How to duplicate a CMS collection on the same website in Webflow?

TL;DR
  • Export the Collection: Download the CSV from the CMS Collections panel.
  • Create a New Collection: Manually recreate the fields in a new CMS collection.
  • Modify CSV: Remove the "ID" column and adjust multi-reference/image fields.
  • Import Data: Upload the CSV and map fields carefully.
  • Manually Add Missing Data: Reassign multi-reference and image fields manually.

Duplicating a CMS Collection in Webflow isn’t a built-in feature, but you can manually recreate it by following these steps.

1. Export the Existing Collection

  • Go to CMS Collections in the Webflow Designer.
  • Select the Collection you want to duplicate.
  • Click the Export button (top right).
  • Download the CSV file when prompted.

2. Create a New CMS Collection

  • Click Add Collection and name the new collection.
  • Recreate the Collection Fields from the old collection. Webflow’s CSV import can’t auto-create fields.

3. Modify the CSV for Import

  • Open the CSV file in Excel or Google Sheets.
  • Remove the "ID" column (Webflow does not allow importing IDs).
  • Adjust any multi-reference or image fields (you’ll need to manually re-add these later after import).
  • Save the file as CSV format.

4. Import Data into the New Collection

  • In Webflow, open the new CMS Collection and click Import.
  • Upload the modified CSV file.
  • Map the fields carefully to match the new collection fields.
  • Click Import Items and wait for Webflow to process the data.

5. Manually Add Multi-Reference & Image Fields

  • Webflow cannot import Multi-Reference or Image fields via CSV.
  • Open each collection item and manually reassign any missing references or images.

Summary

Since Webflow doesn’t offer a one-click CMS collection duplication feature, you must export the existing collection, recreate it manually, and import the data via CSV. Multi-reference and image fields must be updated manually after import.
