range : النطاق الذي تريد حساب عدد الخلايا الفارغة داخله .

مثال على دالة COUNTBLANK

الجدول التالي يحتوي على رقم الموظف Employee ID واسم الموظف Employee Name ونريد حساب عدد الخلايا الفارغة في عمود اسم الموظف .

لعمل ذلك سنستخدم دالة COUNTBLANK كما هو موضح في المعادلة التالية :

COUNTBLANK(B2:B11)=

في هذه المعادلة ستقوم دالة COUNTBLANK بحساب عدد الخلايا الفارغة داخل النطاق B2:B11

طبقا لذلك دالة COUNTBLANK سترجع الرقم 2 أي يوجد 2 خلية فارغة داخل النطاق B2:B11 وهما الخلية B4 والخلية B8

دالة COUNTBLANK

ملحوظة :

- اذا كنت تريد حساب عدد الخلايا التي تحتوي على أرقام فقط داخل نطاق قم بقراءة هذا الدرس : دالة COUNT
