Quote: "There’s no easy fix, either. Excel doesn’t offer the option to turn off this auto-formatting..." What kind of loopy Excel variant the article's author is using? It's right there in settings, you can easy stop auto-formatting. Yes, default installation has it on, but it can be turned off.
Create a simple CSV file like
Gene,value
SEPT1,-7
Open it in Excel, and watch SEPT1 be silently converted to 1-Sep, with no way to return.Exce is truly worse than most people can imagine.
