Adding braces does not generate list

Hello, beginner here to mockaroo.

I’m trying to create a list of latitudes.

The field name is ‘lat’ and the type is Latitude.
To create an array, I replace the field name with ‘lat[5]’. This results in the values being empty when generating the data. What am I doing wrong? I’d appreciate any help.

Thanks

Previously the array notation only worked for JSON schemas. But as of this morning it works for all schemas. By default it will output as a json array. If you want just a comma delimited list, you can apply this inline formula to your field:

this.join(', ')
