Dangers of CSV Injection
Excel is the source of so many problems. At work, we ask users for an input in CSV or Excel format, and most people see &quot;CSV&quot; and export Excel data as CSV. Which is fine and great, but long numbers - such as UPCs - show up in Excel as scientific notation, being big scary numbers, <i>and also get exported as such</i>.<p>So when an Excel cell contains the UPC 123456123456, we get a CSV file that contains &quot;1.23456E+11&quot;, which is worse than useless.
