I like to use the plain-size data as a text swatch in the size attribute.
This size data is available in the admin fields. We have too many articles to enter the swatch data manually.
I know there are some similar questions and answers. Those answers are based on unique codes and scripts. [ I have little knowledge or experience in that ] I wonder, are there other options?
- Option check marks like "Use size data as swatch data"
- Import a CSV, linking size data to text swatch data
- Leaving a comparison table in some folder
