# Import and export transformation steps
Use the **Export** and **Import** commands to reuse transformation steps across multiple queries. Exporting a query creates a `.bck` file that contains its transformation steps. Then import the file into another query.
Reusing transformation steps helps maintain consistency across similar datasets and reduces the time required to recreate the same data preparation workflow.
Find the **Import** and **Export** commands on the **Transform** tab.
### Export transformation steps
The following example shows how to export transformation steps from a query.
1. Open the query that contains the transformation steps that you want to reuse.
2. Verify that the **Performed Steps** pane lists the required transformation steps.
3. On the **Transform** tab, select **Export**.
4. Save the generated `.bck` file to your computer.
The exported `.bck` file contains all transformation steps from the selected query.
### Import transformation steps
The following example shows how to import transformation steps into another query.
1. Open the target query.
2. On the **Transform** tab, select **Import**.
3. In the **Import Steps** dialog, browse to or drag and drop the exported `.bck` file.
4. After the file uploads successfully, select **Upload**.
5. After the import completes, the imported transformation steps appear in the **Performed Steps** pane of the target query.
Continue transforming the query, or write the transformed data to a destination.

## 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://docs.fabricplan.com/planning-sheets/how-tos/infobridge/data-transformations/import-and-export.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.
