What File Formats Does Feedspace Accept for Customer Import?

Last updated on June 15, 2026

Accepted File Formats

When importing customers into Feedspace, you can upload files in these formats:

  • CSV (comma-separated values)
  • XLSX (Microsoft Excel, modern format)
  • XLS (Microsoft Excel, legacy format)

The maximum file size is 5 MB. Files larger than this will be rejected.

Required and Optional Columns

Your file must include at least the email column. All other columns are optional:

  • email (required)
  • name (optional)
  • phone (optional)
  • company (optional)
  • country (optional)
  • state (optional)
  • city (optional)
  • zipcode (optional)
  • date_added (optional)
  • tags (optional, separate multiple values with commas)

Column names must match exactly as shown above. Extra columns in your file are ignored.

Common Issues

My file is being rejected

Check that the file is one of the three accepted formats and is smaller than 5 MB. Files saved in other formats, such as ODS or Google Sheets (unless exported as CSV or XLSX), will not be accepted.

All rows are showing as skipped

If every row is skipped during import, the most common cause is a missing or incorrectly named email column. Make sure the column header is exactly email in lowercase.
