Every morning open four Excel workbooks from two servers, copy and merge data (pairwise), run a VLOOKUP to pull operational reference data, tidy layouts and save two results as “Nationwide Locked Huawei Lithium Batteries” and “Communication Break Alarms Summary”, export both results to CSV, launch Outlook via win32com, create an email to the usual distribution list, embed the two tables in the message body with bold headers and clear borders, attach the two CSVs and send automatically, store configurable items (paths, sheet names, recipients, subject) in a JSON/INI, package the script as a single .exe with PyInstaller, and fail gracefully with clear error messages if workbook formats change. This is a simple job of writing a python script.
