Introduction to Data Polisher

Data Polisher is a specialized tool designed to streamline the process of cleaning and preparing CSV data files for analysis or application. Its core functionality revolves around identifying and resolving common data quality issues automatically, such as missing values, duplicates, inconsistent formatting, and erroneous data entries. The purpose behind Data Polisher is to save time and reduce the complexity involved in data preprocessing, making data more usable and reliable for analysis or application development. For example, if a user uploads a CSV file containing a mix of date formats or some unexpected null values, Data Polisher will detect these issues, suggest standardized formats, and offer options to fill or remove null values, ensuring the dataset's consistency and integrity.
