The invention relates to a mind map processing method and device, computer equipment and a storage medium. The method comprises the following steps of obtaining tree structure data formed by the cachemind map; respectively converting each node in the tree structure data into a JSON object, enabling jSON objects obtained through conversion of nodes of the same type to form a JSON array, mounting the JSON array to the JSON objects obtained through conversion of father nodes of the nodes of the same type, and acquiring a node content file in a JSON formatand generating a mind map file accordingto the node content file. By adopting the method, the size of the mind map file can be effectively reduced.
