Spreadsheet blunders aren't just frustrating personal inconveniences. They can have serious consequences. And in the last few years alone, there have been a myriad of spreadsheet horror stories.
In August 2023, the Police Service of Northern Ireland apologized for a data leak of "monumental proportions" when a spreadsheet that contained statistics on the number of officers it had and their rank was shared online in response to a freedom of information request.
There was a second overlooked tab on the spreadsheet that contained the personal details of 10,000 serving police officers.
[...] In 2021, Crypto.com, an online provider of cryptocurrency, accidentally transferred $10.5 million (£8.3 million) instead of $100 into the account of an Australian customer due to an incorrect number being entered on a spreadsheet.
The clerk who processed the refund for the Australian customer had wrongly entered her bank account number in the refund field in a spreadsheet. It was seven months before the mistake was spotted. The recipient attempted to flee to Malaysia but was stopped at an Australian airport carrying a large amount of cash.
Industry studies show that 90 percent of spreadsheets containing more than 150 rows have at least one major mistake. This is understandable because spreadsheet errors are easy to make but difficult to spot. My own research has shown that inspecting the spreadsheet's code is the most effective way of debugging them, but this approach still only catches between 60 and 80 percent of all errors.
[...] To break the cycle of repeated spreadsheet errors, there are several things organisations can do. First, introducing standardization would help to minimize confusion and mistakes. For example, this would mean consistent formatting, naming conventions, and data structures across spreadsheets.
Second, improving training is crucial. Equipping users with the knowledge and skills to build robust and accurate spreadsheets could help them identify and avoid pitfalls.
Finally, fostering a culture of critical thinking toward spreadsheets is vital. This would mean encouraging users to continually question calculations, validate their data sources, and double-check their work.
