CSV needing a password.

I'm downloading a CSV file and some of the contents have locked cells and needs a password. What is it?

A CSV file, by nature, is just some text with commas separating it (C-Comma S-Separated V-Value). It's a really simple file, and that's one reason why it's so widely used for transferring information in and out of different software. The CSV file, to my knowledge, can't have anything like that associated with it. Based on that logic, I'd say something local is going on, something on your computer. Have you tried a different computer?
