WP Data Converter - Free data converter CSV JSON XML Excel YAML | Portable without installation

Prérequis

WP Data Converter est compatible avec Windows 10 et 11 (x64). Aucune installation n'est requise, mais assurez-vous que votre système dispose de .NET 8.0 pour exécuter l'application.

Installation

WP Data Converter est une application portable. Téléchargez simplement le fichier exécutable unique (EXE) et placez-le dans le répertoire de votre choix. Vous pouvez également l'exécuter directement depuis une clé USB ou un disque dur externe.

Configuration

Les préférences de l'application sont automatiquement sauvegardées et restaurées à chaque lancement. Utilisez les quatre onglets organisés pour naviguer et configurer vos options de conversion.

Utilisation

  • Pour convertir un fichier, lancez l'application et utilisez le glisser-déposer pour importer vos fichiers directement dans l'interface.
  • Vous pouvez également utiliser le menu contextuel de Windows Explorer pour une conversion rapide par clic droit, sans ouvrir l'application.
  • Utilisez les options de ligne de commande --convert et --open pour intégrer WP Data Converter dans vos scripts batch ou automatisations.

Conversion et Aperçu

WP Data Converter offre une visualisation DataGridView des données avant conversion, limitée à 1000 lignes pour des raisons de performance. Cela permet une vérification visuelle avant l'export.

Scénarios d'usage

  • Professionnels : Convertissez des exports CSV en Excel pour des rapports ou transformez des fichiers Excel en JSON pour des API.
  • Développeurs : Transformez des fichiers de configuration YAML en JSON, générez des scripts SQL à partir de CSV, ou exportez en XML.
  • Data Analysts : Préparez vos données en convertissant entre formats et visualisez l'aperçu avant conversion pour vérifier la structure.
  • Étudiants : Utilisez cet outil gratuit et portable pour vos projets de cours, sans installation nécessaire.

Dépannage

Si vous rencontrez des problèmes lors de l'utilisation de WP Data Converter, assurez-vous que votre système est à jour et que .NET 8.0 est correctement installé. Vérifiez également que le fichier source est dans un format supporté.

Compatibilité

WP Data Converter prend en charge les formats de lecture suivants : CSV, TSV, JSON, XML, Excel (.xlsx), YAML, et les formats d'écriture suivants : CSV, JSON, XML, Excel, YAML, SQL, HTML.

Bonnes pratiques

  • Conservez une copie de sauvegarde de vos fichiers originaux avant de procéder à une conversion.
  • Utilisez l'aperçu intégré pour vérifier la structure des données avant de finaliser une conversion.
  • Pour des performances optimales, évitez de convertir des fichiers excessivement volumineux en une seule opération.
