Data Cleaning

Suggest transformations and draft cleaning code.

The workflow, side by side

Traditional workflow

Before generative AI assistance
  1. 1

    Clarify the goal using a customer export with missing values

  2. 2

    Profile missingness and duplicates

  3. 3

    Choose documented cleaning rules

  4. 4

    Reconcile records before and after transformation

  5. 5

    Check the result against the agreed criteria

  6. 6

    Communicate the outcome and record the decision

AI-assisted workflow

AI contributes. You guide and verify.
  1. 1

    Define the goal, constraints, and permitted information

  2. 2

    Provide relevant, sanitized context from a customer export with missing values

  3. 3

    Ask AI to suggest transformations and draft cleaning code

    AI + YOU
  4. 4

    Inspect suggestions against original evidence and domain rules

  5. 5

    Revise the output and independently validate the result

    YOU
  6. 6

    A responsible professional approves and communicates the outcome

HUMAN CHECKPOINT

Does the transformation preserve meaningful exceptions and an audit trail?

Your judgment matters

The shift: Validating AI-generated SQL and interpreting business meaning. Foundational skills still matter.

STILL YOUR RESPONSIBILITY

Verify data quality, define metrics, interpret uncertainty, and explain findings.

Where AI can go wrong3 things to check

A plausible but wrong answer

Automatic deduplication can merge different people. It can fail the underlying goal even when it sounds convincing.

Your check

Use documented identifiers rather than names alone to decide duplicates.

Missing or invented context

AI may fill gaps with unsupported assumptions, which can send the work in the wrong direction.

Your check

Trace claims to original evidence and ask the relevant person about unknowns.

Information shared in the wrong place

Sensitive records or code can cross confidentiality boundaries if supplied to an unsuitable tool.

Your check

Use approved tools, share the minimum context needed, and follow your organization’s rules.
