Thank you all for your help. I’ve found the thread pointing to the video describing how I can do it with JSON.
But there is another issue. It seems that when I export data with submissions where questions are split into groups, I cannot import them back. Let’s say I’m asking for an e-mail address in a group of questions called respondent. The column in the data table has “group_respondent / E_mail” in the header. I can see the same column when I export data into CSV and then I transfer them into JSON, the key “group_respondent/E_mail” is still there. Then, I use API to import that record back and it seems that the import normalizes the groups delimiter and there is a new column after the import called “group_respondent_E_mail”.
Is there any way how to solve this issue?
