How to Convert XML to JSON

Follow this 3-step workflow to convert your payloads with 100% privacy and zero server footprint.

01Step 1

Paste or Upload Your XML

Enter your XML code into the input editor, drop a .xml file, or click "Sample" to load a test template.

02Step 2

Real-Time AST Compilation

The client-side parser parses your input into an Abstract Syntax Tree and maps data types to JSON equivalents.

03Step 3

Customize Output & Copy / Export

Review the synthesized JSON output with full syntax highlighting, copy it with one click, or download as .json.
