In QlikView I would run a loop to collect all the file names under a folder then use that to loop in and grab all the data. In Qlik Sense I've mapped a folder connection to the folder but I don't know how to get the data out of the folder:
LET vFilePath = '$(vEBIFiles)';
searchStr = '\*.xlsx*';
rootPath = '$(vFilePath)';
SUB DoDir (Root)
FOR EACH File IN FILELIST (Root&searchStr)
EBI_WeeklyFiles:
Load
'$(File)' as PathName,
'$(Root)' as Folder,
mid('$(File)',index('$(File)','\',-1)+1,len('$(File)')-index('$(File)','\',-1)) as FileName,
right('$(File)',len('$(File)')-index('$(File)','.',-1)+1) as FileExt,
Filesize('$(File)') as Size,
Filetime('$(File)') as FileTime
autogenerate 1;
next File
For Each SubDirectory in Dirlist( Root & '\*' )
Call DoDir(SubDirectory)
Next SubDirectory
END SUB
CALL DoDir (rootPath);
