Replicate Locked Spreadsheet Manually

I have a password-protected spreadsheet that won’t allow copy-paste, yet I still need every cell reproduced in an editable file. The source holds well over 500 rows with a mix of text entries and numerical figures. Nothing fancy in terms of formulas—just data that must appear exactly as it does now, including column widths, basic cell styles, and any bold or shaded headers.

Your task is simple but must be meticulous: open the locked file, read each value, and key it into a new Excel or Google Sheets document so that it mirrors the original layout and visual presentation. Accuracy matters far more than speed; a single misplaced digit or dropped character will cause problems downstream.

Deliverable: a fully editable spreadsheet that matches the source in content and basic formatting, ready for me to audit and start working with immediately.
