    Spreadsheet Quality Checker — Local Browser Demo

    Self-directed demo by Methodarc Research. This is not client work.

    I designed and built a local-first browser tool that checks CSV and XLSX files for missing values, duplicate rows, mixed data types, and whitespace issues, then exports a structured issue list. Files stay in the browser instead of being uploaded to a third-party service.

    What the demo includes

    • CSV/XLSX import and sample-data mode
    • Missing-value, duplicate, type-consistency, and whitespace checks
    • Clear issue summaries and downloadable output
    • Responsive browser interface

    Verification completed

    • Five automated audit and XLSX tests passed
    • Server-render smoke test passed
    • Production build passed

    I can adapt the same workflow to a client’s agreed data rules, add validation checks, or package a lightweight reporting interface.
