The task involves creating an Alteryx workflow to process multiple Excel datasets (up to 10 files), combining them into a single Excel file with multiple sheets. The workflow will include options for grouping data by specified columns, calculating grand totals, and adding subtotals based on user input. The output will have consistent formatting across sheets, with bold headers, gray backgrounds, and specific placement for totals. Users will select files through a FileBrowse tool, and the file paths will be processed with Action and Formula tools to dynamically populate file names and reporting periods.
