Hi! How do I find the person changing Card names of members on Trello

[Fahad Masood]

We have a Trello board for our company and I have found someone is changing card names of Trello Board I tried to find that person on Trello but couldn't reach him 

Is there any way to find out that person?

The JSON export of that specific card will allow you to retrieve the previous descriptions as well as seeing which user actually made the change.

The change of the title will be recorded as "actions: [" and contain the old as well as nnew description and the user that changed the title.
