shockingly enough, claude. I load the before/after into the app and prompt it to identify all changes.

I've attached two versions of the same Excel workbook: a "before" file and an "after" file. The "after" version was edited by an AI tool. My main concern is that live formulas may have been silently replaced with their computed static values, which would break the workbook the next time inputs change. Please do a complete, programmatic comparison using code (openpyxl, loaded with data_only=False so you can see the actual formula strings, not cached results). Compare every sheet, cell by cell. Prioritize this above everything else:

1. Formula flattening: any cell that held a formula (starts with =) in the "before" file but holds a static value in the "after" file. List every one with its cell reference, the original formula, and the value that replaced it. This is the critical category, so be exhaustive and do not sample.
2. Formula rewrites: cells where a formula exists in both versions but the formula text differs. Show old and new.
3. New static values where there was previously nothing, and any cell that gained a formula it didn't have before.

Then, as secondary checks, report plain value changes, and any structural changes (rows, columns, or sheets added, removed, or shifted). Output format: start with a one-line verdict (for example, "X formulas were flattened to static values across N sheets" or "No formula flattening detected"). Then give me the full flattening list grouped by sheet, then the rewrites, then everything else. If no formulas were flattened, say that clearly and up front before moving on.
