Table.MaxN Function in Power Query

The Table.MaxN function returns the largest N rows from a table. After the rows are sorted, the countOrCondition parameter must be specified to further filter the result.

Syntax

Table.MaxN(table as table, comparisonCriteria as any, countOrCondition as any) as table

Note:

If a number is specified, a list of up to countOrCondition items in ascending order is returned.
If a condition is specified, a list of items that initially meet the condition is returned. Once an item fails the condition, no further items are considered.

Example: Find the top 3 records.

Power Query M

let
  MyTable = Table.FromRecords(
    {
      [CustomerID = 1, Name = "Ashish", Marks = 568], 
      [CustomerID = 2, Name = "Katrina", Marks = 855], 
      [CustomerID = 3, Name = "Alia", Marks = 380], 
      [CustomerID = 4, Name = "Vicky", Marks = 458], 
      [CustomerID = 5, Name = "Mohini", Marks = 278], 
      [CustomerID = 6, Name = "Meenakshi", Marks = 289], 
      [CustomerID = 7, Name = "Esha", Marks = 875], 
      [CustomerID = 8, Name = "Anjali", Marks = 380]
    }
  ), 
  #"Return Output" = Table.MaxN(MyTable, "Marks", 3)
in
  #"Return Output"
