Pandas to_csv，文件只能用 LibreOffice 读取

Question

I'm doing default Pandas read_excel, performing some actions on the dataframe, and at the end I'm saving the file:

df.to_csv(target, index=False, compression='gzip', sep='|')

although the file is readable only with LibreOffice Calc -UTF-8, USA. If file is opened with Excel then I can see the filename in the first row / first column, and bunch of diamons with question marks in the other fields. Tried to set encoding in 'to_csv' for 'utf-8', 'utf-8-sig', 'utf-16' but nothing seems to work. How to make this file readable in Excel also?

Thanks!

Compression was the issue here. Thanks!
