A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
I think, the best thing to do is to use Excel's built-in Power Query and Slicers. It creates clean navigation buttons without breaking a sweat.
Here is the quick setup:
• Merge everything: Go to Data > Get Data > From File > From Folder. Point it at your main shared drive folder and hit Combine & Transform. Excel will automatically dig through all the subfolders and pull the data into one master sheet.
• Make the buttons: Click anywhere inside your new master table, head up to the Table Design tab, and click Insert Slicer.
• Set the levels: Check the boxes for Folder Path and File Name. This drops clickable buttons right onto your sheet. Your employee can click a folder level, see the filtered files, and print immediately.
