How can I dedup across rows and columns in a pivot table?

[ereed18]

I have a pivot table with data, but I need to find the number of times these values occur. However, a user can input the same value in different fields causing the same value to appear on different rows and in different columns. How can I dedup across all rows and columns to return the single value and total count it occurs?

For example:

Pivot

Col1         Col2             Col3
Here         NULL             NULL
NULL         There            Anywhere
Here         NULL             Here
Here         Here             NULL

Assuming you want to find the count of a specific string in all rows and columns, try this.

your current search giving output mentioned in the question 
| eval temp=1 | untable temp colname colvalue | where colvalue="YourSpecificString"
| stats count
