CMS: Changing a Field Type in a Collection

Lord Of The Wix · Oct 25, 2026

Change the type of data you can store in a CMS (Content Management System) collection field by changing the field type. Keep in mind that changing the field type of a field that is connected to page elements can disconnect the elements on your live site.


Important:


You cannot change the field type for 'Primary' fields, 'System' fields, 'Digital asset' fields' or fields in collections that are added to the translation manager in Wix Multilingual.


Effects of changing a field type


Consider the effects of changing a field type to ensure your live site content remains connected and functioning as expected. Since field types determine the type of data you can keep in each field, changing them can disconnect any of their connected page elements. This can result in page elements displaying no content at all or not working as expected.


Other problems that can occur as a result of changing a field type:



In your collection, if you have fields with values that do not match the field type, a Warning icon

appears to let you know. If available, you can click to convert the value so it matches the correct field type format.

Can I choose field types when importing a CSV file to a collection?

Yes. During the import process, you can choose the field type used for each field you import.

By default, when you import a CSV file to your collection, the first row in your file is used as the field names and the field types are automatically detected. You can choose which columns from your file you want to import as fields. For each column you import, you decide whether to create a new field or match it to an existing collection field. You can also change the field name and field type that are automatically configured.

If you import data to a field that does not match the field type, a warning message will appear in the relevant collection fields in the CMS. You can change the field type for the entire column in your collection or, if available, convert the data in each field to the relevant field type.
