Moving a workflow from Excel to a web system requires preparing the work that already exists. Copying files without reviewing their data, rules, and owners can reproduce the same confusion in a different tool.

1. Define the workflow you will migrate

Set its starting point and finish, who takes part, and what result it should produce. If a spreadsheet supports several tasks, first separate the ones that belong to the workflow you selected.

2. Gather and review the data sources

Find the current spreadsheets, identify duplicates, and agree on which source is valid when records differ. Review formats, blank fields, inconsistent names, and records that should no longer be kept.

3. Define what the data means

Document each column, required fields, and valid values. Also clarify who can view or change each record and which changes need to be tracked.

4. Test the import with a sample

Use a representative set that includes common cases and exceptions. Compare the source records with those shown in the system and correct the field mapping before importing the rest.

5. Run a pilot and agree on the transition

A small group can complete the workflow, ask questions, and find missing steps. Before switching, decide when the old spreadsheet stops being updated and where historical records can be found.

6. Migrate in stages and validate the result

After the pilot, add the agreed workflow and check that imported records, permissions, and reports match expectations. Document how to report issues and who will handle adjustments.

The plan depends on the condition of the files and the workflow rules; importing every historical sheet is not always useful. Process automation and internal systems can centralize a workflow now coordinated through files and messages.
