I have a growing collection of Excel spreadsheets that need to flow automatically into our system instead of being keyed in by hand. The goal is a reliable, repeatable process that can read each file, map the right columns, and push the records to our destination table with zero manual touch-ups. Here’s what I’m after: • A small, self-contained script or utility that watches a folder (or accepts a drag-and-drop run), ingests any new .xlsx file, validates the headers, and inserts the data into the target sheet/database table. • Basic data hygiene built in—duplicate detection, date and number formatting, and a simple error log so I can see why any row was skipped. • Clear, commented source code plus a quick setup guide so future teammates can tweak paths, column names, or add fields without hunting through the logic. If you’ve built similar automated data-entry tools before, especially around Excel, let me know what languages or platforms you prefer and share one concrete example of where your automation saved time. I’ll shortlist pros who can demonstrate hands-on experience rather than generic promises.
