superset export-dashboard -f

The command `superset export-dashboard -f` is used to export a dashboard in Superset and save it as a file. The `-f` flag specifies the format in which the dashboard should be exported.

Here's an example command to export a dashboard in JSON format:

superset export-dashboard -f json --dashboard-id <dashboard_id> --path <output_path>

Replace `<dashboard_id>` with the ID of the dashboard you want to export, and `<output_path>` with the desired file path where you want to save the exported dashboard JSON file.

This command will export the dashboard metadata, including charts, slices, and associated information, into a JSON file. You can specify other formats such as YAML or CSV by changing the value of the `-f` flag accordingly.
