Les fichiers PRN traînent souvent dans les coins oubliés des systèmes informatiques — résidus d'anciennes imprimantes, exports de logiciels de gestion ou sorties brutes de machines industrielles. Leur contenu est pourtant bien réel : des données structurées, coincées dans un format que la plupart des outils modernes refusent d'ouvrir. La conversion vers CSV permet de redonner vie à ces fichiers, de les importer dans un tableur, de les croiser avec d'autres sources ou de les intégrer à un traitement automatisé. Que vous récupériez des relevés comptables, des listes d'inventaire ou des résultats d'analyses, l'essentiel est de ne pas perdre l'information en route — ni la virgule, ni le point-virgule, ni l'encodage des caractères accentués.
- Récupération de relevés issus de logiciels comptables suisses (Sage, Crésus)
- Extraction de données d'impression pour publications académiques françaises ou belges
- Traitement de sorties d'ateliers de prépresse et de studios de design québécois
En France et en Belgique, le séparateur décimal virgule et le point-virgule comme délimiteur CSV sont des conventions largement répandues, notamment dans les exports Excel francophones. Veillez à vérifier ces paramètres lors de la conversion pour éviter tout décalage de colonnes à l'ouverture.
