# JSON to XDR

> The JSON to XDR converter transforms JSON objects into base-64 encoded XDR format.

> [!NOTE]
>
> Learn more about JSON to XDR conversion tools [here](https://developers.stellar.org/docs/learn/fundamentals/data-format/xdr-json.md).

## Accessing the JSON to XDR Converter

To access the [JSON to XDR](https://lab.stellar.org/xdr/to) page, select "View XDR" from the left-hand navigation menu, then choose the "JSON to XDR" option from the submenu.

## Inputting JSON Data

On this page, you can enter a valid [XDR](https://developers.stellar.org/docs/learn/fundamentals/data-format/xdr.md) JSON object into the input field. To get sample data, navigate to the "[XDR to JSON](https://developers.stellar.org/docs/tools/lab/view-xdr/xdr-to-json.md)" page, then use the "Copy JSON" button located below the JSON output to copy a formatted object for testing purposes.

## Understanding the Output

After entering a valid JSON object, the interface displays two key components:

1. **XDR Type** – The identified type of XDR data, with an automatically pre-selected value. If the suggested type appears incorrect, you can select an alternative from the dropdown menu. A search function is available to help locate the appropriate type. ![Lab: XDR type dropdown](https://mintcdn.com/stellardevelopmentfoundation/hmWBKBicbGG4DTu6/assets/lab/lab-xdr-from-json-dropdown.png?fit=max\&auto=format\&n=hmWBKBicbGG4DTu6\&q=85\&s=0f2c4c3eb28be6ab04627dc11e173dd2)
2. **XDR Output** – A base-64 encoded XDR generated based on the selected XDR type. You can copy this output by clicking the copy button located below the field.
