CSV dataset change detection: a practical checklist

A focused checklist for teams that repeatedly download a public CSV and need to know what changed between versions.

  1. Keep the authoritative download URL and a dated copy of the current file.
  2. Record column names, types and the key fields that identify records.
  3. Compare later versions for added, removed or renamed columns.
  4. Separate structural changes from ordinary row-value updates.
  5. Keep the before/after evidence for material changes that affect downstream analysis.
