Store: Extract Filename
Split the name of the incoming file into its filename, stem, and extension,
and emit each part as plain text. When the file's name carries a full path
(e.g. files coming from SFTP or blob storage), only the last path component is
kept (in/2026/Report.pdf → Report.pdf).
This function has no configuration.
Input
Filerequired
The file whose name is extracted. Accepts File or JSON (a JSON payload
is serialized to a file first).
Output
Filename
Complete filename including extension (e.g. report.pdf).
Stem
Filename without its extension (e.g. report).
Extension
Extension without the leading dot (e.g. pdf). Empty when the file has no
extension.
