Column mapping tells Landing Zone which spreadsheet column feeds each contact field. Map once, save the mapping as a profile, and reuse it every time the same file layout comes back.

Before you start

  • A CSV or XLSX file uploaded on the Import page — see Import a CSV.
  • Headers in the first row of the file, one per column.

Steps

  1. Upload your file on the Import page. The mapping step opens with a sample preview of your data.
  2. Match each column to a Landing Zone field. Work through the columns and pick the field each one should fill.
  3. Complete every required field. The mapping screen labels which fields are required — map those before moving on.
  4. Check the sample preview against your mapping. Confirm names, phones, and emails land in the right fields before you continue.
  5. Save the mapping as a profile. A saved profile applies the same mapping to future imports with the same layout.
  6. Manage profiles over time. You can create, duplicate, update, and delete mapping profiles — duplicate one to make a variant for a slightly different file layout.
  7. Finish the import. Continue to the opt-in acknowledgment and run the import — see Import a CSV.

Tips for messy headers

Clean the file before you map

Limitations

  • The import can't proceed until the fields labeled required are mapped.
  • A mapping profile matches a specific file layout. If your headers change, update the profile or duplicate it for the new layout.
  • Mapping doesn't clean data. Invalid values still cause rows to be dropped at import — counted and reported. See Resolve import errors.

Frequently asked questions

Do I have to remap every import?

No. Save the mapping as a profile and reuse it whenever the same file layout comes back.

My header names change from file to file — what should I do?

Standardize the headers in your spreadsheet template if you can. Otherwise keep one mapping profile per layout — duplicating an existing profile is the fastest way to make a variant.
