Spreadsheet export improvements

The Excel share is poorly designed. The whole point is to make it modifiable so a user can add something they would like or embed it to another document. To make it natural and easy to use, columns like duration, time, and mileage should be actual numbers properly formatted. Their relationship should be expressed in formulas, e.g., “arrival time” should be a sum of “departure time” + “charge time” + “drive time””
It would also be great (probably optionally when generating a spreadsheet) to have properly formatted and visually distinct measurements of full daily activities, such as total mileage, time spent charging and driving, average speed (and maybe additional derivatives)
Many people use Google Sheets instead of Excel, so a direct export will be helpful (now it could be done in 2 steps)
