MF DataProof is a protected evaluation toolkit for legacy and mainframe data conversion, validation and reconciliation. It helps test COBOL copybook analysis, EBCDIC conversion, packed decimal / COMP-3 handling, CSV/JSON output generation and control-total validation. Built for technical assessment and modernization discussions, not licensed for production use without a commercial license.
I built MF DataProof after seeing how risky legacy and mainframe data migration projects can become when conversion results are not independently validated.
The goal is simple: provide a lightweight evaluation toolkit to test COBOL copybooks, EBCDIC files, packed decimal / COMP-3 values, CSV/JSON outputs and control totals.
This first public release is intentionally focused on technical evaluation: a downloadable protected package, local execution, sample conversion and reconciliation evidence.
I would really appreciate feedback from people working with legacy modernization, mainframe migration, COBOL systems, banking/insurance platforms, ETL or data reconciliation.
