Warning is raised when converting css styling fails.

This can be due to the styling not having an equivalent value or because the styling isn’t properly formatted.

... # CSSWarning: Unhandled color format: 'blueGreenRed'
>>> df.style.applymap(lambda x: 'border: 1px solid red red;')
...         .to_excel('styled.xlsx')
