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.
