The CSV plugin turns CSV files you prepare into JSON files the Importer can load. Use it to import members from another system, a list of email addresses, or test data.
You need to know the The JSON File Format: each CSV column becomes a key in the JSON.
The plugin comes with a sample: modules/jrExporter/plugins/CSV/samples/sample_members.csv. Its columns are:
profile_name, user_name, user_email, _profile_export_id, _user_export_id,
_profile_created, _profile_updated, _user_created, _user_updated,
profile_quota_id, profile_private, user_password, _profile_file.image, _user_file.imageEach row is one member. The _profile_file.image and _user_file.image columns are addresses of images to download.
csv.On Create JSON Files, choose the files in Export Selected Files, and start. Check the result with Tools > Review Created JSONs before you import.
