How to use ChatGPT for data cleaning

Survey data is a cornerstone of many business decisions and research projects.

However, poor data quality can impact those outcomes.

We hear all of the time about survey data:

- Missing values
- Having Inconsistencies
- Having duplicates
- Including bots
- Including respondents who have rushed through questions.

All of which can lead to flawed strategies.

This is why I took ChatGPT for a test.

To see if it could help clean survey data.

Let’s dive in.

Before I do, you can follow a long using the video and step by step guide below:

ChatGPT as a solution for market researchers

Step 1: Preparing the data

First, ensure your survey data is collected and formatted in a machine-readable format, such as a CSV or Excel file.

This preparation step is crucial for effective data processing with ChatGPT.

Step 2: Using ChatGPT to Identify and handle missing values

One of the primary challenges in survey data is missing values.

You can use ChatGPT to identify these gaps and suggest possible values or flag them for review.

For example, by inputting a prompt like:

"Find missing values in the survey data and suggest replacements based on similar entries.”

ChatGPT can provide useful suggestions to fill in the blanks.

Step 3: Correcting inconsistencies and standardising formats

Inconsistent data formats can cause significant issues in analysis.

ChatGPT can help by identifying and correcting these inconsistencies.

For instance, a prompt such as "Standardise date formats to YYYY-MM-DD and correct any discrepancies" will enable ChatGPT to standardise entries, ensuring uniformity across your dataset.

Step 4: Removing duplicates

Duplicate entries can skew your data analysis.

ChatGPT can assist in identifying and removing these duplicates.

By using a prompt like "Identify and remove duplicate survey responses, retaining the most complete record."

ChatGPT will ensure only unique entries are kept, maintaining data integrity.

Step 5: Final quality check

As you can see from my video tour, ChatGPT can also identify things like duplicate IP addresses, inconsistent answers, speedsters and much more.

A prompt such as "Perform a quality check on the cleaned survey data and report any remaining issues" can help in this final step, giving you confidence in your data's accuracy.

Benefits of using ChatGPT for data cleaning

Using ChatGPT for data cleaning offers several advantages such as:

- Improves data quality
- Improves reliability
- Saves time

With ChatGPT, you can focus on analysing high-quality data, leading to better business decisions and research outcomes.
