# Pandas formatting and conversion serve different uses

## Summary
Datasets can expose reads as Pandas objects or convert a dataset to a DataFrame. `with_format("pandas")` configures reads, while `to_pandas` performs an export. [S1]

## Details
The Pandas guide also provides `from_pandas` for importing a DataFrame. In formatted mode, `map` and `filter` can operate on Pandas batches. Passing `batched=True` lets a function process multiple rows together, and `batch_size` controls the batch size. The general guide notes that formatting happens as data is read and can be limited to selected columns. [S1, S2]
