Table.PromoteHeaders

  • Raksts

Syntax

Table.PromoteHeaders(table as table, optional options as nullable record) as table

About

Promotes the first row of values as the new column headers (i.e. column names). By default, only text or number values are promoted to headers. Valid options:

  • PromoteAllScalars: If set to true, all the scalar values in the first row are promoted to headers using the Culture, if specified (or current document locale). For values that cannot be converted to text, a default column name will be used.
  • Culture: A culture name specifying the culture for the data.

Example 1

Promote the first row of values in the table.

Usage

Power Query M 
Table.PromoteHeaders(
    Table.FromRecords({
        [Column1 = "CustomerID", Column2 = "Name", Column3 = #date(1980, 1, 1)],
        [Column1 = 1, Column2 = "Bob", Column3 = #date(1980, 1, 1)]
    })
)

Output

Table.FromRecords({[CustomerID = 1, Name = "Bob", Column3 = #date(1980, 1, 1)]})

Example 2

Promote all the scalars in the first row of the table to headers.

Usage

Power Query M 
Table.PromoteHeaders(
    Table.FromRecords({
        [Rank = 1, Name = "Name", Date = #date(1980, 1, 1)],
        [Rank = 1, Name = "Bob", Date = #date(1980, 1, 1)]}
    ),
    [PromoteAllScalars = true, Culture = "en-US"]
)

Output

Table.FromRecords({[1 = 1, Name = "Bob", #"1/1/1980" = #date(1980, 1, 1)]})
