# fill_from_mapping

Fill form fields using an explicit index-based mapping produced by `extract_form_fields`.

```python theme={null}
fields = await page.extract_form_fields()
await page.fill_from_mapping(
    form_fields=fields,
    mapping={0: "John", 1: "Doe"},  # keys are field indices from extract_form_fields
    data={"name": "John Doe"},
)
```
