet. Note that not all the worksheets are visible, but they will still be reviewed if you apply an analysis to the whole workbook. Most importantly this worksheet has a hyperlink, called 'Mapping Index', to the associated Map Book. Mapping Index refers to all the maps and other analyses you have created for the parent workbook.

Following the Mapping Index hyperlink opens the associated map book at its indexed worksheet.

The Index Sheet lists all the analyses that have been undertaken on the parent workbook.

Generating these Control Sheets

The ACBA-Mapping software is controlled through the Add-Ins menu.

Before mapping a worksheet (or any other analysis) the user must create the Control Records. This is an automatic process but can take a while for workbooks with several worksheets.

Access to the Software

The software package is available, without charge, from the link ACBA Mapping. If you need advice or have any queries please contact me at steveallen@netcom.co.uk

Spreadsheet errors and inconsistensies is a subject that is of concern by professional developers as well as amateurs. The European Spreadsheet Risk Interest Group (EuSpRIG) considers the problems from an academic and professional perspective.

The Blood Sugar Diet: A Control Approach

Here is a quote from ‘ Get the Gloss ’ , High blood sugar levels - millions of us have it, but many of us don’t know it and it’s led to not just a type 2 diabetes epidemic, but also a rise in  prediabetes , the condition that precedes it. Could calorie restriction help? It worked for medical journalist, Dr  Michael Mosley  and in his book,  The 8-Week Blood Sugar Diet , he shares the science behind it . This website offers a specific diet which, it seems, you should repeat for each day of the 8 weeks. That is one approach but I would get bored very quickly. I guess my likelihood of success under these circumstances would be small. My wife and I wanted controlled variety, but for that we needed to know the calorie content of a wide variety of foods and to measure them out for each meal. I also needed “proof” that I had adhered to the regime throughout the 8 weeks. Hopefully, it would demonstrate how I was moving away from the type 2 diabetes risk zone. Th...

What is a Cell Map?

It is a simplified, colour coded version of an Excel Worksheet. The map shows the structure of the worksheet, its input cells, constants, primary formula and 'named' ranges. The map is designed for spreadsheet developers who work in isolation (i.e. not part of a team), but who, nevertheless, build complex spreadsheet systems. It highlights oddities and inconsistencies within a spreadsheet structure. Excel has its own built-in auditing and mapping tools. Excel's name manager and formula auditing tools These are useful for auditing one formula or one name, but they become overburdened with detail when trying to audit/review a whole worksheet. The ACBA Mapping   [A revised version of the software is now available. Stephen Allen 05 September 2023] utility generates a map of the original spreadsheet and three map keys to aid the interpretation of the detail. For example, I went on strict weight reducing diet last year where I measured the weight/volume of everythin...

A Revised Cell Map!

  In the Blog ' What is a Cell Map? ', I included an image of a Cell Map. On reflection the presentation was muddled. A simpler and clearer design seemed worthwhile. The result below is more clearly rectangular, with the headings for the map, the formula table and the names/validation table matched along the same row. The validation table is new and highlights where user inputs are limited by validation and the nature of the validation criteria. The revised software is available at ACBA-Mapping . In addition, although software is intended to be intuitive and self explanatory, it rarely is. I have created a user group at    MSExcelCellMapping@groups.io   . You are welcome to join and ask questions about the software. https://drive.google.com/file/d/1w3tHk1l-G9LjmCsOqMBkJpE9kaSj0iX_/view?usp=sharing Spreadsheet errors and inconsistensies is a subject that is of concern by professional developers as well as amateurs.
