What is this data format?

I am working with json data from an external source and for some reason they encoded additional data in a string field instead of putting it in separate fields. Is this the next standard? I've never seen it and I need to sort it out somehow. Json looks like this:

{
    "description": "Description text here. \n #1621R5N9-{:organization/name \"Redacted Co.\", :organization/logo \"http://www.example.com/logo_redacted.png\", :organization/id 23, :organization/website \"http://example.com\", :organization/office []}-16722"
}
