Comment convertir XML en JSON en ligne

  1. Étape 1 – Coller ou importer du XML

    Collez du XML dans l’éditeur de gauche ou importez un fichier .xml.

  2. Étape 2 – Inspecter la structure

    Au fur et à mesure de l’édition, l’outil analyse le XML et le convertit en arbre d’objets JSON (éléments, attributs, nœuds imbriqués).

  3. Étape 3 – Vérifier la sortie JSON

    Le JSON apparaît à droite, formaté pour la lecture. Les erreurs XML s’affichent au-dessus des éditeurs.

  4. Étape 4 – Copier ou télécharger le JSON

    Copiez le JSON converti ou téléchargez-le en .json pour vos APIs, tests ou applications.

Quick tips for XML to JSON

  • Well-formed XML is required; unclosed tags or invalid characters will cause parse errors.
  • Attributes are usually mapped with a prefix (like @), and text nodes with #text.
  • After converting, you can generate JSON Schema or TypeScript types for the resulting JSON structure.
Example: XML to JSON
<!-- XML input -->
<order id="ORD-1001">
  <customer name="Maeve" email="[email protected]" />
  <item sku="SKU-001">Wireless Mouse</item>
  <item sku="SKU-002">Mechanical Keyboard</item>
</order>

// JSON output (simplified)
{
  "order": {
    "@id": "ORD-1001",
    "customer": {
      "@name": "Maeve",
      "@email": "[email protected]"
    },
    "item": [
      { "@sku": "SKU-001", "#text": "Wireless Mouse" },
      { "@sku": "SKU-002", "#text": "Mechanical Keyboard" }
    ]
  }
}

Questions fréquentes

What XML features are supported in the conversion?

The converter supports standard XML elements, attributes, text content, and CDATA sections. It handles nested structures and converts them to appropriate JSON objects and arrays.

How are XML attributes handled in the JSON output?

XML attributes are typically converted to JSON properties with a special prefix (like '@') to distinguish them from element content, or they may be merged into the element's JSON representation depending on the conversion logic.

Can I convert large XML files?

Yes, the converter can handle large XML files, but performance may vary based on file size and complexity. For very large files, consider breaking them into smaller chunks if possible.

What happens to XML namespaces during conversion?

XML namespaces are preserved in the JSON output, typically as part of the element names or as separate properties. The exact handling depends on the conversion implementation.
