Excel formula

Job ID: 37783841

Budget: €8 – €30 EUR

I don't know if this is possible in a formula?

The Excel formula should do the following:

- Special characters of all kinds should be removed (?,ß,&,-,`,™,®, etc...)
- write everything in lower case
- Replace spaces with hyphens (-). But with ( - ), not (---) may appear but only (-)
- Change umlauts (Ä = Ae, ä=ae, etc...)
