# To Upper

The **To Upper** node is used to convert all the alphabets in the string to UpperCase.

### Properties Panel

#### General

| **Field**     | **Description**                                                                      | **Required** |
| ------------- | ------------------------------------------------------------------------------------ | ------------ |
| Node name     | [Node Name](https://docs.cosmocloud.io/concepts-and-in-depth/flow-builder/node-name) | true         |
| Variable Name | Variable name containing string which you want to convert to Upper Case              | true         |

### Example

Let's say you want to convert all the chracters in `cosmocloud` stored in `$.variables.company` to upper case.

1. Set `Variable Name` to `$.variables.company`.

It will convert the string in place and store in the same variable. If variable `$.variables.company` doesn't exist, it'll raise an error.

### Returns

This node does not return any value, but stores the modified string in the same variable provided in `<Variable Name>` in the flow context.

## 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.cosmocloud.io/flow-builder/node-types/variable-nodes/strings/to-upper.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.
