I can see no snort definitions here, only a listing - a Snort rule looks like this:
<Action> <Protocol> <Source IP Address> <Source Port> <Direction>
<Destination IP Address> <Destination Port> (msg:"<Text>";
<Keyword>:"<Option>";)
But you only have a list of threats and signatures, not snort definitions/signatures itself, with the columns:
Threat ID
Threat Name
Severity
Release Date
Signature ID
Signature Name
It is not possible to convert this into snort rules...
