## Why use Polars Extensions?

Polars Extensions fills in widely used convenience functions and transformations that many data workflows rely on — without needing custom ad-hoc code. Whether you need to:

- Read or write schema definitions to manage data structure programmatically  

- Convert between number formats (e.g. numbers ↔ Roman numerals, parse textual numbers)  

- Uniformly rename columns across naming conventions (snake_case, camelCase, kebab-case, PascalCase, etc.)  

- Compute approximate string-similarity (F1 similarity) for fuzzy matching or cleanup  

- Work with simple geospatial transformations (e.g. WKT/WKB ↔ coordinate formats)  

Polars Extensions provides a clean, expressive, and consistent API (using Polars expression namespaces) so you stay in the “Polars way” of data manipulation.
