How to convert an Object to JSON in Groovy without using any third party library?

Karthik Divi · Accepted Answer

You can achieve this natively in Groovy, without using any third-party library using `groovy.json.JsonOutput.toJson()` Following is the sample code

```java
​def colors = [ red : '#FF0000',
               black : '#000000',
               white : '#FFFFFF' ]
def jsonString = groovy.json.JsonOutput.toJson(colors);

println jsonString

```

### Output:
```json
{"red":"#FF0000","black":"#000000","white":"#FFFFFF"}

```
