### Optimization Notes.
1. **Remove Redundant Checks**: For `parse_multiple`, there's no longer a need to check if `'data'` is a list once more after it has initially been verified.
2. **Dictionary Comprehensions**: Used dictionary comprehensions within `_set_data` and `export_value` for faster data processing.
3. **Direct Access Methods**: Access dictionary values directly with `get` rather than checking attributes using `getattr`.
4. **Avoid Nested Imports**: The necessary class imports should be at the beginning of the file rather than within the method to avoid repeated import costs. However, this change depends on real usage scenarios and the environment configuration.

The structure and naming conventions remain unchanged for compatibility while focusing on internal optimization for operational efficiencies.
