In order to upload contacts into your account, we require that you first save your spreadsheet as a CSV (comma separated values) file. A CSV file stores tabular data in plain text and is saved with a .csv extension. While a CSV file may look similar to an Excel file or Google Sheet, CSVs cannot save styling, formulas, or multiple sheets.
