Enhance a dataset using OpenAI   Attend the course: Enhance your dataset using OpenAI What you will learn: Create and use data frames Create and use data api's Use Python OpenAI to enhance data: This Python lesson demonstrates how to use OpenAI to enhance and standardize data stored in an Excel spreadsheet.  The program reads an Excel file into a pandas DataFrame,  processes the records in manageable batches,  sends the data to an OpenAI model for improvement,  and writes the enhanced results back into a new Excel file. You will maintain the original structure of the dataset by keeping the existing column names unchanged while improving data quality, such as correcting spelling, standardizing formatting, and cleaning company and address information. This approach allows Python users to automate large-scale data enhancement tasks while preserving the original spreadsheet format.   Attend the course: Enhance your dataset using OpenAI
