Learn to clean a messy dataset by prompting a generative AI chatbot to remove duplicates, filter null values, fix formats and split columns.
Messy data stalls analysis before it begins. Repeated rows, empty fields and values written several different ways can leave a dataset unusable. In this project a generative AI chatbot acts as the cleaning assistant. You learn to phrase prompts that get it to spot what needs fixing and then carry out each repair, so a raw table ends up in a state you can actually analyze.
What You Will Achieve
- Ask a generative AI chatbot to list the cleaning steps a messy dataset needs
- Write prompts that get the chatbot to drop repeated records and rows with missing entries
- Use prompt engineering to make inconsistent formatting uniform across a dataset
- Turn one combined column into separate, usable fields by instructing the AI
Program Overview
Planning Data Cleaning with Prompts
Starts by having the chatbot look over a messy dataset and identify the cleaning steps it needs.
- Prompting a chatbot to assess a dataset
- Choosing the cleaning steps to carry out
Removing Duplicate and Null Values
Uses targeted prompts to clear out repeated entries and rows with null values.
- Spotting and removing duplicate records
- Filtering out rows with null values
Standardizing Formats and Splitting Columns
Reshapes the remaining data so values follow one format and each field sits in its own column.
- Making inconsistent formatting uniform
- Splitting one column into usable fields
Certificate Awarded (Paid)
Job Outlook
Data cleaning is routine work in data analytics and reporting, and in any role that prepares spreadsheets or datasets for analysis, especially when a quick result is needed without writing code.
Good for: Newcomers to data analytics who keep running into messy datasets and want a chatbot to guide them through routine cleaning tasks.
Keep in mind: The cleaning happens through prompts to ChatGPT rather than code, so pandas and SQL cleaning functions are not part of the project.
Bottom line: A focused one-chapter project in which planning the cleanup and four common fixes are each done by prompting an AI chatbot.
Frequently Asked Questions
Does the project involve writing any Python code?
No. Each cleaning task is handled by writing prompts for ChatGPT, and the chatbot carries out the steps, so the work stays in plain language throughout the project.
How does prompting compare with cleaning data in pandas or SQL?
Rather than learning library or query functions, you practice guiding a generative AI model through common cleaning jobs. That approach is handy when you need a quick result and would rather not write code.
Which AI tool does the project use?
The project works with a chatbot built to walk you through cleaning a dataset, and the prompts are written for ChatGPT. The emphasis is on prompt engineering: shaping each request so the chatbot's answers move the cleaning forward.
