Jetbrains? Use vim :)
Just kidding.
As for Excel, you can use LibreOffice calc, or OnlyOffice.
Or any office... or Excel web.
As for onedrive, i remeber linking my gdrive to my gnome files, but i personally don't need it that much, i use git lab/hub.
btw as for linking to phone, I recommend using KDE Connect.
