La fonction ESTERR<\/strong> dans Microsoft Excel et Google Sheets est con\u00e7ue pour d\u00e9tecter les erreurs dans les donn\u00e9es, \u00e0 l’exception de l’erreur #N\/A<\/code>. Elle renvoie VRAI<\/code> si une cellule contient une erreur autre que #N\/A<\/code>, et FAUX<\/code> dans le cas contraire.<\/p>\n

Syntaxe de la fonction<\/h2>\n

La syntaxe de la fonction ESTERR<\/strong> est simple :<\/p>\n

=ESTERR(valeur)<\/code><\/pre>\n
    \n
  • valeur<\/strong> : La valeur \u00e0 tester. Peut \u00eatre une r\u00e9f\u00e9rence de cellule, une formule ou une valeur num\u00e9rique.<\/li>\n<\/ul>\n
    Exemples d’utilisation<\/h2>\n
    Consid\u00e9rons le tableau suivant dans une feuille de calcul :<\/p>\n\n\n\n\n\n
    A<\/th>\nB<\/th>\n<\/tr>\n
    5<\/td>\n0<\/td>\n<\/tr>\n
    Erreur #DIV\/0!<\/td>\n#VALEUR!<\/td>\n<\/tr>\n
    #N\/A<\/td>\n10<\/td>\n<\/tr>\n<\/table>\n
    Voici quelques exemples d’utilisation de ESTERR<\/strong> :<\/p>\n
      \n
    • =ESTERR(A2)<\/code> – Renvoie FAUX<\/code>, car A2 contient un nombre et non une erreur.<\/li>\n
    • =ESTERR(A3)<\/code> – Renvoie VRAI<\/code>, car A3 contient l’erreur #DIV\/0!, qui n’est pas #N\/A.<\/li>\n
    • =ESTERR(A4)<\/code> – Renvoie FAUX<\/code>, car A4 contient l’erreur #N\/A, exclue de cette fonction.<\/li>\n<\/ul>\n
      Sc\u00e9narios pratiques<\/h2>\n
      T\u00e2che 1: Filtrage des valeurs sans erreur<\/h2>\n
      Pour nettoyer une base de donn\u00e9es en \u00e9liminant les cellules contenant des erreurs (sauf #N\/A), la fonction ESTERR<\/strong> peut \u00eatre tr\u00e8s utile.<\/p>\n
      =SI(ESTERR(A2), \"\", A2)<\/code><\/pre>\n
      Cette formule examine si A2 contient une erreur (\u00e0 l’exception de #N\/A). Si c’est le cas, elle renvoie une cha\u00eene vide, sinon elle renvoie la valeur de A2.<\/p>\n
      T\u00e2che 2: D\u00e9compte des erreurs dans une plage de donn\u00e9es<\/h2>\n
      Pour compter le nombre de cellules contenant des erreurs dans une plage, combinez ESTERR<\/strong> avec NB.SI<\/strong>:<\/p>\n
      =NB.SI(A1:A4, \"=\"&ESTERR(A1:A4))<\/code><\/pre>\n
      Il est recommand\u00e9 d’utiliser une colonne d’assistance o\u00f9 chaque cellule refl\u00e8te le r\u00e9sultat de ESTERR<\/strong> pour la cellule correspondante, puis de compter combien retournent VRAI<\/code>.<\/p>\n","protected":false},"excerpt":{"rendered":"
