Power Query Max If is a powerful function available in Power Query that allows you to find the maximum value in a specified column based on certain conditions. It is commonly used by programmers to extract the maximum value from a dataset that meets specific criteria.
The syntax for the Power Query Max If function is as follows:
MaxIf(column, condition)
column
: The column from which you want to find the maximum value.condition
: The condition that must be satisfied for a value to be considered in the calculation of the maximum.The Power Query Max If function is typically used within a transformation step in Power Query. Here's an example of how you can utilize it:
let
source = #table(
{"Name", "Age"},
{{"John", 25},
{"Jane", 30},
{"Mike", 35},
{"Emily", 40}}
),
maxAge = MaxIf(source[Age], [Age] > 30)
in
maxAge
In this example, we have a table with two columns: "Name" and "Age". We want to find the maximum age from this table for individuals whose age is greater than 30. The MaxIf
function is used to achieve this by providing the "Age" column and the condition [Age] > 30
. The result will be the maximum age that satisfies the condition.
MaxIf
function can be any valid expression that evaluates to a boolean value.The Power Query Max If function is a useful tool for programmers working with Power Query. It allows you to easily find the maximum value from a column in your dataset based on specific conditions. By incorporating this function into your data transformation workflow, you can extract valuable insights from your data.
