Hi, I have tried to do a trial export in csv. It seems that the responses to custom fields are not exported.
Is there a way to do that?
Hi Peter,
Welcome to the Community! 
All custom field data should be included when exporting subscriber data.
It’s best to double check you’re on the correct list when exporting your data just in case you’re exporting from a list that does not contain the custom fields you’re looking for.
I also suggest exporting your subscriber information again using another browser to see if the file exports correctly, as it’s possible this may be due to a cache or cookies related issue in your current browser.
If you experience any continued issues, please let us know.
