TUDF / CDSF Converter

When credit data exported from your existing loan system does not match the target platform's format requirements, it must be restructured, field-mapped or converted, and your business has to spend extra IT resources on data reconciliation and testing.

Cash Direct's TUDF / CDSF converter transforms your internal credit files into the CDS-compliant CDSF (Credit Data Submission Format) seamlessly. It runs entirely within your intranet: no data leakage, no external hosting, aligned with the Personal Data (Privacy) Ordinance.

Customer Challenges

Exportable Data Is Not Always Usable Data

Credit data must follow specified formats and data requirements. When your system's output differs from the target platform's requirements, extra work is needed for data preparation, field mapping, format conversion and validation.

Challenge 1

Inconsistent output formats across systems

Different systems may use different field names, data structures, formats or export methods, so credit data cannot always be used directly in the target workflow.

How Cash Direct Helps

We assess the gap between your current and target formats, clarifying the required field mapping, format handling and conversion rules.

Challenge 2

Repeated data preparation and conversion

When data does not fit the target format, staff or IT teams may need to clean files, adjust fields and fix format issues repeatedly.

How Cash Direct Helps

Based on confirmed specifications, we evaluate a suitable conversion approach to reduce unnecessary manual work. Actual automation depends on product capabilities and project requirements.

Challenge 3

Format errors increase checking and troubleshooting

Incorrect field mapping, missing mandatory data or non-compliant formats can all require data to be re-checked and reprocessed.

How Cash Direct Helps

We assess validation and error-handling needs against the relevant specifications, clarifying fields, format rules and exceptions to check.

Challenge 4

Every data run depends on IT staff

Without clear rules or suitable tools, daily processing may rely on IT teams for manual handling, affecting other maintenance and development work.

How Cash Direct Helps

We review your current data handling and assess the feasibility of conversion tools and workflow integration, so you know exactly what to improve.

Challenge 5

Hard to confirm converted data meets requirements

Completing a conversion does not mean the content and structure fully meet the target platform's requirements. Results, completeness and validation conditions still need confirmation.

How Cash Direct Helps

We help define post-conversion validation methods, test scenarios and acceptance criteria. Actual validation rules and scope are subject to the relevant specifications.

Beyond Conversion: Verify the Result

01

Supported Formats & Versions

Confirm the actual source formats, target formats, versions and conversion directions supported, rather than judging compatibility by product name alone.

Field Mapping & Conversion Rules

Understand support for required field mapping, data type handling and conversion rules, and how unmappable data is handled.

03

Validation & Exception Handling

Confirm whether the product checks format issues, mandatory and missing data, and provides error messages or reports.

04

Import, Export & System Integration

Confirm how daily data enters the converter, how results are exported, and whether integration with your loan system or other platforms is needed.

05

Data Security & Access Control

Review data processing, access rights, transmission and storage arrangements, and record management against your security requirements.

06

Testing, Maintenance & Format Updates

Confirm how specification changes are handled, who is responsible for updates, and what testing, maintenance or technical support is provided.
