Syntax
Table.TransformColumnNames(table as table, nameGenerator as function, optional options as nullable record) as table
About
Transforms column names by using the given nameGenerator
function. Valid options:
MaxLength
specifies the maximum length of new column names. If the given function results with a longer column name, the long name will be trimmed. Comparer
is used to control the comparison while generating new column names. Comparers can be used to provide case insensitive or culture and locale aware comparisons. The following built in comparers are available in the formula language:
Comparer.Ordinal
: Used to perform an exact ordinal comparisonComparer.OrdinalIgnoreCase
: Used to perform an exact ordinal case-insensitive comparison-
Comparer.FromCulture
: Used to perform a culture aware comparison
Example 1
Remove the #(tab)
character from column names
Table.TransformColumnNames(Table.FromRecords({[#"Col#(tab)umn" = 1]}), Text.Clean)
Column |
---|
1 |
Example 2
Transform column names to generate case-insensitive names of length 6.
Table.TransformColumnNames(
Table.FromRecords({[ColumnNum = 1, cOlumnnum = 2, coLumnNUM = 3]}),
Text.Clean,
[MaxLength = 6, Comparer = Comparer.OrdinalIgnoreCase]
)
Column | cOlum1 | coLum2 |
---|---|---|
1 | 2 | 3 |
