Save an Excel spreadsheet as a CSV file

Updated: April 1, 2023

Convert an Excel spreadsheet into a Comma Separated Value file to import large lists or reduce the chance of import errors when uploading contacts

If have more than 40,000 contacts, or you're running into errors while trying to import your contact list into Constant Contact, it can help to check the formatting and then save your Excel spreadsheet (XLS, XLSX) as a Comma Separated Value file (CSV) instead. CSV files are just like Excel spreadsheets, except they strip out the excess formatting that causes some import errors.

Light Bulb IconDid you know? When importing into Constant Contact, CSV files can accommodate up to a million rows of contacts or up to 100 MB of data if your account is enabled. Excel spreadsheets and TXT files can accommodate up to 40,000 rows of contacts, or up to 2MB of data.
 
  1. In your Excel spreadsheet, click File.

  5. Click Save.

When you open your CSV file, it will look just like the Excel spreadsheet, except any excess formatting will be removed. Now that you've saved your Excel file as a CSV, import your contact list into Constant Contact. For help with older versions of Excel, please see Microsoft Office Support.
