The problem described here is not a glitch. It is a symptom of a spreadsheet tool that sees your data as a block of cells, not as a structured document with a meaningful hierarchy. When you sort 400 rows and your header row joins the party, the software is telling you it has no way of knowing that the first row is special. It treats your column labels as just another row of data. This is a fundamental limitation of traditional spreadsheets, and the frustration expressed by this user is completely valid.
For anyone managing a daily log, a growing inventory, or any dataset where headers are the anchor, this is a practical crisis. You lose the label that tells you what column is "Date," "Amount," or "Item." Suddenly, your sorted list is meaningless. The user tried freezing panes, restarting the program, and restarting the PC. None of those work because they address the symptom, not the root cause. The real fix is to define the header row explicitly. In a traditional tool, this means using a "Create Table" or "Format as Table" command, which locks the header in place during sorting. Without that step, the software treats the header as a data point, and a sort will always scramble it.
This moment, where a simple action breaks a trusted workflow, is exactly where AI-native tools offer a different path. An intelligent spreadsheet does not need you to remember to "Format as Table" before sorting. It understands structure from context. It recognizes that the first row contains labels, not values. It can sort 400 rows, or 4,000, without ever touching the header. The solution is not to find a hidden checkbox or a workaround macro. The solution is to use a tool that treats your headers as the permanent, inviolable guideposts they are meant to be. If you are spending time fighting your software over a basic sort, it is time to ask whether the tool is working for you, or if you are still working for the tool.
