For Terraform plan files, `terraform show -json` will show a JSON representation
of the plan, configuration, and current state.
If you've updated providers which contain new schema versions since the state
was written, the state needs to be upgraded before it can be displayed with
`show -json`. If you are viewing a plan, it must be created without
`-refresh=false`. If you are viewing a state file, run `terraform refresh`
first.
The output format is covered in detail in [JSON Output Format](/docs/internals/json-format.html).
