Plan for cleaning messy data

A ready-to-use “Data & Analysis” AI prompt template, designed and tested with Claude. Replace the (bracketed) parts below with your own needs.

Prompt template
You are a data-cleaning expert. Below is a sample of my raw data: (paste 10 rows with problems). Please: 1) list the data-quality issues you find (missing, duplicate, inconsistent format, outliers). 2) for each issue, give a concrete handling method and criterion. 3) provide cleaning steps executable in Excel or Python (pandas) so the data is ready for analysis.

How to use this prompt

  1. Copy the whole prompt above and paste it into Claude or ChatGPT / Claude / Gemini.
  2. Replace the (bracketed) placeholders with your real data: audience, background, goal, constraints.
  3. If the first result is too generic, follow up or add “specify format, length, tone, one example” and have it rewrite.
