Here's a function to rename the key:

yyjson/src/yyjson.h

Lines 3765 to 3791 in 82ea883

 /** Replaces all matching keys with the new key. 

  Returns true if at least one key was renamed. 

  The `key` and `new_key` should be a null-terminated UTF-8 string. 

  The `new_key` is copied and held by doc. 

  @warning This function takes a linear search time. 

  If `new_key` already exists, it will cause duplicate keys. 

  */ 

 yyjson_api_inline bool yyjson_mut_obj_rename_key(yyjson_mut_doc *doc, 

 yyjson_mut_val *obj, 

 const char *key, 

 const char *new_key); 

 /** Replaces all matching keys with the new key. 

  Returns true if at least one key was renamed. 

  The `key` and `new_key` should be a UTF-8 string, 

  null-terminator is not required. The `new_key` is copied and held by doc. 

  @warning This function takes a linear search time. 

  If `new_key` already exists, it will cause duplicate keys. 

  */ 

 yyjson_api_inline bool yyjson_mut_obj_rename_keyn(yyjson_mut_doc *doc, 

 yyjson_mut_val *obj, 

 const char *key, 

 size_t len, 

 const char *new_key, 

 size_t new_len);

from yyjson.
