When Using Excel in One Drive Can I Hide Some Worksheets From Particular Users?

I have Office 365. I would like to save an Excel file to One Drive and share it with two associates.
I will call them User 1 and User 2. The spreadsheet contains financial data and I want to limit the access
each user has. More specifically, is it possible to specify that User 1 can only access worksheet "User1Stuff"
and User 2 can only access worksheet "User2Stuff"?

Here's another question. Can I prevent One Drive users from editing in the browser and force them
to download Excel to the desktop? If so, I could use VBA macros, which are not possible when editing in the browser.

Thank you!

Thank you for the information.

I'm sorry for the delay in replying. The workbooks have formulas that reference cells in the other workbooks, so I would need to have them all online for them to work properly.
I want to restrict a given user from seeing/editing certain workbooks.
Thanks for your help.
