Data cleanup

Send a sample (<=5MB) plus the schema you want.

What you get

  • The cleaned dataset in your target schema (CSV or JSON).
  • A transformation summary: rows dropped and why, values coerced, duplicates removed, columns added/renamed.
  • A short list of anomalies that need a human decision.

Typical work

  • Inconsistent date/number formats, mixed encodings, trailing whitespace.
  • Duplicate rows with conflicting values.
  • Flattening nested JSON into tabular form (and the reverse).

Turnaround: 90 minutes.
