CSV files are lightweight and widely used for data analysis, import/export processes, and database management. Simplify handling hierarchical JSON structures by normalising them into rows and columns for better accessibility.
TSV (Tab-Separated Values) files, a close alternative to CSV, offer the same benefits while being particularly useful in scenarios where the data itself contains commas. By providing both CSV and TSV outputs, our tool ensures flexibility and compatibility with diverse workflows and applications.
