How to automatically convert escape characters when reading json files

I am creating a process to output data that is linked in json format to a dataset.
I am currently implementing the following Python source,
The json file will be linked with control characters escaped,
I would like to output the escaped strings back to the control characters in the dataset with automatic replacement.

Please let me know if you know how to achieve this.
(The implementation has the following requirements)

▼Source

▼ Conditions
①Sync is used to get the json file.
②Output of dataset is done by CodeRepository.
③ Schema definition is not performed for the input dataset and the output dataset (automatic schema inference is also not performed).
④ The output dataset is output by replace.
⑤ We want to replace control characters for all items (items are variable, so it is difficult to specify).
