Hi,
I use Excel 2013 to manipulate CSV files. I experienced issue with number format cells. In my CSV file there is one column that presents latitude values in format: 52.05456464. When I open my CSV file in Excel 2013 all values in that column get separator".", in this case my number is present like this: 52.054.454.464. I tried to change my cell format, and when opened the category was Number, I change it to the General but in that case I lost all "." and got 52054454464.
I also tried to open same file on other machine with Excel 2010 and file is opened correctly without issues and in cell format the category is general by default.
I hope that there is some kind of resolution for this.
