Microsoft excel is known for decades to create spreadsheets. Since some years they provide an cloud version with Office 365 and soon newer Windows versions might only be usable by an Microsoft account. Not everyone likes to give their data to Microsoft. Besides Excel there are many other services from Microsoft, so when your Microsoft account is locked you can not access other services anymore. A Microsoft account locking happened by some people.
With Nostr as alternative you are using a protocol instead of a platform. You manage your account yourself by a cryptographic key. Keep your key secure well and you will always have access to your spreadsheets.
