I help businesses turn inconsistent data into reliable, usable information. I work with Excel, Access, CSV, fixed-length files, and database sources to identify data-quality problems and develop practical validation and reconciliation workflows.

Depending on your needs, the work can include: • Mapping fields and standardizing formats across sources • Identifying duplicates, missing records, and invalid values • Comparing datasets or reporting periods and investigating discrepancies • Applying agreed business rules and tolerance checks • Producing exception reports and preparing downstream exports • Automating repeatable processing where appropriate

Deliverables are agreed before work begins and may include validated output files, reconciliation reports, reusable processing tools, and documentation explaining the rules and remaining exceptions.

Please contact me with your source formats, approximate data volume, and expected results so we can define the scope, timeline, and price. Other services I offer:
