Importing CSV with line breaks in Excel 2007

Question

I\'m working on a feature to export search results to a CSV file to be opened in Excel. One of the fields is a free-text field, which may contain line breaks, commas, quota

Answer 1

I have finally found the problem!

It turns out that we were writing the file using Unicode encoding, rather than ASCII or UTF-8. Changing the encoding on the FileStream seems to solve the problem.

Thanks everyone for all your suggestions!
