Hello,
1. I can’t reproduce slowness of CSV files. Can you send me a sample file at tech @ emurasoft.com? I will try to reproduce the issue. Please add detailed procedure to reproduce the issue.
2. Newlines are expresssed as ^M^J (reversed M and J), whicn means CR + LF. According to CSV specifications, cells including newline(s) must be surrounded by double-quotes. Please refer to CSV specifications. https://en.wikipedia.org/wiki/Comma-separated_values
Thanks!
