FileExt Operator - Haufe-Lexware/haufe.no-frills-transformation GitHub Wiki

Use the FileExt operator to retrieve the extension (suffix) of a file name.

What	Type
Syntax	FileExt(fileName)
fileName	string
Return type	string

The operator looks for the last dot . in the file name and returns what is to the right of it.

Example: FileExt("C:\Temp\this_is_a_file.csv") will return csv.
