That single text field is treated like CSV data. It parses each row into placeholders such as %%csv_field0%% for the title, %%csv_field1%% for keywords, %%csv_field2%%, %%csv_field3%%, %%csv_field4%% and so on for your custom fields. There's no separate upload button or file‑based CSV parsing. You're not uploading a .csv file per se, you're pasting structured text (Ctrl+C/Ctrl+V), and the plugin handles it exactly the same.

So when the docs mention CSV formatting or using CSV placeholders, they're referring to formatting data in that one field. If you want to use CSV data, paste your pipe‑delimited rows into "Article titles" and the plugin will make custom data available via %%csv_fieldN%%.
