Excel Hazard #13: The Wayward Cell Block
|
Hazard Name: The Wayward Cell Block Description: An unintentional change in a block of formulas caused by accidental cut-n-paste, drag-n-drop, fill handle functions, or flash fill. Often results in a similar looking formula, but with the cell references being offset by one or more rows or columns. Detection: When resulting in an inconsistent formula in a row or block, these are usually flagged by a warning. They may also cause a #REF! error if at the ends of a row or column. Warning: Under certain conditions a block of errant cell formulas can be hidden and difficult to track down. Look for clues like repeating numbers, sudden changes in magnitude, or inconsistent formatting. If suspected, use tools such as Show Formulas (Ctrl+`) and Trace precedents/dependents (Ctrl+[ and Ctrl+] to navigate). Mitigation: Lock formula cells and protect worksheets.

I'm excited to be presenting at the 2025 SQA Annual Meeting next week - "Is it the Right Tool for the Job? How QA and Regulatory Professionals can Guide Software Decisions in Regulated Environments" As our familiar software tools become more feature-laden and generalized, it's critical to ensure that software meets clear use cases and basic user requirements. And with generative AI being shoehorned into every platform, defining if and how software is appropriate for the intended use has never...
Last time we left off with a cliff-hanger of a question: How do you prove you're you when signing a document? There are several ways I've seen that the 3rd party providers prove that it's you who's signed the document: You clicked a link from an email. You paid for the service with a credit card. You provided some government issued photo ID. Someone, such as a notorized public or your HR department, has verified it's you in person. Obviously these are very different levels of assurance. Then...
There are several levels of 'signatures' that you can apply to an electronic document. The first and most basic is just an image of your written signature. One common option for this is to print the document, sign and scan it back in again. A more convenient version is to have an image of your signature saved that you can paste into documents. This is what many free versions of pdf software and word processors offer as a basic document signing option - a 'stamp' of your saved signature image....
