GnuCash financial software

[RF]

Hello,

I just learned of GnuCash, being an exasperated Quicken Premiere 2014 
user and tired of being manipulated by their "sunset" expiration policy. 
I have just three main questions before trying GnuCash out:

1- Will it automatically update/download all my online financial account 
information from banks such as Wells Fargo, credit card accounts, 
Vanguard accounts and fundsand stocks of interest to follow?
2- If so is this feature free without expiration?
3- Can my existing .xls files be integrated with it such as a sync, so I 
can work on them from either end and not have to re-create them in a 
GnuCash specific format?

Thank you,
Bret
