I need a small Windows-based utility that keeps Excel 365 running smoothly on my Windows 10 PC. The tool must: • Detect any active Excel sessions, close them gracefully, then force-kill lingering EXCEL.EXE processes if needed. • Relaunch Excel in Administrator mode and immediately open a spreadsheet defined in an external config file. • Monitor continuously—only during the days and hours I set in that same config file—for a run condition. My current trigger is simple: the appearance of a specific file inside a designated folder. • If the restart sequence ever fails, the utility should send me a clear notification (email or toast; I’m open to suggestions) rather than retrying endlessly or silently exiting. I’m flexible on the programming language as long as the final deliverable is a lightweight executable that runs without additional licenses. PowerShell, C#, or Python with PyInstaller are all fine—choose what lets you meet the brief quickly and reliably. Deliverables I expect: • Compiled executable ready to drop onto my machine. • Full source code with any build instructions. • A well-commented sample config file showing how to set run windows, trigger path, and target workbook. • A short read-me covering install steps, required permissions, and how your notification system works. This is strictly for personal use, so keep the solution straightforward but robust.
