Dynamic File Import

Hi, JeffP25 

Maybe you can try the following expression:

let
    // Step 1: Get all the files in the folder
    Source = Folder.Files("FolderPath"),
  
    // Step 2: Filter for file names that contain "X".
    FilteredByText = Table.SelectRows(Source, each Text.Contains([Name], "X")),
  
    // Step 3: Extract the identifier in the file name (assuming the format is "Identifier_Date.xlsx")
    ExtractIdentifier = Table.AddColumn(FilteredByText, "Identifier", each Text.BeforeDelimiter([Name], "_")),
  
    // Step 4: Group by identifier and take the latest file for each group
    GroupAndSelectLatest = Table.Group(ExtractIdentifier, {"Identifier"}, {
        "LatestFile", each Table.Sort(_, {{"Date modified", Order.Descending}}){0}
    }),
  
    // Step 5: Expand and merge the file contents
    ExpandContent = Table.ExpandRecordColumn(GroupAndSelectLatest, "LatestFile", {"Content"}, {"Content"}),
    ImportExcelData = Table.TransformRows(ExpandContent, (row) => Excel.Workbook(row[Content]){0}[Data])
in
    ImportExcelData
