# CSV cleaning sample

This is a demonstration sample, not proof of customer work or a customer outcome. It must not be presented as a real customer catalogue, supplier file, testimonial, or completed paid engagement.

It shows a bounded cleanup of an original, deliberately messy CSV.

- Simulated issues: whitespace, one duplicate SKU, and formula-like text.
- Actual public data used: product names only.
- The names derive from public-domain USDA data. The SKUs, packs, prices, notes, deliberate errors, and outputs are synthetic.
- No values were inferred. Leading zeros and decimal text were preserved.
- The leading apostrophe in the cleaned formula-like field prevents spreadsheet formula execution.
