# Find and Replace
In this document, you’ll learn how to use the Find and Replace function in Astera Dataprep to search for specific values and replace them with new ones across your dataset.
1. To begin, click on the *Cleanse* option in the toolbar and select *Find and Replace* from the drop-down.
2. This will open the *Recipe Configuration – Find and Replace* panel.
3. In this panel, you’ll configure the following options:
* Column Selection Properties
* **Apply to entire dataset**: Applies the find and replace action to all columns.
* **Apply to specific column(s)**: Applies the action to selected columns only.
* Find and Replace
* **Match Case**: Enable this checkbox to make the search case sensitive.
* **Find**: Enter the value you want to search for.
* **Replace:** Enter the value you want to replace it with.
4. Once you’re done, click *Apply* . In the Grid, you’ll see that all matching values have been replaced accordingly in the selected column(s).
5. Alternatively, you can right-click on any column header in the Grid and go to *Cleanse > Find and Replace.* The same configuration panel will appear with the column already selected. Make any changes you need and click *Apply* to update your data.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://documentation.astera.com/dataprep/cleanse/find-and-replace.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
