I am downloading Jira details into Excel using power query. I am struggling to get all the fields.

I have no idea how to specify all the fields that I want.  Is there a way to request all fields?

Currently using "fields=summary,description,benefit".  I need more though.  I have a filter that specifies the fields.  Can I use this filter in the JQL and then request all fields somehow?
