OpenCodelists supports CSVs with header rows when creating codelists from CSVs

21 August 2025

On OpenCodelists, the “Create a codelist” form allows a codelist to be created by uploading a CSV file. Previously, every row of a CSV was treated as containing a codelist code. This meant any CSV header row had to be manually removed prior to upload.

An option is now available to select whether or not the CSV has a header row, removing the need for this manual editing.

Instructions for creating a codelist by uploading a CSV are at the documentation link below.
