Feature Request

How do I set the save path? c:\aa\cell_formats.xlsx workbook.save("c:\aa\cell_formats.xlsx")?;

This is a general issue when working with Windows paths. The problem here is that \a and \c are control character in Rust/ASCII so you can't use them in a string.

error: unknown character escape: `a`

You can either use forward slashes:

   workbook.save("c:/aa/cell_formats.xlsx")?;

Or escape the escapes:

    workbook.save("c:\\aa\\cell_formats.xlsx")?;
