CSV Data Compare
Compare two CSV files using one or more business keys and pinpoint missing records, duplicates and column-level differences.
Focused software for the problems that generic tools don't solve well — with simple, powerful AI built into the workflow.
No generic chatbot. Give AI the actual result, file issue or comparison — then ask it to explain, diagnose or act.
We don't chase the crowded “convert anything” market. We build utilities for annoying, expensive, time-consuming work.
