A simple spreadsheet tip: give every record a unique ID, keep date formats consistent, and use a follow-up column so the next action is easy to find. I have added four fictional-data portfolio samples showing my approach to customer directories, invoice tracking, data-entry quality checks, and administrative workflows. I am available for data entry, spreadsheet cleanup, contact and invoice tracking, document formatting, and virtual administrative support. Starting rate: $25/hour, with scope and timing agreed before work begins. View my samples and services: https://contra.com/jassette_donaldson_hanfibwj/work
