DAX Query for Count of Blank Cells

[Sajay_Prathap24]

Dears....I have a excel database and ther are some cells not filled. From Power BI, I need to know the count of those blank cells based on which column the blank cells is available. Please advise for the DAX query for this

For Eg: Column A = 4, Column D = 6

there are several ways to do this, I would suggest you to use the column statistics in DAX query view. It gives all the statistics in view. 
https://learn.microsoft.com/en-us/power-bi/transform-model/dax-query-view
Open DAX query view, on the right hand side you will find all the tables in your model. 

Right click on the table, click on Qucik queries -> click on Show column statistics. 

In the result tab, you will see a column caled Null count. 

You can also find blank or empty values from power query column profiling options. 'Column quality'

https://learn.microsoft.com/en-us/power-query/data-profiling-tools

However by default it will only profile top 1000 rows and the results would show in percentage.

Option 1: Count Blank Cells for Each Column

Create a measure for each column:
Count_Blanks_ColumnA = COUNTROWS(FILTER(YourTable, ISBLANK(YourTable[ColumnA])))
Count_Blanks_ColumnD = COUNTROWS(FILTER(YourTable, ISBLANK(YourTable[ColumnD])))
Replace YourTable, ColumnA, and ColumnD with your actual table and column names.

Option 2: Count Blanks Dynamically for All Columns

Unpivot the columns in Power Query:

1. Select your columns and use Unpivot Columns.
2. Add a custom column: IsBlank = IF(ISBLANK([Value]), 1, 0)
3. Group by the column name and sum IsBlank.

Option 3: Dynamic Measure for All Columns

To calculate blanks across all columns: Count_Blanks_All =

SUMX(ADDCOLUMNS(
VALUES(YourTable[ColumnName]),"BlankCount", COUNTROWS(FILTER(YourTable, ISBLANK(YourTable[ColumnName])))),[BlankCount])

Use in a table/matrix visual for column-wise blank counts.

Hello @Sajay_Prathap24 ,

the way it will work for you is to do it per column

BlankCount_ColumnA = 
calculate(
COUNTROWS(Table), table[columnName] = blank)

You can try:

CountBlanks_ColumnA = COUNTROWS(FILTER('Table', ISBLANK('Table'[ColumnA])))
CountBlanks_ColumnD = COUNTROWS(FILTER('Table', ISBLANK('Table'[ColumnD])))
