Hi Richard, thanks for posting! I saw you replied to another thread with this question and I responded to you there. Re-posting my response below for extra visibility.

Unfortunately the ContainedBy field you see in the CSV export currently isn’t included by default in the JSON response to a GET Document Contents, so there is no way to tell which shapes are in containers.

However, one way you could work around this is by using the CONTAINED or CONTAINEDBY formula functions in your document. This would allow you to identify which shapes are in which containers from the "customData" part of the JSON response. You can find an example in this Developer Community post, where another user is seeking help with the exact CONTAINED function to use.  

Please feel free to respond with your feedback or a brief description of your use case, especially if this workaround isn’t suitable. We are always looking for ways to improve our public API’s and we value your feedback. 

Thank you, I’ll have a look at that option.  I would happily use a CSV export too if there were a way to download that via API.  I had hoped changing the accepted format to text/csv would have worked.

I have the same issue and would also happy if CSV export over REST API is possible or even better, if the contained by info is included in the JSON reply. 

Hello ralfpanse,

I apologize for the very delayed response. I had taken note of this request for internal discussion but failed to respond.

As mentioned, we don’t currently offer an API based `CSV export`, nor `containedBy` within JSON. However, I have passed these requests on for internal consideration. For clarity, these changes would not be available soon, but the feedback is helpful in us understanding what improvements would have the most value.

Hello Michael,

Lucid is great to collaborate live with team members. Nevertheless, sometimes there are a lot of information on the board which have to be processed or transformed into Jira Issues, Confluence pages, other Lucid Boards, … . 

One important information is to know, on which swimlane a sticky note is located in. For example, 

a team member has a new idea of the category “Cost Saving”. “Cost Saving” is represented in a swin lane. After colaboration with Lucid the data will be shift into workpackes in Trello or Jira. Therefore, not only the sticky content is important. Also, the underlaying swin lane or other container is a necessary information. 

Hello ralfpanse,

I completely agree. Containers are an important tool for visualizing and categorizing information on a board. The functionality to export a board’s contents is very hamstrung by not having contained (and other aspects of a board’s contents).  Hopefully, we will be able to expand the functionality in the future to make it more usable.
