Using Google Sheets formulas can occasionally result in unforeseen problems, particularly when working with data that is constantly changing. Unintentional expansion of a formula range is a frequent issue that leads to inaccurate computations. Because freshly added numbers outside the specified range might affect findings, this problem is especially annoying when collecting statistical data over time. Accuracy can be maintained by the use of named ranges, Google Apps Script, and structured formulas. Putting these methods into practice guarantees that your spreadsheet will continue to be dependable whether you're tracking business KPIs or handling financial reports.
