\u00davod do funkce na detekci chyb<\/h2>\n

Funkce ISERROR<\/strong> (v \u010de\u0161tin\u011b jako JE.CHYBHODN<\/strong>) je u\u017eite\u010dn\u00fd n\u00e1stroj v MS Excel i Google Sheets, kter\u00fd se pou\u017e\u00edv\u00e1 k identifikaci bun\u011bk, kter\u00e9 obsahuj\u00ed chybov\u00e9 hodnoty.

Syntaxe a pou\u017eit\u00ed funkce<\/h2>\n

Syntaxe funkce je relativn\u011b jednoduch\u00e1 a stejn\u00e1 pro MS Excel i Google Sheets:<\/p>\n

=ISERROR(hodnota)<\/code><\/pre>\n
Kde hodnota<\/em> m\u016f\u017ee b\u00fdt bu\u010f p\u0159\u00edmo hodnota, nebo odkaz na bu\u0148ku \u010di v\u00fdraz, jeho\u017e chybnost je zkoum\u00e1na.<\/p>\n
    \n
  • Vrac\u00ed TRUE<\/strong> (PRAVDA), pokud je hodnota chybov\u00e1 (nap\u0159. #DIV\/0!, #N\/A, #NAME?, atd.).<\/li>\n
  • Vrac\u00ed FALSE<\/strong> (NEPRAVDA), pokud hodnota chybov\u00e1 nen\u00ed.<\/li>\n<\/ul>\n
    P\u0159\u00edklady pou\u017eit\u00ed:<\/p>\n
    =ISERROR(A1) \/\/ Vr\u00e1t\u00ed PRAVDA, pokud bu\u0148ka A1 obsahuje chybu, jinak NEPRAVDA =ISERROR(1\/0) \/\/ V\u017edy vr\u00e1t\u00ed PRAVDA, proto\u017ee d\u011blen\u00ed nulou je chyba =ISERROR(\"Text\") \/\/ Vr\u00e1t\u00ed NEPRAVDA, proto\u017ee text nen\u00ed chybov\u00e1 hodnota<\/code><\/pre>\n

    \u00dakol 1: Filtrov\u00e1n\u00ed chybov\u00fdch hodnot v datov\u00e9m setu<\/h3>\n
    P\u0159edstavte si, \u017ee m\u00e1te tabulku s finan\u010dn\u00edmi daty a v jednom sloupci jsou v\u00fdpo\u010dty, kter\u00e9 mohou obsahovat chyby. C\u00edlem je vytvo\u0159it nov\u00fd sloupec, kter\u00fd ukazuje, zda p\u016fvodn\u00ed sloupec obsahuje chybu.<\/p>\n
     A B 1 Hodnota Chybn\u00fd? 2 500 3 0 4 =1\/0 5 300 <\/code><\/pre>\n

    =ISERROR(A2)<\/code><\/pre>\n
    Tato funkce identifikuje, zda bu\u0148ka A2 obsahuje chybu (B2 bude m\u00edt hodnotu PRAVDA, pokud A2 obsahuje chybu).<\/p>\n
    \u00dakol 2: Kondi\u010dn\u00ed form\u00e1tov\u00e1n\u00ed pro zv\u00fdrazn\u011bn\u00ed chybov\u00fdch bun\u011bk<\/h3>\n

    200<\/td>\nDobr\u00e9<\/td>\n<\/tr>\n<\/table>\n
    Pro implementaci vyberte sloupec, kde chcete hledat chyby, klikn\u011bte na Kondi\u010dn\u00ed form\u00e1tov\u00e1n\u00ed, vyberte „Pou\u017e\u00edt vzorec k zaji\u0161t\u011bn\u00ed, kter\u00e9 bu\u0148ky maj\u00ed form\u00e1tovat“ a pou\u017eijte vzorec:<\/p>\n
    =ISERROR(A1)<\/code><\/pre>\n
    Nastavte form\u00e1tov\u00e1n\u00ed (nap\u0159. \u010derven\u00e9 pozad\u00ed), a v\u0161echny bu\u0148ky s chybami budou zv\u00fdrazn\u011bn\u00e9.<\/p>\n

    Funkce ISERROR<\/strong> (JE.CHYBHODN) je velmi praktick\u00fd n\u00e1stroj pro identifikaci a manipulaci s chybov\u00fdmi hodnotami v r\u00e1mci pr\u00e1ce s datasety v MS Excel a Google Sheets.
