Map the work hiding in the spreadsheet
A spreadsheet often contains an unofficial business process: coloured cells mean approval, separate tabs represent stages, and comments hold important decisions. Observe how people actually use it before designing a replacement. List who creates records, who checks them, and which changes should trigger the next task.
Design around records and responsibilities
Turn repeated rows into clear records with stable identifiers. Define the important fields, allowed statuses and relationships. For example, a service request may belong to a customer, have several tasks and need one named owner. Give people access to the information and actions relevant to their role.
Move one workflow at a time
Start with a narrow process that causes measurable friction. Import a cleaned sample and let the team compare it with the spreadsheet. Keep an export available so information remains usable outside the application. Test duplicate records, incomplete data and simultaneous edits before relying on the new system.
Make the transition practical
Agree a cutover date for the chosen workflow and decide which system is authoritative from that point. Train the people who handle exceptions, not just the people who enter routine data. Keep a history of changes and a clear way to correct mistakes. Measure time spent finding information, correcting errors and chasing updates; those are often more useful indicators than the number of screens built.
