Automated Excel Data Organizer

I need a clean, user-friendly Excel workbook that lets me paste or type mixed text-and-number records into a single input area and immediately sorts everything by the date-or-time field I specify.
Here is what I’m after: as soon as new rows are added, the sheet should re-order them chronologically without my having to click a button. To keep the database reliable, I also want built-in data validation that stops wrong date formats or empty required cells, and conditional formatting that instantly flags duplicates or highlights approaching deadlines.

Please structure the file so it is easy for a non-technical user to expand later (clear table headers, no hidden macros unless truly necessary). If you prefer using Power Query or a small VBA routine for the auto-sort, just make sure it runs seamlessly in current 365 versions.

Deliverable is the finished .xlsx ready to use, along with a brief note in the workbook explaining where to enter data, how validation works, and how to tweak the conditional rules if my criteria change down the road.
