```python
# Your code here, if applicable

I have values in my tables as 5-7, 3-5, 5-6, these values are converting into date formats like 07-May, 05-Mar, 06-May. But those values are related to length, width and height, so i want to leave the values the way it is and to convert into date format only to date values. This is happening only when saving the data in 'to_csv' method and working properly in 'to_excel' method.

Also hyphen(—) values in csv are converted to â€” and working properly in excel.

Any help in any of the issues are much appreciated.

Thanks.
