I’m sitting on a folder full of Excel workbooks whose columns are currently aggregated by week. That setup no longer works for our reporting: some of those fields must be broken out to daily granularity, others have to stay weekly, and a third group actually needs to recalculate dynamically based on values in the newly-created daily columns. Because every file follows the same broad layout but with small inconsistencies, I need a robust, repeatable solution rather than hours of manual copy-and-paste. Here’s the core of what I’m after: • A script, macro, or Power Query routine that scans each workbook, converts only the specified columns to daily data points (I’ll supply the exact mapping), keeps designated columns untouched at weekly level, and then builds the dependent columns according to simple formulas I’ll also provide. • Output files that mirror the original naming conventions so they can drop straight back into our pipeline. • A short read-me so that a non-developer on my team can rerun the process when new workbooks arrive. Whether you use native Excel functions, VBA, Python + pandas, or an AI-driven approach is entirely up to you—the end result just needs to be accurate and runnable on a standard Windows machine with Office 365. If this sounds like the sort of data wrangling you enjoy, let’s talk specifics and get these files cleaned up.

Hello there! I understand that you need a robust, repeatable solution to convert specific weekly columns in multiple Excel workbooks into daily granularity, while keeping some columns at the weekly level and recalculating dependent fields according to your formulas. I can create a script, macro, or Power Query routine that processes each workbook accurately, outputs files with the original naming conventions, and includes a clear read-me so your team can rerun the process seamlessly. My approach ensures efficiency, accuracy, and ease of use across all your files. Here are a few questions to clarify your requirements: Can you provide the exact column mapping and formulas for the dependent calculations? Are there any variations in file structure we should account for beyond the “small inconsistencies” mentioned? Do you have a preferred technology—VBA, Python, or Power Query—or should I recommend the most reliable approach for your workflow? Here's my portfolio for your review: https://www.freelancer.com/u/Penmate .
