Table.Pivot

Syntax

Table.Pivot(table as table, pivotValues as list, attributeColumn as text, valueColumn as text, optional aggregationFunction as nullable function) as table

About

Given a pair of columns representing attribute-value pairs, rotates the data in the attribute column into a column headings.

Example 1

Take the values "a", "b", and "c" in the attribute column of table ({ [ key = "x", attribute = "a", value = 1 ], [ key = "x", attribute = "c", value = 3 ], [ key = "y", attribute = "a", value = 2 ], [ key = "y", attribute = "b", value = 4 ] }) and pivot them into their own column.

Table.Pivot(
    Table.FromRecords({
        [key = "x", attribute = "a", value = 1],
        [key = "x", attribute = "c", value = 3],
        [key = "y", attribute = "a", value = 2],
        [key = "y", attribute = "b", value = 4]
    }),
    {"a", "b", "c"},
    "attribute",
    "value"
)
key a b c
x 1 3
y 2 4

Example 2

Take the values "a", "b", and "c" in the attribute column of table ({ [ key = "x", attribute = "a", value = 1 ], [ key = "x", attribute = "c", value = 3 ], [ key = "x", attribute = "c", value = 5 ], [ key = "y", attribute = "a", value = 2 ], [ key = "y", attribute = "b", value = 4 ] }) and pivot them into their own column. The attribute "c" for key "x" has multiple values associated with it, so use the function List.Max to resolve the conflict.

Table.Pivot(
    Table.FromRecords({
        [key = "x", attribute = "a", value = 1],
        [key = "x", attribute = "c", value = 3],
        [key = "x", attribute = "c", value = 5],
        [key = "y", attribute = "a", value = 2],
        [key = "y", attribute = "b", value = 4]
    }),
    {"a", "b", "c"},
    "attribute",
    "value",
    List.Max
)
key a b c
x 1 5
y 2 4
