# <span style={{ 'color': 'gray' }}>class</span>  pixeltable.Row

A dict-like wrapper over a single result row.

Supports key access (`row['col']`), membership (`'col' in row`), iteration over keys, and the standard `get()`,
`keys()`, `values()`, and `items()` methods.

The `errors` property holds error info (`{'errortype': ..., 'errormsg': ...}`) for each cell whose
evaluation failed; the `index_values` property holds the values of embedding indexes defined on the
row's table. Both are keyed by column or index name.

## <span style={{ 'color': 'gray' }}>method</span>  to\_json()

```python Signature theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
to_json() -> dict[str, Any]
```

Return a JSON-serializable dict of this row's values.

* `None`: preserved as `None`
* Timestamp, Date: ISO 8601 string
* UUID: string
* Array: Python list (via `tolist()`)
* Json: validated for serializability, kept as native Python
* Binary: omitted (not representable in JSON)
* All others: unchanged
