Dear Amy Babinchak,
Good day! Thank you for posting in Microsoft Community.
As per your description, you are using JSON code to make a multi-line text field in Microsoft Lists editable without having to open it.
We'd love to help you, considering we mainly focus on general and build-in features' troubleshooting in SharePoint Online, we're afraid we have limited resource about JSON code queries.
At the same time, considering we have a dedicated channel Microsoft Q&A Community - SharePoint, for you to be assisted properly, we sincerely recommend you go to that community and post a new thread, members and engineers over there are proficient in the knowledge of SharePoint customization and development queries. They will focus on the specific situation on your side and share specific suggestions. We are sure that our experts from that team can address your query effectively and accurately.
Thanks for your cooperation and understanding. Hope you keep safe and healthy always!
Sincerely,
Tina | Microsoft Community Moderator
