Live Excel Sync From Local File

I need my working Excel file to mirror the contents of another Excel / CSV file that sits on the same computer. The moment that source file is saved with new data, the workbook you create must refresh itself—no buttons to press, no scheduled tasks, just an immediate update that feels truly real-time. You are free to use the most reliable approach: VBA with a file-change watcher, Power Query plus a lightweight macro, or any other method built into Microsoft Excel that keeps security prompts and external-link warnings to a minimum. What matters is that users can simply open the workbook and watch the figures change the instant the source does. Deliverables • A ready-to-use Excel workbook (or add-in) that links to the local Excel/CSV source and refreshes automatically on save • Clear, concise setup notes so I can relocate the files or change the source path without breaking the link • A brief test video or screenshots proving the live update Acceptance criteria 1. Target workbook updates within a few seconds of the source being saved 2. No manual interaction beyond normal editing of the source file 3. Solution runs on Windows 10/11 with standard Excel 365 installation, no extra paid software If you’ve built similar live-linking systems before, let me know—otherwise, show me how you’ll achieve the instant refresh and we can get started right away.
