Le NDJSON — ou JSON délimité par des sauts de ligne — s'est imposé dans les flux de données modernes : APIs, journaux applicatifs, exports de bases documentaires. Pratique pour les machines, il l'est beaucoup moins pour quiconque doit relire, croiser ou transmettre ces données à des collègues non techniques. Le CSV, lui, s'ouvre dans Excel, LibreOffice Calc ou Numbers sans la moindre configuration. Cette conversion vous évite de bricoler un script Python un vendredi après-midi : collez votre fichier, téléchargez le tableau. Les en-têtes sont détectées automatiquement, les valeurs imbriquées aplaties selon une logique lisible. Idéal quand on travaille vite, quand on partage beaucoup, ou quand on préfère simplement ne pas expliquer ce qu'est le NDJSON à son directeur de projet.
- Exports de données Sirene ou data.gouv.fr à analyser sous tableur
- Fichiers de soumission pour publications académiques en sciences sociales (CNRS, universités francophones)
- Catalogues produits d'agences de design ou de studios créatifs à intégrer dans des outils de gestion
En France et en Belgique, de nombreux portails open data publics distribuent leurs jeux de données en NDJSON pour les gros volumes, mais les services administratifs et les partenaires institutionnels continuent de travailler quasi exclusivement avec des fichiers CSV ou Excel. La conversion reste donc une étape courante dans tout flux de traitement de données publiques.
