If that is avenue of integration seems too complex to setup, then there still might be other 3rd party integrations out there that could help. For example, it appears that Zoho has a means to integrate several different applications in this manner. See -servicedesk-plus-cloud/integrations/jira-cloud/ Disclaimer, I haven't tried to use this integration personally.
If you want to import Spiceworks data, what you could do is run reports export it into excel and those tickets can be imported into ServiceDesk Plus.Any other information you would need let me know or contact our support at sup...@servicedeskplus.com
