# Modified Java Script Value

The Modified Java Script Value step provides a user interface for building JavaScript expressions that you can use to modify your data. The code you type in the script area is executed once per each row coming to the step. This step also allows you to create multiple scripts for in a single step.

This step is not a proper input step, and does not execute without an input. This step is a modified version of the JavaScript Values step, which has been deprecated and removed from PDI.

## 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.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview/modified-java-script-value.md?ask=<question>&goal=<endgoal>
```

`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.
