How to get datepart in Expressions

Hi CeeVee33 , Thank you for reaching out to the Microsoft Community Forum.

1. To dynamically create the folder path and filenames based on today's date in Microsoft Fabric Pipelines, you can use the following expressions directly in the pipeline.

Folder path: @concat('\\Servername\ABCFolder\',

         formatDateTime(utcNow(), 'yyyy'), '\\',

         formatDateTime(utcNow(), 'MMMM').ToUpper(), '\\',

         formatDateTime(utcNow(), 'dd.MM.yyyy'))

Output: \\Servername\ABCFolder\2025\MARCH\20.03.2025

               Example File1: @concat('MyFirstFav_', formatDateTime(utcNow(), 'ddMMyyyy'),                '.csv')

Output: MyFirstFav_20032025.csv

Example File2: @concat('MySecondFav_', formatDateTime(utcNow(), 'ddMMyyyy'), '.csv')

Output: MySecondFav_20032025.csv

2. To Ingest Multiple CSVs into a Table in Fabric, create a Pipeline, use a Get Metadata activity to list the files in the dynamic folder path. Use a ForEach Activity, Iterate over the file list. Copy Data into a Table, Use a wildcard file path: \\Servername\ABCFolder\@{formatDateTime(utcNow(), 'yyyy')}\@{formatDateTime(utcNow(), 'MMMM').ToUpper()}\@{formatDateTime(utcNow(), 'dd.MM.yyyy')}\*.csv . Configure the Sink, point to your Lakehouse table, Use Auto Mapping to map CSV columns to table columns. Add a Trigger, set the pipeline to run daily.
