In order to upload subscribers into your Automizy account, we require that you first save your spreadsheet as a CSV (comma separated values) file.
A CSV file is saved with a .csv extension and stores tabular data in plain text.
It may look similar to Google Sheet or an Excel file, however CSVs cannot save styling, formulas, or multiple sheets.
Use UTF-8 encoding for saving the CSV.
