Dynamic File Import

I have a model that is built off of four Excel files that are stored in a network folder. The network folder contains several files that aren't associated with my model, but I need the most recent version of the four files. My dilemma is that the files have datestamps, and files from previous days need to be kept for auditing purposes. My steps are as follows:

1. = Folder.Files("FolderPath")

2. = Table.SelectRows (Source, each
Text.Contains ([Name], "Text in Filename"))

3. = Table.Sort(Filtered,{{"Date modified", Order.Descending}})

4. = Table.FirstN(#"Sorted Rows",4)

5. = Table.SelectRows(#"Kept First Rows", each Text.Contains([Name], "Text in Filename"))

6. = #"Filtered Rows"{[#"Folder Path"="Filename with Specific Date"]}[Content]

How should I modify my steps so they find the most recent file that contains "X" in the name?

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
