AI Tools for Data Cleaning and Enrichment
Garbage in, garbage out. AI models, automations, and dashboards are only as good as the data they run on. Data cleaning is unglamorous but it's the highest-leverage work before any AI initiative.

Prompts to get started
Audit a dataset for quality issues
Paste a sample of your data and get a structured quality assessment with specific issues and fixes.
Please audit this dataset for data quality issues. [PASTE A SAMPLE OF YOUR DATA — first 20-30 rows with headers] Context: This data is used for [describe what you do with it]. Please identify: 1. Missing or null values (which columns, how many rows affected) 2. Formatting inconsistencies (e.g. mixed date formats, case inconsistencies) 3. Duplicate records or near-duplicates 4. Outliers or values that seem wrong 5. Fields that are ambiguous or undefined For each issue: give the specific problem and the recommended fix.
Design a data governance policy
Define rules for how data is collected, stored, and maintained.
Write a data governance policy. Org size: [employees] Data types: [customer PII / financial / employee / analytics] Regulatory requirements: [GDPR / CCPA / HIPAA / SOC 2] Current problems: [duplicates / inconsistent formats / unclear ownership] Tools: [CRM, database, warehouse, BI tool] Policy covering: 1. Data ownership: who is responsible for which datasets 2. Quality standards: what 'good' data looks like 3. Data entry rules: formats, required fields, naming conventions 4. Retention: how long to keep each data type 5. Access controls: who can see and edit what 6. Cleaning cadence: how often to audit 7. How to handle a data quality issue
Write a data enrichment brief
A clear brief gets better results from enrichment vendors.
Write a data enrichment brief. What we're enriching: [contacts / companies / transactions] Current fields: [list what we have] Fields we need: [list what we want — size, industry, LinkedIn, revenue, tech stack] Use case: [lead scoring / personalisation / segmentation] Quality requirements: [accuracy threshold, handling missing data] Vendor: [Clay / Clearbit / ZoomInfo / Apollo] Volume: [number of records] Brief covering: 1. Input format and fields 2. Output requirements with definitions 3. Quality and coverage expectations 4. How to handle records where data can't be found 5. Delivery format and timeline
Write data transformation rules for messy data
Define rules to make inconsistent data consistent.
Write transformation rules to standardise this data. Data type: [company names / job titles / phone numbers / countries / addresses] Sample of inconsistent data: [PASTE 15-20 examples showing the variation] Desired output format: [describe the clean version] Platform: [SQL / Excel / Python / Zapier / Clay / Airtable] Please: 1. Identify all variation patterns in the sample 2. Write transformation rules to standardise them 3. Provide the logic in plain English 4. Provide code or formula for my platform if applicable 5. Flag edge cases that need manual review
