# Text Java Properties Format

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

MIME Type: `text/x-java-properties`

ID: `properties`

The Text Java Properties format parses any Java properties file. This format represents simple
key-value pairs. DataWeave represents these pairs as an object with string values.

## Example: Represent a properties File in the DataWeave Format (dw)

This example shows how DataWeave represents a properties file.

### Input

The following `text/x-java-properties` data is from a properties file. The file contains key-value
pairs that provide host and port values. This content serves as the input payload to the DataWeaave
script.

```properties
host=localhost
port=1234
```

### Source

The DataWeave script transforms the `text/x-java-properties` input payload to the DataWeave (dw)
format and MIME type. It returns a string.

```dataweave
%dw 2.0
output application/dw
---
payload
```

### Output

The output is an object in the DataWeave (dw) format. The object contains a collection of key-value
pairs that match the `text/x-java-properties` input. Notice that the output wraps the values in
quotation marks.

```dataweave
{
    host: "localhost",
    port: "1234"
}
```
