The formats with 'x' at the end are actually zip archives, so any more compression is moot. You could unzip the Excel sheet and look for data based compression.
- Images in lower resolution.
- Excel XML with less repetition of styles, attributes.
- Repeated expressions.
- Maybe there are embedded fonts.
