Spreadsheet tips

  • Your file can keep its other columns. You’ll pick the phone column here, so there’s no need to edit the file first.
  • Keep phone numbers as text to preserve leading zeros.
  • Comma, semicolon, tab, and pipe separators, common CSV text encodings, and Windows, Mac, or Unix line endings are accepted.
  • Remove formulas and links from the phone column.
  • Excel files can be up to 25 MB (4 MB for older .xls files, which are converted on your device). For bigger lists, save as CSV (up to 1 GB).
  • Another file type, or a list stored in S3 or Google Drive? Contact us and we’ll import it for you.
