# `Table::clear` and `Table::replace`
Calling `Table::clear` will remove all data from the underlying `Table`. Calling
`Table::replace` with new data will clear the `Table`, and update it with a new
dataset that conforms to Perspective's data types and the existing schema on the
`Table`.
<div class="javascript">
```javascript
table.clear();
table.replace(json);
```
</div>
<div class="python">
```python
table.clear()
table.replace(df)
```
</div>
