I turned my offline CSV cleaner into a $19 done-for-you cleanup service

After launching CSV Cleanroom, I learned that some people do not want another tool—they want one recurring export fixed and documented.

I am testing a small, privacy-first service: send the headers and 5–10 anonymized rows from one CSV structure, plus the problem you want eliminated. I will return a cleaned example, exact header mappings, validation and deduplication rules, and a short quality report. One revision is included.

The scope is deliberately narrow: one structure, up to 30 columns, with no confidential or identifying data. Delivery is within 3 days and the price is $19 once.

If you handle recurring exports from a CRM, payment tool, survey platform, or operations system, which cleanup rule wastes the most time for you?
