What's the CSV format for Collections?
The best format for a CSV uploaded to Collections is a single column with no column header (column A only), encoded as UTF-8.

Only UTF-8 format is supported. Any other format will cause the upload to fail, including the Windows default in some older Excel versions.
Additional considerations
All columns aside from column A will be ignored.
Single empty rows will be ignored, but multiple consecutive empty rows will prevent any further content from uploading.
Large CSVs may take some time to import.
