I am completely new to bitcoin. My question is how do you convert an uncompressed key to an extended bip32 key? Are there any tools that do that? Thank you

With "uncompressed key" you probably refers to an uncompressed public-key.
An extended public-key has additional informations (next to the compressed public-key itself). You can get the pure compressed public key from an extended public key, but not vice-versa.
depth(in the hierarchy)child-indexchaincode(the hierarchal link)fingerprint(first 4 bytes of the keyId [ripemd(sha256())])
They have different use cases. A public key is for receiving sending on, an extended key is for deriving more keys from. Why do you need to convert one into the other, as opposed to creating a new one, for example? – Pieter Wuille – 2016-11-07T17:29:16.027
