Find hidden cells and risky macros

Find hidden cells and risky macros

In version 12 of Rainbow we’ve added several new risk analysis options to the Risk Map function. We’ve done this by moving some “mapping” options from the last Risk Map tab across to the Logic Analysis function (see previous post). And we’ve also added an option to analyse any VB macro code in the workbook.

You can see from the screenshot above that the last Risk Map tab is now about “hidden” cells. These new options will reveal any attempts to hide sensitive cell contents by (for example) hiding a row or column, or applying a custom format such as “;;;”. And the “hidden operators” option will show up any double negatives (easily missed), plus the new implicit intersection operator “@”.

There are also new options on the other Risk Map tabs. These include an option to report any cells with “=SUM()” where the summed range includes subtotals, a very common cause of double-counting errors. You can also report where Excel’s own error checks have found issues, and the report on array formulas now includes the recently-introduced “dynamic arrays”.

The screenshot above also shows another new version 12 feature; a report on macro code issues. This checks for what are probably the two most common macro risk indicators:

  • Macros which run automatically when the workbook is opened; this is a technique regularly used in some types of malware.
  • Macros which have been created using Excel’s built-in macro recorder; this often results in macros which are liable to break or behave unpredictably.

So the Risk Map function in Rainbow version 12 is considerably more powerful than the previous version, and can make it much easier for you to find and correct potential problems in your spreadsheets!

Quickly undo changes with Rainbow 11.2

Quickly undo changes with Rainbow 11.2

Rainbow has offered an Undo Changes function for many years, and we made it much more visible in the recently redesigned menu (in version 11.0). However, as you probably know, it was only able to operate if you had already used the Save Format function to create a “format restore point” to which Rainbow could… Continue Reading

Fix merged cell problems with Rainbow 11.1

If you ask any professional Excel developer about merged cells, they will almost certainly say something that can’t be repeated here! Merged cells can produce incorrect calculation results, prevent sorting and filtering in data tables, cause errors in macros, and waste large amounts of time when spreadsheets have to be updated. Of course if your… Continue Reading

Find more hidden errors with Rainbow 10.1

Find more hidden errors with Rainbow 10.1

Rainbow has always been about finding hidden errors, and version 10.1 introduces a new analysis option (in Risk Map and Formula Scan) that detects error values lurking hidden in your IF() statements. A simple example would be where cells B3 and B4 contain the value 0, and B5 contains the formula “=IF(B3>0,B3/B4,0)”. In this case… Continue Reading
