What Type of Formats Can ChatGPT Handle for Data Analysis?

The Straight Facts on Data Formats Supported by ChatGPT

ChatGPT processes several data formats to help you find patterns and extract insights. Understanding how to prepare your data for ChatGPT can boost the accuracy and efficiency of your analysis.  

Text-Based Data

ChatGPT supports text-based data formats to help users clean, organize, and analyze textual datasets. Supported formats include:

• Plain text files (e.g., .txt files).

• Exported CSV or TSV files saved as plain text.

• JSON strings containing structured text data.

Applications of text-based data analysis include cleaning and organizing large datasets (e.g., customer feedback or survey responses) and extracting insights (e.g., recurring keywords or sentiment analysis). For example, ChatGPT can analyze a CSV file containing user feedback, where each row represents a comment. The AI can classify these rows as positive, negative, or neutral based on sentiment.    

Spreadsheet Data (with Tools Like Numerous)

ChatGPT also analyzes spreadsheet data with the help of tools like Numerous. Supported formats include Excel (.xlsx, .xls) and Google Sheets files. However, effective interaction with this type of data requires integration via Numerous. 

Applications include automating repetitive tasks like summarization, categorization, or trend identification across rows. For example, you can analyze sales trends by categorizing products in one column and summarizing regional performance in another.  

Unstructured Data

ChatGPT can help users make sense of unstructured data, including chat logs, email threads, or raw text files. Applications include parsing unstructured data to identify patterns, extract key points, or organize them into structured formats. For example, you can manage customer inquiries from emails into categories like product questions, complaints, and general feedback.  

Getting Your Data Ready for ChatGPT

Data must be preprocessed and organized to maximize accuracy and efficiency before feeding it into ChatGPT. 

Cleaning the Data

The cleaner the data, the better ChatGPT performs. Irrelevant noise and inconsistencies can throw off the AI and negatively impact your results. To clean your data, remove duplicate entries, eliminate non-essential data points (e.g., random symbols or formatting issues), and standardize formats, such as capitalizing names or normalizing dates. 

For example, let’s say you have a column of customer names with mixed-case formatting: "JOHN," "jane," "and Alice." You would use a cleaning prompt like: “Standardize the format of all names in column A to proper case.”  

Structuring the Data

ChatGPT excels when it can recognize patterns and structures in the data. To structure your datasets, group related data points into rows and columns for tabular formats. Next, label each column clearly to provide context, such as "Feedback," "Date," and  "Region." 

For example, if you had a survey dataset, you would create columns like "Question," "Response," and "Sentiment." Use these labels in prompts for precise outputs.  

Segmenting Data for ChatGPT

ChatGPT has input size limitations and may need to handle vast datasets more effectively. To segment your data, divide datasets into smaller chunks (e.g., 100 rows at a time). Process each chunk independently and merge results afterward.  

For example, if you had a large dataset of 1,000 survey responses, you would divide it into ten batches of 100 rows each and analyze trends per batch.  

Using Numerous for Seamless Integration

Numerous enhancements have been made to ChatGPT’s capabilities for spreadsheet-based data analysis. Key features include:

• Automating repetitive tasks across entire datasets, such as categorization or sentiment analysis.

• Supporting large datasets by processing data directly within Google Sheets or Excel.

• Enabling drag-and-drop application of ChatGPT-generated functions across multiple rows and columns.  

For example, let’s say you had a Google Sheet with columns for "Product Name" and "Customer Review." You could use ChatGPT through Numerous to categorize reviews in one column and summarize customer sentiment in another. The output would be automated summaries and classifications across hundreds of rows.  

Limitations and Workarounds

While ChatGPT supports a wide range of formats, certain constraints must be considered:  

Volume Constraints

ChatGPT cannot directly process massive datasets. A good workaround is to use Numerous to batch-process data and handle larger volumes effectively.  

Ambiguity in Unstructured Data

ChatGPT may need help to interpret poorly organized or ambiguous data. A solid workaround is to preprocess data and use clear, detailed prompts for accurate results.  

Lack of Built-In Visualization

ChatGPT cannot create charts or graphs from data. A simple workaround is to export ChatGPT outputs to Excel or Google Sheets for visualization.
